Early Life and Background

Family Heritage and Childhood

Eric E. Teller, known professionally as Astro Teller, was born in , , in 1970. His family relocated to the when he was approximately two or three years old, settling initially in areas connected to his parents' academic pursuits before he was raised primarily in . Teller's paternal grandfather was , the Hungarian-American theoretical physicist renowned for his contributions to , including key roles in the development of the atomic and hydrogen bombs during the and subsequent U.S. weapons programs. His maternal grandfather, Gérard Debreu, was a French-American economist who received the in Economic Sciences in 1983 for his work on and . Teller's father, Paul Teller, is a philosopher who earned a PhD from MIT and conducted postdoctoral work, influencing a household environment steeped in intellectual and scientific discourse. From an early age, Teller displayed an aptitude for , engaging with and amid this lineage of prominent scientists and thinkers, though specific childhood anecdotes beyond familial relocation and academic surroundings remain limited in public records.

Upbringing and Influences

Eric Teller, known as Astro, was born in , , in 1970 and moved to the at age two and a half, spending his formative years primarily in , from ages three to eighteen. He briefly lived in , for eighteen months during his freshman year of high school. Raised in an intellectually rigorous household that emphasized academic achievement, Teller grew up expecting to pursue a PhD, with business ventures initially viewed skeptically by his family. Family dinners often featured discussions involving sketches and equations, fostering an environment of curiosity and problem-solving. His parents shaped this milieu: his father, Paul Teller, held a PhD in philosophy and served as a professor of at the University of Illinois at Chicago, while his mother, Chantal DeSoto, worked as a clothing designer and buyer for Roebuck & Company before teaching gifted children. This blend of philosophical inquiry and creative application influenced Teller's early worldview, blending analytical rigor with practical innovation. During high school at , he demonstrated leadership by co-captaining the soccer team, and adopted the nickname "Astro" in 1985 after teammates compared his flattop haircut to —a moniker that endured despite the hairstyle's brevity. Key influences included his grandfathers, whose legacies in science and economics permeated family interactions. Paternal grandfather Edward Teller, the physicist instrumental in developing the hydrogen bomb, instilled storytelling, humor, and scientific curiosity through bedtime readings of Hans Christian Andersen fairy tales during Teller's ages four to eight, as well as discussions on physics and competitive bridge games. Maternal grandfather Gerard Debreu, who received the Nobel Prize in Economics in 1983, contributed to the household's emphasis on intellectual high standards, with parents bonding over experiences with such "high-energy, high-ego" figures. This heritage, steeped in science and letters, directed Teller toward early interests in technology and artificial intelligence, evident in his later academic pursuits.

Graduate Research and PhD

Teller completed his in and at , building on his undergraduate work in there. This program emphasized computational methods for problem-solving, including manipulation and search algorithms central to early research. He then pursued doctoral studies in at , where his research centered on techniques for algorithm development. His PhD dissertation, titled Algorithm Evolution with Internal Reinforcement for Signal Understanding and defended in December 1998, proposed a framework for evolving algorithms capable of processing diverse signal types and sizes without domain-specific priors. The work introduced internal reinforcement policies to guide , enabling self-supervised adaptation and addressing challenges in representation-search interplay within evolutionary systems. This approach demonstrated efficacy in tasks like face recognition and image classification, outperforming traditional methods by automating fitness case allocation and mitigating issues such as introns in program evolution. Key contributions included co-evolutionary models for programmer intelligence, where populations of programs and tests evolved in tandem to enhance robustness, and analyses of genetic programming's limitations, such as unnecessary code bloat reducing efficiency. Publications from this period, including "Evolving Programmers: The Co-evolution of Intelligent Rehabilitation" and "A Study in Program Response and the Negative Effects of Introns in Genetic Programming," underscored empirical validations through controlled experiments on signal processing benchmarks. These efforts laid groundwork for later applications in reinforcement learning and automated design, prioritizing causal mechanisms over heuristic approximations in AI optimization.

Pre-Google Career

Additionally, as co-founder and CEO of Sandbox Advanced Development, he oversaw prototyping and advanced R&D for aimed at future product lines for other firms, but details on specific outputs or exits remain limited.

Leadership at X (Formerly Google X)

Entry into Google and Role Establishment

In 2010, following successful entrepreneurial ventures including the founding of Cerebellum Capital, an AI-driven investment management firm, Astro Teller joined Google to help establish and direct its experimental innovation lab, initially known as Google X. This lab, conceived as a "moonshot factory" for pursuing high-risk, high-reward technologies, was overseen initially by Google co-founder Sergey Brin but quickly placed under Teller's operational leadership to focus on breakthrough projects beyond core search and advertising businesses. Teller's role evolved into that of "Captain of Moonshots," a title reflecting his responsibility for guiding ambitious projects through ideation, prototyping, and potential scaling or termination, emphasizing rapid iteration and tolerance for failure to achieve 10x improvements over existing solutions. In this capacity, he built the organizational framework for X, recruiting interdisciplinary teams of engineers, scientists, and designers while instilling a culture of questioning assumptions and prioritizing projects with massive societal impact potential, such as self-driving cars and wearable computing. By 2015, following Alphabet's restructuring of Google, Teller's leadership extended to the rebranded X lab under the new holding company, where he continued to define its mandate: incubating technologies that could solve global challenges through radical rather than incremental gains. His establishment of this role emphasized cross-disciplinary collaboration and resource allocation based on probabilistic success models, distinguishing X from traditional R&D by mandating explicit "killing" of underperforming ideas to free up capital for bolder pursuits.

Major Moonshot Projects Directed

Under Astro Teller's leadership as Captain of Moonshots at X, the lab advanced ambitious projects aimed at solving large-scale problems through radical technological innovation, with a focus on , iterative testing, and deliberate cancellation of unviable ideas. Key initiatives included autonomous vehicle development, which evolved into ; high-altitude balloon-based internet access via Project Loon; and drone delivery systems through . These efforts exemplified X's approach of pursuing 10x improvements over incremental gains, often resulting in spin-outs to independent companies or structured shutdowns to extract learnings. Waymo originated from Google's self-driving car project initiated in 2009, but under Teller's oversight at X—established around 2010—it scaled into a dedicated moonshot focusing on fully autonomous vehicles capable of operating without intervention. By , the project had logged over 20 million miles of real-world testing, leading to its graduation as an independent subsidiary in , where it continued developing Level 4 for ride-hailing and . 's advancements included from , , and cameras, enabling safe navigation in complex urban environments, and by 2025, it operated commercial services in multiple U.S. cities with millions of autonomous miles driven. Project Loon, launched in 2011, sought to provide connectivity to underserved regions using a network of high-altitude balloons navigating stratospheric winds via algorithms. Under Teller's direction, the project achieved milestones such as delivering emergency connectivity to after in 2017 and partnering with mobile operators for global coverage trials, with balloons maintaining station-keeping for up to six months. It graduated to an independent entity in 2018 but was discontinued in January 2021 after determining that technological and economic hurdles, including reliable and cost-effective scaling, prevented a viable despite valuable insights into aerial networks that informed successors like Taara. Wing, initiated around 2014, developed autonomous drone systems for package delivery, integrating aircraft design, computer vision for obstacle avoidance, and automated air traffic management to enable scalable urban logistics. Teller steered its progression through extensive testing, including over 100,000 flights by 2019 and commercial operations in Australia starting in 2019, where drones delivered items like food and medical supplies within 30 minutes over distances up to 12 miles. The project graduated as an Alphabet company in 2019, expanding to the U.S. and Europe, with regulatory approvals from the FAA for beyond-visual-line-of-sight operations and a focus on reducing delivery emissions compared to ground transport. Other notable efforts under Teller included early contributions to Verily, X's life sciences arm spun out in 2015, which tackled chronic disease management through wearables and AI-driven analytics, though it drew from broader initiatives. Projects like Makani, which explored via tethered kites generating up to 600 kW, were discontinued in 2020 after prototypes demonstrated feasibility but failed to achieve cost-competitive energy production at scale. This portfolio reflects Teller's emphasis on killing underperforming moonshots—over 100 by 2016—to reallocate resources, ensuring only those with breakthrough potential advanced.

Organizational Structure and Team Building

X maintains a fluid without standard org charts to accommodate the dynamic nature of moonshot , prioritizing adaptability over rigid hierarchies. Projects progress through defined stages, including Rapid for initial prototyping and feasibility testing, followed by the X phase for deeper validation, with an expectation that approximately 50% of projects will be terminated based on predefined kill criteria such as techno-economic viability. This portfolio-based approach mixes projects across hardware, software, industries, and timelines of 5-10 years, allowing to high-reward, low-probability efforts while learnings from failures into new initiatives, termed "moonshot ." Team composition emphasizes small core groups of 5-10 members, augmented by specialized in-house resources like and hardware labs, to foster and cross-disciplinary collaboration. Hiring targets "T-shaped" individuals with deep domain expertise paired with broad problem-solving abilities, alongside diverse backgrounds that include unconventional experts such as rocket scientists, pianists, and puppeteers to generate radical ideas and build resilience. Key selection criteria include fearlessness, humility, strong teamwork, and a growth mindset, as innovation is viewed as a "" rather than individual achievement. Under Astro Teller's leadership, team building cultivates a "responsibly irresponsible" culture that encourages for honest evaluation, with teams incentivized to tackle the hardest problems first, iterate rapidly, and actively seek to disprove their own ideas through processes like biweekly reviews every 3-6 months. Teller dedicates significant time—up to 80%—to mentoring and management, promoting and celebrating "frequent, messy, instructive failure" to accelerate learning, measured by "learning per dollar" rather than traditional milestones. This approach includes disbanding teams on underperforming projects to reallocate talent, ensuring focus on viable moonshots while maintaining a of audacious experimentation separate from Alphabet's core operations.

Innovation Philosophy and Methods

Core Principles of Moonshot Thinking

Moonshot Thinking, as articulated by Astro Teller, emphasizes pursuing radical solutions to through breakthrough technologies that achieve at least tenfold (10x) improvements over existing approaches, rather than marginal gains. This approach requires envisioning outcomes that initially appear unreasonable and coupling them with disciplined strategies to test feasibility, drawing inspiration from feats like the . At X, the moonshot factory, projects target massive problems solvable only via technological leaps, with teams incentivized to fail productively and pivot resources accordingly. A foundational principle is "falling in love with the problem, not the solution," which directs teams to deeply interrogate underlying issues before committing to technologies, avoiding sunk-cost biases in unviable paths. Complementing this is active idea killing: teams are tasked with rigorously disproving their most promising concepts early through rapid evaluations, such as pre-mortems and small-scale prototypes, to conserve resources—X reportedly terminates about 100 ideas annually while celebrating such "kills" to foster learning. Failure, far from being stigmatized, is normalized as essential progress; Teller advocates celebrating it to reduce fear of experimentation, enabling faster iteration toward viable breakthroughs. Another core tenet involves assembling "T-shaped" teams with deep expertise in specific domains paired with broad collaborative skills, promoting cognitive diversity akin to Apollo's interdisciplinary crews of engineers, designers, and even puppeteers for robotics. Perspective-shifting—reframing problems unconventionally—outweighs raw intelligence, as it unlocks creative solutions like harnessing high-altitude winds for energy. Projects operate under "responsibly irresponsible" guidelines, blending audacious 10x ambitions with fiscal discipline, including quarterly aggressive goals and portfolio balancing across timelines (5–10 years) and sectors to mitigate risks. This structure, via stages like the X Foundry for de-risking with small teams, ensures only scalable ideas graduate to Alphabet entities or spin-offs.

Embracing Failure and Rapid Iteration

At X, the moonshot factory led by Astro Teller, failure is not merely tolerated but actively encouraged as a core mechanism for accelerating , with teams incentivized to disprove their own ideas early through rigorous scrutiny and . Teller has emphasized that projects begin with deliberate attempts to "kill" them, fostering what he terms "intellectually honest failures" to avoid sunk costs on unviable concepts; for instance, teams that successfully terminate flawed initiatives receive public recognition, including applause, hugs, and sometimes bonuses, as this preserves resources for more promising pursuits. This approach integrates rapid by prioritizing quick, low-cost experiments to test assumptions, enabling teams to cycle through hypotheses at high speed—often building prototypes within weeks to validate or refute core technologies before scaling. Teller argues that such velocity in failing forward maximizes learning, as success provides limited insights compared to dissecting why an idea underperforms, a principle drawn from X's operational manual where is framed as a "powerful tool for learning" rather than a setback. By , this philosophy had already influenced X's culture, with Teller noting in public talks that dispassionate evaluation and ample funding mitigate the emotional toll of , allowing sustained without . Critics of traditional innovation models, which Teller contrasts with X's methods, often undervalue this iterative failure loop due to , but empirical outcomes at X—such as early pivots in projects like Project Loon—demonstrate its efficacy in refining moonshots toward feasibility. Teller maintains that without embracing and accelerating through failures, ambitious goals remain theoretical, underscoring rapid iteration's role in bridging radical invention with practical breakthroughs.

Balancing Risk and Commercial Viability

At X, Astro Teller implements a rigorous process to balance the high risks of moonshot projects with their potential for commercial viability, emphasizing early detection of flaws through and "learning per dollar" metrics to minimize sunk costs. Projects are evaluated not just on technical feasibility but on progress toward scalable, 10x-impact solutions that could sustain independent businesses or integrate into Alphabet's ecosystem, with teams instructed to tackle the hardest technical challenges first via low-cost experiments. This approach favors high-reward gambles—such as aiming for billions in long-term profits over guaranteed smaller gains—while de-risking investments by proving or disproving core assumptions cheaply. A core mechanism for this balance is the high rate of project cancellations, with X terminating approximately 100 initiatives annually as of 2014, often after initial tests reveal insurmountable barriers like excessive costs or issues. To encourage candid assessments without fear of reprisal, Teller's teams receive bonuses and celebrations for "successful failures" that yield valuable insights, fostering a culture where killing unviable projects is viewed as progress rather than defeat. This "hugs for killers" ethos, as described in X's internal practices, ensures resources are redirected to more promising efforts, such as those advancing toward commercial prototypes after initial de-risking. The 2021 shutdown of Project Loon exemplifies this discipline: despite technical achievements like balloon-based internet delivery over nine years, Teller cited the "much longer and riskier" path to profitability as grounds for termination, redirecting assets to adjacent technologies like Project Taara while acknowledging the opportunity costs of prolonged investment. Similarly, X has developed internal systems to forecast commercial potential once technologies are somewhat de-risked, prioritizing moonshots that address massive problems with viable paths to market dominance over speculative pursuits. Recent shifts, including spinning off projects into startups, reflect heightened scrutiny on financial returns amid Alphabet's broader cost controls, ensuring moonshot risks align with sustainable outcomes like Waymo's commercialization.

His presentations typically integrate first-hand accounts from directing high-risk projects, underscoring the necessity of coupling ambitious visions with disciplined execution to address global challenges. A landmark engagement was his TED Talk, "The unexpected benefit of celebrating failure," delivered on April 14, 2016, where he explained how X incentivizes teams with bonuses for promptly abandoning unpromising ideas, thereby accelerating knowledge gains and avoiding sunk-cost pitfalls that stifle progress in conventional R&D environments. In 2025, Teller keynoted the Rochester Institute of Technology's Academic Convocation for the Class of 2025 on May 9, framing graduation as completing life's "tutorial level" and exhorting attendees to cultivate creativity, practice gratitude, and boldly experiment in professional pursuits. At the Masters of Scale Summit on October 1, he explored how initially flawed or "bad" ideas serve as catalysts for innovation, advocating exploration of counterintuitive paths to uncover viable technologies. Earlier that year, on January 27 at SRI's PARC Forum during FutureFest 2025, he addressed the future of innovation, reflecting on AI's role in moonshot endeavors. Teller's thought leadership manifests in podcasts and interviews dissecting X's operational tenets. In a March 2023 Harvard Business Review podcast, he detailed balancing audacious risks with iterative "messiness" to yield transformative results, contrasting this with incremental corporate innovation. A September 12, 2025, NPR discussion revealed X's focus on preemptive technologies, such as power grid overhauls, to preemptively solve entrenched problems. In a May 2025 Roland Berger interview, he defined moonshots as targeting 10x improvements on massive issues while nurturing talent through autonomy and , warning against complacency in addressing humanity's thorniest challenges.

By October 2023, vehicles had driven over 20 million fully autonomous miles on public roads, enabling commercial services in cities including Phoenix, , and . Wing, X's drone delivery project initiated in 2011, transitioned to an independent company in 2019 after demonstrating reliable package transport via autonomous drones. As of 2023, operated delivery services in , , and parts of the , completing over 300,000 deliveries with a focus on small payloads under 2.5 kilograms. Verily, stemming from X's life sciences efforts started in 2013, became an independent life sciences company in 2015, targeting precision health technologies such as wearable devices for chronic disease management. Verily's projects include the Verily Study Watch, approved for clinical use, and partnerships yielding FDA-cleared tools like continuous glucose monitors integrated with systems by 2020. Chronicle, X's cybersecurity moonshot launched in 2014, graduated in 2019 as an independent business providing cloud-based security analytics. It processed petabytes of enterprise data daily to detect threats, later integrating into Cloud's security offerings while maintaining its core engine. More recent graduations include , an X project using to optimize crop yields, which advanced prototypes for automated field scouting by 2022, and Taara, a technology spun off in March 2025 to deliver multi-gigabit broadband via links, tested in and for connectivity in underserved areas.

Influence on Broader Tech Ecosystem

Teller's dissemination of moonshot thinking—defined as pursuing radical solutions to massive problems via breakthrough technologies—has shaped innovation strategies across the tech sector. Through keynote addresses, such as his 2016 TED Talk emphasizing the value of "celebrating failure" to accelerate progress, and interviews in outlets like WIRED, he has advocated for cultures that reward rapid experimentation over aversion to risk, influencing how startups and corporations approach R&D. This philosophy, honed at X, has been cited by business leaders as a template for balancing audacious goals with iterative learning, evident in the proliferation of "10x thinking" frameworks at firms like SpaceX and in venture capital pitches prioritizing transformative impact over incremental gains. Technologies incubated under Teller's oversight at X have rippled into broader industries. Waymo, evolved from X's autonomous vehicle efforts initiated around 2009, achieved Level 4 autonomy milestones by 2020, enabling robotaxi services in cities like Phoenix and San Francisco as of 2024, which has accelerated regulatory discussions and competitive investments in self-driving tech by entities including Tesla and Uber. Wing's drone delivery platform, tested commercially in Australia and the U.S. since 2019, has demonstrated scalable last-mile logistics, prompting advancements in aerial delivery by competitors like Amazon Prime Air and Zipline, thereby expanding the drone ecosystem's commercial viability. X's recent pivot toward spinning off projects as independent startups with external funding, announced in 2023, further extends Teller's model to the entrepreneurial landscape. Examples include Mineral's precision agriculture tools, leveraging AI for crop optimization, which integrate with global farming tech stacks and attract venture backing, fostering a hybrid of corporate R&D and startup agility that other labs emulate. This approach, per Teller, prepares innovations for market realities beyond Alphabet's subsidies, influencing how tech giants like Meta and Apple structure their exploratory divisions to seek outside capital for high-risk ventures.

Criticisms and Controversies

Financial and Efficiency Critiques

Alphabet's X laboratory, under Astro Teller's leadership since 2016, has faced scrutiny for its substantial annual expenditures relative to commercial outputs. In 2016, the division received over $1 billion in funding from , with the majority allocated to projects like self-driving cars and , contributing to operating losses exceeding $3.5 billion for Alphabet's non-core segments that year. Analysts estimated that up to 10% of Alphabet's R&D budget, or approximately $650 million, was directed to X in 2015, correlating with EBITDA shortfalls amid investor demands for fiscal discipline. Critics have highlighted inefficiencies in project commercialization, noting persistent challenges in transitioning moonshots from prototypes to viable products due to internal and talent attrition. High-profile departures, including engineers from the unit who founded (later acquired by ), underscored difficulties in scaling amid "red tape and internal politics," as reported by former employees. analysts, such as Ben Schachter of Macquarie Securities, have questioned the return timelines for initiatives like —projected for $3 billion to $11 billion in sales by 2018 but ultimately phased out—and , amid opaque financial disclosures that fuel about ROI. Recent developments reflect heightened financial pressure on X's model. By 2024, intensified scrutiny on the lab's budget—previously in the hundreds of millions annually—leading to staff reductions of dozens of employees and a pivot toward external investors for project funding, signaling internal recognition of unsustainable spending without proportional breakthroughs. Observers have argued that despite spin-offs like , X's track record of numerous cancellations (e.g., Project Loon, ) yields few consumer-facing products, prompting claims that "you can't spend that much money and not produce anything." Teller has countered by framing X's mandate as akin to returns, emphasizing long-term potential over immediate efficiency, though detractors contend this overlooks opportunity costs in a competitive tech landscape.

Project Failures and Overhype Allegations

Several high-profile projects initiated under Astro Teller's leadership at X have been discontinued after failing to achieve technical or commercial breakthroughs. Project Loon, aimed at providing internet access via high-altitude balloons, was terminated on January 21, 2021, with citing an unsustainable business model despite years of testing and partnerships. Similarly, Makani, which sought to generate wind energy using airborne turbines tethered to kites, was shuttered on February 18, 2020, as the technology proved insufficiently scalable for cost-effective power production. Other cancellations include efforts in and autonomous cargo ships, which were abandoned after early prototypes revealed fundamental engineering limitations. In 2015 alone, X teams proactively killed over 100 experimental investigations to redirect resources, a practice Teller has publicly incentivized through bonuses for early termination. Critics have alleged that X's moonshot pursuits under Teller generate excessive hype relative to tangible outcomes, portraying ambitious visions that often evaporate without broader impact. , an early X project, was criticized for overhyping its capabilities in 2013, leading to public backlash over and usability issues before its consumer pivot failed commercially by 2015. Teller has acknowledged this tendency, cautioning against the "Silicon Valley hype machine" that mythologizes visionary innovation, yet detractors argue X's narrative of transformative potential—amplified through TED talks and media—sets unrealistic expectations while masking a track record dominated by cancellations. For instance, despite claims of rapid yielding systemic learnings, the lab's emphasis on "celebrating failure" has been questioned as a rhetorical shield for projects that consume significant capital without proportional spin-offs or technologies reaching market. Insiders and former X personnel have leveled allegations of structural inefficiencies contributing to these failures, suggesting Teller's fail-forward culture inadvertently fosters dawdling and bureaucratic drift rather than agile progress. Reports from 2016 indicate high turnover and frustration among staff, with the lab described as evolving into a process-heavy entity unable to graduate projects effectively beyond outliers like . One analysis noted delays in key initiatives, such as self-driving technology, attributing them to internal mismanagement under Teller's oversight. While X defends early project kills as cost-saving measures—potentially avoiding billions in sunk costs—skeptics contend this approach reflects overhyped ambition without rigorous upfront feasibility assessment, leading to a portfolio where most efforts yield or pivots rather than revolutionary deployments.

Ethical Concerns in Ambitious Tech Pursuits

Critics have raised concerns regarding projects developed under Teller's leadership at X, particularly those involving pervasive and capabilities. Google , an early X initiative, featured a built-in camera that sparked widespread apprehension about unauthorized recording in social settings, contributing to public backlash and incidents such as assaults on wearers. The internal "Selfish Ledger" concept, originated by X's design team in 2016, envisioned aggregating comprehensive user data across devices and generations to nudge behaviors toward societal goals like , but lacked explicit safeguards against invasions or autonomous , evoking fears of corporate-driven social engineering. Although presented as rather than a product roadmap, the proposal underscored ethical tensions in X's ambitious data-centric innovations. Teller has addressed such issues selectively; regarding Glass, he suggested privacy worries were exaggerated relative to the device's potential, attributing much of the failure to premature rather than inherent flaws. Broader ethical scrutiny of X's moonshots centers on from rapid scaling of transformative technologies, such as efficiency gains paradoxically increasing resource consumption via effects like the . Critics, drawing from thinkers like , argue that an obsession with technological speed and magnitude risks overlooking localized harms or exacerbating inequalities, potentially prioritizing profit-driven disruption over equitable outcomes. Teller counters that X mitigates these by rigorously testing prototypes early to uncover risks, framing ethical responsibility as integral to pursuing purpose-aligned innovations at the nexus of impact and viability. In domains like autonomous systems and AI—core to projects such as —concerns persist about accountability for errors, including algorithmic biases or safety lapses that could endanger lives, alongside socioeconomic disruptions like widespread job displacement in transportation sectors. These amplify calls for anticipatory in moonshot pursuits, where X's emphasis on high-risk experimentation invites debate over whether internal safeguards suffice against systemic externalities, such as geopolitical dependencies on Alphabet's tech dominance. Despite Teller's advocacy for a hopeful, proactive stance toward to avoid self-fulfilling dystopias, the opaque nature of X's operations fuels skepticism about unaddressed moral hazards in chasing breakthroughs.
