John Carmack joins Oculus VR as Chief Technology Officer (CTO). He brings his expertise in computer graphics and software engineering to the development of virtual reality technology.

Facebook (now Meta) acquires Oculus VR for $2 billion. Carmack continues to lead the technical development of Oculus' virtual reality hardware and software.

Carmack becomes increasingly focused on optimizing mobile VR experiences, pushing the limits of mobile hardware to deliver high-quality virtual reality on devices like the Samsung Gear VR and Oculus Go. He advocates for efficient coding practices and innovative rendering techniques to overcome the limitations of mobile processors.

Carmack transitions to a consulting CTO role at Oculus, allowing him to dedicate more time to research and development, particularly in the area of artificial general intelligence (AGI).

Carmack announces his departure from Meta, citing disagreements over the company's efficiency and strategic direction. He expresses frustration with the slow pace of development and the perceived lack of focus on core VR technology. He states a desire to focus on his AGI startup, Keen Technologies.
