Carmack said in a Facebook post, “I will still have a voice in the development work, but it will only be consuming a modest slice of my time.”
He added that the plans to focus on artificial general intelligence, writing, “As for what I am going to be doing with the rest of my time: When I think back over everything I have done across games, aerospace and VR, I have always felt that I had at least a vague ‘line of sight’ to the solutions, even if they were unconventional or unproven. I have sometimes wondered how I would fare with a problem where the solution really isn’t in sight. I decided that I should give it a try before I get too old.”
ZeniMax acquired Id in 2009, and Carmack left that company to assume the CTO role at Oculus in August 2013.
Facebook acquired Oculus for roughly $2 billion in July 2014.
