> Carmack is a life-long game-developer (always more focused on "technical" aspects of gamedev, like graphics), and now basically a rich celebrity, who can indulge himself by something as grand and abstract as "working on AGI" (since 2019). He also started a rocket company and was a big part of making VR workable with reprojection techniques and other innovations (some of them may have had precedent but so did Doom, he and others got it all working in useable form this time, like Doom (Ultima Underworld was a bit slow and had to be run in a much smaller fraction of the screen)). Beyond just pure rendering, he also created the first usable megatexturing/virtual texturing, now used about everywhere, which is almost more of a data management problem. It maybe wasn't that great until SSDs, but he knew that and put out an early mindblowing iphone version using the solid state storage and integrated cpu/gpu memory as well.
