I'm sad that Carmack decided to (as I understand it) focus away from LLMs because they're "already getting enough eyes" -- it feels like he wants to make a novel paradigm shift kind of contribution, but his magic power has always seemed to me to be a capability of grasping a huge amount of technical depth in detail, and seeing past the easy local optima to the real essence of the computation being done, and finding ways to measure and squeeze everything out of that.

Carmack could possibly get us realtime networked stable diffusion text to video and video to video at high resolution, maybe even on phones. It will probably happen anyway, but it might take 5+ extra years, and there'll probably be a ton of stupid things we never fix.
