Carmack hasn't produced anything genuinely noteworthy after leaving id software, if we are being frank. His work at Armadillo aerospace was more akin to hobby, not really leading anywhere, a VR stint at facebook, again, is difficult to gauge at how large his personal contribution was, and this new AI thing is likely end with him leaving the company, again. Carmack is an amazing engineer, a genius even, but either the age of the individual contributor creating the entire thing from the ground up is over, and he's bored of it, trying to find a niche where this still works, or he is exploring the areas in which to apply his curiosity. What I'm saying is that his current productivity or lack of thereof isn't a marker of how AI is productive (or not) in general
