No kidding. You want to keep a guy like Carmack in the family in whatever capacity you can, because he carries such deep respect in the industry. It was a stupid thing for ZeniMax to burn that bridge.
I can bet that many people would willingly taken pay cuts (or more-likely skipped on pay bumps) to work for a team led by Carmack.
Almost all of the other pop-culture figures in game development such as Todd Howard, Kojima and the like are designers, producers or story writers.
Carmack is the only one that is a proper coding guy.

Maybe Carmack comes back to lead Windows mixed reality ¯\_(ツ)_/¯ and PCVR ? True wishful thinking right here.
It'd be very interesting to see if his return to Id might spark some changes :)
