Imagine next gen consoles, suppose they stick with AMD. Then every game studio and game engine studio is going to love flinging some AVX-512 around. Developers will get more experience with it, any game that runs on PC and Console is going to look slow on PC if you have intel cpus with bad support. More libraries and tools will get created that people will want to use.
Next-next gen consoles are probably still a good 5+ years away. AVX-512 for consumers will either have already become "a thing" or it'll be dead & buried by then.
Adoption could accelerate quick!
