This is just DRAM hysteria spiraling out to other kinds of hardware, will age like fine milk just like the rest of the "gaming PC market will never be the same" stuff. Nvidia has Amazon, Google, and others trying to compete with them in the data center. No one is seriously trying to beat their gaming chips. Wouldn't make any sense to give it up.
It's not related to the DRAM shortage. Gaming dropped to ~10% of Nvidia's revenue a year or two ago due to AI and there was controversy years before that about most "gaming" GPUs going to crypto miners. They won't exit the gaming market but from a shareholder perspective it does look like a good idea.
if it were up to them, cuda would be a money losing initiative that was killed in 2009
