I'm not nearly so sure of that. The barriers to entry in the GPU space are gargantuan. Assembling a team capable of designing a competitive GPU, getting that design done and fabbed, coding drivers with good stability and performance, all that is a huge task that would take an absolute minimum of 5 years and a budget running to several hundred million.
if you're a tech investor are you going to put your money into a $2.5bn market that Intel, with all their resources, has barely been able to impact despite spending stupid amounts of money? No, you wouldn't; you'd look for a startup designing an AI chip instead. Lower barriers, 30-50x bigger potential market. Same reason why NVidia and AMD don't really care about gaming any more, AI processors take much of the same skillset and resources but offer a bigger potential payoff.
And I'm not even going into the financial insanity of using precious fab allocations for GPUs that make almost no money. Unfortunately we gamers are going to get crumbs from the AI table unless the bubble bursts.
