It is not a question of want. Gaming will exist in some form so I am simply uncertain what you are concerned about.
Can you elaborate a little? What, exactly, is your concern here? That you won't have nvidia as a choice? That AMD will be the only game in town? That gpu market will move from duopoly ( for gaming specifically ) to monopoly? I have little to go on, but I don't really want to put words in your mouth based on minimal post.
I want a local gaming machine that I control.
Not a locked ecosystem console or a streaming service with lag!
I think if nvidia leaves the market for AI, why wouldn’t AMD and intel, with the memory cartel. So DIY market is gone. That kills lots of companies and creators that rely on the gaming market.
It’s a doom spiral for a lot of the industry. If gaming is just PlayStation and switch and iGPUs there is a lot less innovation in pushing graphics.
It will kill the hobby.
