PC gaming was always a niche market relative to the consoles, and it will probably remain so. But also, it's never looked better, had such a great selection (especially indie games), or been this affordable (between Gamepass, GeForce Now, and various publisher subs). For like $30/mo you can play many of the latest amazing games on max graphics without owning a GPU at all.
I hope, like servers, more and more of this moves to the cloud. It doesn't make sense to run much of this workload locally when they can be more efficiently managed and shared in data centers anyway, with better power and cooling management than most home PCs could have.
