A lot of my Steam games work flawlessly with Linux but others will just silently fail to launch and it takes hours to properly diagnose and fix, which isn't what I'm after when I get some time to play games.
Nobody can see it, because those who want it will mostly make do with Windows.
Personally, I spend 98% of my time in Linux, but I dual-boot just for the sake of the few games I like that need Windows to run. If not for that, I'd have dropped Windows years ago.
However that niche is way too small to be worth it.
Nothing to do with prophecies though.
Not every demand can be fulfilled, no matter what.
For me, the gaming situation on Linux has become tolerable enough that, in comparison to Microsoft's Windows 10 bullshit, it is no longer a barrier. However there are several other barriers that are unlikely to be dealt with any time soon.
