Building a machine that does everything is coming to a household near you! The rest of us, well we’ve been building custom gaming machines for one or two games for a long time.
The tooling is just getting better everyday. I don’t think Windows gaming will ever die but I think the experience has gotten bad enough that people have begun seeking alternatives. If this wasn’t true I don’t think that the SteamDeck would be so successful.
With that being said, I don’t tell everyone to try Linux. I do think that Linux is good for gaming but just hard to use for most gamers. I’ll probably buy a steam deck OLED in March just to “do my part” even though I have far too many custom machines and not enough time to enjoy playing the games.
