>Future hardware
Interesting wording. That could mean anything from consoles to VR headsets.
windows mixed reality got axed december last year. there won't be anything VR besides something third party, who already have their own ecosystem, and would need support from MS to do so which would also cost money I doubt they're willing to spend.
While this was true at one point, its simply no longer the case. Consoles are just limited PCs now. And PC gaming isn't even that hard to get into at this point, compared to what it was in the 90s or even the 2000s and early 2010s. You can just buy a pre-built PC specifically made for "living room" use. PC gaming is no harder to get into than console gaming now. Exclusives really are the only selling point now, and most people only stick with consoles out of inertia or misplaced brand loyalty. Nintendo is the only console manufacturer worth looking at specifically because of their exclusive library.
you already answered why PC isn't an alternative: normalfags don't want to "build" their console.
they want to go out (or order online) "personal computer 6", which is better than the last model "personal computer 5", made obvious because the number is higher. then they want to plop it below their tv, hook it up (if they can even manage that much, seriously), click a few buttons, pop in a disc (for now) and play.
they're not gonna learn specs, then build it themselves or ask someone else, and afterwards set it up or deal with it. keep in mind most normalfags deal with computers in their line of work, for them it's synonymous with "work", not playing games.
PC will never be able to compete with that on a technical standpoint alone, besides the branding issue. the closest you'll get is something like the steam deck, because again it is it's own "brand" while easy enough to use, but still not as idiot proof as your average consoles.
however the deck has the same issue as the switch, in that there isn't any AAA goyslop they see in ads (otherwise they don't know about any exclusives since they don't follow gaming news) or fifa/cod, either because the hardware is too weak or it's not working ootb on linux.
steam machines were the right idea (just bad execution) and a too early, in theory it should be possible to replicate the mobile landscape where people don't care what's in them or specific vendors, if it's too slow it simply gets replaced, but that would require a lot of work no on is really willing to do and spend the money on besides valve.
