Please stop this nonsense. Come back a year from now and do the same check. In fact do the same check now and compare steam stats to XB1 and PS4.
We heard the exact same thing last gen, didn't we? "Just wait until the devs optimize their code and squeeze everything the consoles have to offer!" - and yet, the launch titles didn't age at all compared to games that are being released today, we can even argue that TO1886 and Ryse are still the best looking games of both current-gen consoles.
The baseline is set really high this time around I'll give you that, but then again, 30FPS? We saw that this gen, where an ordinary 2C/4T CPU was running the same games at twice the framerate, and as a matter of fact still does, in 2020. So if you are also willing to also limit your PC experience to just 30FPS, I think it's safe to say many many people are already set for the upcoming generation.
Not to mention 4K on PC is basically non-existent unless you hook up your PC to UHD TV, so the vast majority people will play at 1440p anyway (if not 1080p), which is half as demanding as 4K. So again, with the same/better specs, at 1080-1440p30, people with today's gaming rigs should be way more than fine in the entire upcoming generation.
SSD turned out to be a gimmick (who would've thought!), the only game that's so far really build around it is R&C, which is not available on PC anyway, while Kena for example which looks better takes only 25GB space, many people have just as much if not more RAM than that, I have been saying this over and over in the past months, that PCs don't rely so heavily on streaming as consoles because they can actually store way much more data in the operating memory. Not every game will have trans-dimensional/world transitions, most won't actually.
We saw many many upcoming next-gen games already, and it's hard to argue that other than bumping the resolution to 4K from 1440p, and the settings to Very High-Ultra from Medium-High, there's barely any difference between current and the upcoming generation. IMO as of now,

turned out to be spot-on with his predictions than next-gen consoles = current-gen PCs.
Maybe something will indeed change in the future, nobody knows, but then again, being able to swap individual components is one of PC main advantage, if someone will be really lacking CPU or GPU power, RAM amount, SSD speed, they can add/change just that, instead of needing to buy an entirely new system.
