>Windows 10 will die this October. Steam will stop working on it.
Steam will keep working until Chromium drops support at which point it will still keep working for a while with no guarantees, just like on Windows 7. Valve isn't going to flip a kill switch for no reason.
>And Linux still sucks
It does, actually, unless you're willing to compromise and learn how to use something new. Linux works for me but I don't play online games so my opinion doesn't matter. You won't switch to Linux because it's not for you. You will upgrade to Windows 11, 12, and so on, and you will be "happy".
