There is already something like that and it's called "consoles". Also, steam comes with a lot of bloatware and some things that you could easily call spyware as well.

If you want the most of your hardware, I suggest installing arch linux without gui and only running games via gamescope (for example).

Are you aware that SteamOS is a Linux operating system? Sure you can replace another variant of Linux in your computer with it but you'd still be running a Linux operating system. Also even if nothing else is installed on SteamOS, Steam client, integral part of SteamOS, will gather telemetry from your computer.

Linux is great for old computers but Newly store bought computers dont work on Linux. Its the kernel that has all the drivers. thats why windows is king.

I was hoping for that too when I considered replacing Windows, but so far, reviews show that it's terrible for PCs at the moment.
Hopefully, Valve will improve their OS for PCs in the future

That's a false narrative. There are some hardware issues, but I have yet to find a laptop that I couldn't wipe clean of Windows and install Linux.

SteamOS is more of a specialized Linux distro designed with the Deck in mind. It's not a whole new OS.

You could install a stripped down Linux distro, install Steam on it, and run it with Big Picture Mode. That's basically SteamOS. SteamOS has specialed tweaks for the Deck hardware, but the underlying OS is still Linux.

Steam OS IS Linux.

Even consoles are running modified versions of existing OS. Xbox has a highly modified version of the Windows kernel running. PS5 is running a modified version of FreeBSD, which is Unix-like. The Switch is probably the closest to a bespoke OS for that hardware, but it still has bits of code from Android and FreeBSD, and the Nvidia driver it's using for the Tegra chip is similar to the Linux driver.

This is verifiably wrong. New and old computers run Linux just fine. Also the drivers built into Windows are pretty much always out of date, so you need to download and install the latest ones for your GPU and chipset. You feel free to use Windows though if that's what works for you. I won't try and tell you not to.

Why reinvent the wheel when Linux already does that for them? That's why they build SteamOS on Linux, instead of trying to invent some new kernel.

Uhm the STeam OS is Linux OP.
Like it's literally just a branded build of linux. And there are better linux builds out there.
WHat's standing in the way really is the fact that it needs to run actual productivity software to be viable in the market.
