I think I meant older cpus are quietly deprecated due to such bugs (overeager speculative execution or whatever). There are many workarounds in the Linux kernel for such flaws, but the "oldest" Linux kernel still actively maintained (on kernel.org) is 4.19 from Oct. 2018. I'm sure distributions can still patch other kernels if needed.

But overall it's sometimes hard to find sympathy for old or weak tech. If it isn't actively sold, maintained, or doesn't receive security fixes (or microcode updates), some people refuse to care.

In a perfect world, any tech that could work should be potentially good enough (and not worthy of scorn).

I saw someone on Twitch stream Quest for Glory (EGA) via DOSBox. As you know, VGA was vastly more popular and easier to program. Still, EGA works on more machines and 320x200x16 colors is still "good enough" for some things. My point is we don't always forcibly have to use the "latest greatest", even if everyone else seems to be doing it. (We may both be preaching to the choir here.)
