@sjmulder meanwhile I found a video just the other day that turns some old PowerMacs into fully usable modern machines just installing modern Linux on them, they're as good as new, meanwhile modern macOS would have no chance running on them even if it still supported PowerPC

and from my own personal experience: had a Lenovo G50-45 which was... not the fastest laptop of 2015, to say the least

Windows 10 struggled to keep a steady framerate on the desktop by 2018, Arch Linux with KDE Plasma would still purr on it like it was brand new by 2020, still handled the older games I played when I got it the same as it did brand new

but sure, hardware just degrades in performance and software definitely doesn't make a mockery of any performance improvements hardware still gets generation to generation
