Honestly, I don't agree with this. The evolution of computers seems to have sharpy dwindled, to the point that I regularly switch between a 2016 Lenovo and an 2021 Framework and hardly notice the difference, at least performance-wise.
And so I was eyeing the Framework 16 announcement, but I'm not sure I'll be happy with the ports situation (especially when a Framework costs ~double what I'd otherwise spend). Luckily, Beyond All Reason (RTS) at my skill level is still playable even at the 10~20 fps that I get near the end of a game.
swap hats, and go into video/photo editing, and the old box feels like a boat anchor to the process.
swap hats again, and start browsing the web, now it's a mixed bag depending on how bloated the devs made the site. my 2019 MBP still handles any and all video streams. it plays back my 4k edits just fine too.
