Honestly, we don’t know. Average laptop screens haven’t had any major improvements since IPS, so I think the screens have longevity. RAM and processors are more focused on lower power nowadays. Framework has already shipped “drop-in” replacement boards, and their whole company is based around that idea.
If I had the money and i could afford to wait, I’d be willing to take a bet on Framework. I think the frame of the laptop will hold up as well as any other, but it’s only been a few years so who actually knows.
Laptops from 6 years ago hold up well enough, except the batteries and main boards, if I could have replaced my old main board with a more modern processor and gpu I never would have had to upgrade.
