In my experience, the average PC gamer upgrades their PC with a few new parts every few years, and even that isn't certain. Replacing the whole thing every 5 years seems atypical, that's a lot of money to be throwing around (particularly when many PC gamers are in it for the long-term economy.)
The average PC gamer is, of course, not the average computer user which is far more likely to be using a generic laptop or smartphone.
Which is all to say, I understand why we want modularity, but - for most computer users - a much more necessary path forward is a reimagining omaterials recyclability.
I think the average computer user is even more likely to be using old hardware than a gamer. The average Joe browsing facebook could be perfectly content with a 15 year old computer. Gamers at least are pressured to periodically update their hardware by the appeal of games that demand more than their old computer can provide.
