Speaking as someone who did have a computer from 10 years ago as the main computer until a year ago, no, it's very realistic. At no point did I come across a game that was "my computer isn't powerful enough to play this game." Even compiling large projects is less helpful than you'd think: a clobber build is still context-switch-while-it-finishes, and incremental builds usually don't build enough for all of the extra threads to be worth it.

Sure, maybe my computer might have screamed at me if I tried to watch AV1 or H.265 4K video, but... my computer is 10 years old and so is my monitor, so I don't have a 4K monitor. And, quite frankly, I don't see the point upgrading from 1080 to 4K.
