Yeah, modern computers often feel like a scam. Obviously, some things are faster and obviously, we can calculate more complex problems.
But so often, programs are only optimized until they reach a level of "acceptable" pain. And especially with monopolistic, commercial software that level is close to infinity, because well, it's acceptable so long as customers don't switch to competitors.

Either way, the slowness that was acceptable twenty years ago is generally still acceptable today, so you get much of the same slowness despite being on a beefier PC.
