It’s easier to build a PC in 2023 than it was in 1993. Modern motherboard’s typically don’t require separate cards for sound, network and video (unless you’re gaming). It’s mostly integrated now and you don’t need hours manually manipulating jumpers and trying to affix terribly designed IDE cables now replaced with SATA. I’d much rather work on repairing my modern PC vs trying to troubleshoot a Compaq 486 20+ years ago.
I think the automotive analogy is relevant, some think using technology means they understand it. I’m a pretty good driver, but it would be unwise to ask me to repair your car’s transmission. My grandmother spends more time on her computer glued to Facebook than I spend using my computer on a given day, but I’m not asking her to build my next gaming rig.
