Really? As long as I've been building my own PCs, (2011) it's been fairly plug and play, with no more than basic knowledge or research required, and I would hardly say over a decade is "a few years". Also, technically speaking, techy people ARE laymen unless they're literally IT/design/engineering professionals as well. I agree that it's becoming much easier to find out what parts are optimal for a budget and put together builds in general, but idk your post comes off as very gatekeepy and a bit cringe.
