Actually I would say many, many need more than 8GB. And, a lot of power users who think 16GB is enough could benefit from 32GB if they really multi-task or use demanding applications a lot.
Idle - 1 tab browser is all that's open - 6.5GB used :

At this point, 8GB will be swapping. If anything, what I'm doing is a light load for an office worker. For a more advanced business user, well it's not unusual to see them with a dozen spreadsheets and half a dozen PowerPoint or word docs of significant size open, along with java laden productivity web sites. Sometimes 16GB isn't enough.
That's Tiger Lake on the desktop. I really like AIOs and now that GPUs cost too much to be practical for most people, a setup like that is about the best deal going.
