My gaming PC has 32GB. Don't see a reason to have any less.
I regard 16GB as a minimum spec for a laptop, but have had to settle for less than minimum spec on my M1 (as I can't justify the steep second hand price jump).
I do like having a lot of stuff going on at the same time. For example "Preview" is using about 3GB due to many PDF manuals being open. (And it's so sh*t at releasing memory.)
