I have 32GB Ram in my Asus with Ryzen 7 chip. I can tell you that it may feel a waste, but if you need it for anything it is avaliable.
I do mostly python development, movies, surfing and zoom, with at least 4 applications running simultaneously. My Ram never exceeds 10GB, using KDE instead of gnome. When i compile some applications it may exceed this a bit, but that was the point of my rig. The processor rarely has cores working above 10% (once applications are loaded) and it remains lightning quick. Anyone with less memory intensive use shouldn't need more than 16GB. 32 ensures you are future proof for a bit. Anything more than that is overkill and unnecessary for average users.
