> We used to have 64MB and that was plenty.

Bullshit. It was cramped and I wasn't able to do half of what I was wanting to actually do. Maybe it was plenty for your usecases, but such a small amount of memory was weak for my needs in the late 90s and 2000s. 64MB desktops struggled to handle the photo manipulations I wanted to do with scanned images. Trying to do something like edit video on a home PC was near impossible with that limited amount of memory. I was so happy when we managed to get a 512MB machine a few years later, it made a lot of my home multimedia work a lot better.
