Well... here's the thing. 99% of people just don't need more than 16 or 32 GB of RAM. I don't do any video editing, but at any given time, at work, I have several VMs open, Chrome or Firefox which tend to hog memory, a couple of development environments (usually PyCharm, VS, Android Studio or Eclipse), and several more lightweight stuff - IPython, Sublime Text and a couple more.
At max, if I set the VMs to too much RAM, this adds up to about 16 gigs of RAM. 32 gigs? No way I could get up to that. Maybe if I had an itch to keep 30 tabs open in Chrome instead of my usual ~6.
In the past with weaker computers, I used to ration my RAM. Haven't needed to do that in the last couple of years. Same goes for CPU - anything that's not really computationally expensive just doesn't take a long time to run nowadays. We've more or less reached the point where computers are good enough.
