Not everyone lives in the first world. Not everyone has a new computer.
It is this sort of hubris that likely explains my feeling that personal computing has regressed in many ways for the average individual over the recent years. I'm not talking about the hacker who can run surf+i3 on their cyberdeck, I'm talking about the person with an 8-year old computer bought on sale or a 4-year old smartphone.
RAM is only cheap because people don't waste it. If every application was written with Electron or every executable was a Java program (including CLI commands) you would cry and beg for more memory efficiency.
You can get 16GB for $52 on Amazon. That 700MB is equivalent to $4.64 one-time payment.
There are more important things to worry about, seems to me.
