I’ve been using Linux since RedHat 4.2, and for a number of years in the early 2000’s as a desktop. Since then it’s mainly been as a server, and I just recently got back into running it as a primary desktop.
The “it’s always been that way” argument is stupid and you should know better.
Humans are even more incredibly resource intensive. Are you doing your part by not breeding? Judging by your post history I’d say you’re well on your way, good show!
