Selfishness may have been selected for tens of millions of years ago in our evolution, but as pre-humans became social animals it’s clear that selfless or other-centric thinking became strongly selected for as well. You otherwise couldn’t have a species that’s almost entirely other-dependent, throughout the whole life but especially for the first 10-15 years of it.
Humans can’t sustainably exist outside of a society.
I was impressed by how streamlined and intuitive EndeavorOS (with Plasma) is out of the box when I threw it on a friend’s computer. Will probably switch to it myself shortly.
