> We did not manage to solve even one none technical problem since we came down the trees. But that's nothing unexpected actually given we're a horde of apes. I'm old enough to know that nothing will ever change as we had already more than enough time to easily mange at least some "humanity scale" issues by now. But we as a species are seemingly bound to our ape nature. Counter-example: The use of slavery as an energy source replaced by the use of electricity as an energy source. When you want to listen to music, you open up Youtube (or Spotify, or your carefully curated collection of FLAC files, or whatever) and press play. When Romans wanted to listen to music, they would tell the slaves to pick up the instrument and start playing. That's a significant change, IMO. EDIT: also, written language went from non-existant to 8 billion humans and 86% of them can read in a few thousand years.
