and finally
learn what
it is to be civilized.
How many centuries it will take for humanity to reach that? Legit question. Looks like (based on history) humanity does not learn that. The same things (wars, killings, crimes, and the destruction of planet Earth) are going on since ages.
Despite what we hear in the news (as a whole they like to instill fear and hatred), statistically, we live in a far safer world that we did 100 years ago. As long as there isn't some widespread natural or manmade catastrophe I expect that trend will continue. A.I. becoming sentient will be humanity's next big challenge, I think. That should happen within the next 10-30 years.
