I second Richard Sharpe, that there are many mistakes made within the hypothesis of the thread.
first of all, I can hardly find a connection between your headline and the following explaination. what has intelligence in common with those causalities? would you mind to elaborate on that?
I have the impression, that there are two topics oddly mixed up with eachother.
Intelligence might be a dead end for the personal evolution. It might get in conflict with the instinct, which may cause destructive behaviour.
Agriculture -> Jobs -> Poverty
Logic -> Computers -> AI -> Enslavement of Humanity
Electricity -> Fossil Fuels -> Climate Change
how do jobs cause poverty?
I strongly doubt that enslavement of humanity will be caused by AI. even though hollywood propagades a different view, for obvious reasons.
Electricity can also be provided by solar energy etc. and the effect of CO2 on the climate is still controversial.
Climate Change: It works subtly enough for many to not notice what's happening, unlike a war scenario where we'd quickly see the damage being caused and stop.
*subtly [..] to not notice what's happening* - cause there is barely happening anything at all. climate change takes at least more than centuries. so no worries. Furthermore we still live in a glacial.
anyways, I doubt that climate change will lead to the extinction of humanity. maybe to the reduction of population in bangladesh.
War -> Society. Without war, there is no society because society is built on the principles of war. Without society, there cannot be war.
even if without society, there cannot be war, why should society be built on the principles of war? I would rather say it is built on the principles of economics.
At least, the evolution of population numbers shows that humanity isnt going to extinct very soon ...
