Does anybody else find Musk's concerns about AI wildly overblown? Just to pick one example, does anyone really believe that autonomous weapons--most of which have yet to be developed--will be more dangerous than nuclear weapons are now?

I've seen this movie!

It's called "Colossus, the Forbyn project"

Highly recommended

if an AI figures out sending out an ICBM is the best solution it's more likely to use it than a human.

...if we let it.
