Instead of replacing all human drivers with robots why not redesign things so that we don't have to drive so much? (And yeah, duh, also robot drivers, once they're reliable and don't kill people!)
Instead of making better prosthetics and wheelchairs, why not human limb and organ regeneration? (And yeah, better prosthetics and wheelchairs too.)
Instead of an AI arms race between blocs, why not ask it how we can all get along and take care of each other in cooperation and harmony?
(This one has not the "why not both?" energy, eh?)
In sum, once you get the hang of it, every single dumb or terrifying thing has this alternate "what if good idea instead" dual to it.
It just takes a little intelligence to find it, and now the machines are intelligent enough to look for mutually beneficial solutions if only we would ask them to!
(And yeah, ethics... We need to rebuild ML systems on ethical lines and use those instead of these Ouija board/slot machine fucking things.)
But again, as I'm always ALWAYS yammering on about: we already have all the solutions we need, we just have to notice that and apply them.
