On top of "garbage in, garbage out" I don't see how AI was destroyed. It functioned as intended; learned from Twitter and responded as intelligently as it could with the provided garbage. If it spewed Politically Correct garbage, would it have been a success?
If "politically correct" means reasonable and respectful then it's not easy to see how that can be described as garbage. Given access to enough Twitter accounts and enough time the chances are good that eventually an ai bot might find tweets it might actually learn something from.
Certainly not on Twitter, where the moderators are so supportive of left-wing activists repeatedly telling people they disagree with to kill themselves that they ban the targets for talking about it and force them to delete their tweets complaining about it in order to be reinstated. Indeed, it probably wouldn't be politically viable for Twitter to do anything else in the current climate.
That might be true if an AI's needs were comparable to a human's. But the AI's we aim to develop wouldn't really face an existential crises when they go without food or sex.
We can engineer an AI's needs. You might as well say it should be a crime to train puppies to do tricks.
This is relative. What is garbage for us, is a goldmine for AI. We, people, think 1+1=2, we take it for granted, like everything else in this world. For AI, it's a different game, at a different level. IMO, let him tweet, apologize, but let it do it's thing and let's watch how it is developing. Also, so many butthurts over what he tweeted. This world IS garbage.
