Artificial intelligence is different from machinery, which is made to replace human beings to do repetitive and monotonous physical labor, aiming at liberating hands, while artificial intelligence is made to replace human beings to do complex mental labor, aiming at liberating brain.
After understanding this, we can't help but wonder, when both the brain and hands are liberated, what is the meaning of human existence? Endless pleasure?
Whether it's self-driving or smart speakers, they haven't shown this posture yet, what they do instead of us is still physical labor after all, only these physical labor is more complicated,the ultimate goal is not to free the brain, but to make people's lives more convenient.
Artificial Intelligence's biggest "downside" is that it will lead to more and more unemployed non-brain workers, because almost all simple labor can be replaced by machines, and the reason why the current one is not yet available is just a cost issue. For example, the Haidilao restaurant, there has been a robot waiter, although the gimmick is greater than the practicality, but this seed is already visible.
Secondly, after life became more comfortable and convenient with the addition of artificial intelligence, humans became lazier and lazier. In fact, this is not a disadvantage at all in my opinion. It is the nature of human beings to be lazy, and it is precisely because of this nature that people will continue to develop technology so that they can live a more comfortable life.
The current AI doesn't have too many downsides to worry about, so instead of worrying about that, we should worry more about whether these immature AIs will pose a threat to our personal and information security. The scene in the sci-fi movie appeared in the artificial intelligence to rule over human beings at least a short period of time is still impossible, today's artificial intelligence is still essentially a kind of mechanical.
