Elon Musk and Microsoft's boss saw something dangerous, it is a warning that we humans don't need to go too far with AI and too deep, like Building a human like a robot that's too smart or almost human, this will endanger the human race.
I don't know how true this story is, in China, an AI robot went berserk and killed a few laboratory workers, the government tried to bury the chaos and someone still manage to leak it but it does not take too long before the leaker was apprehended.
Everything that could benefit the human race has its disadvantages, there is no point in enhancing AI robots, even a PC can malfunction at any time, and there are viruses and malware that could make a PC behaves abnormally, same thing can happen to any smart technology.
That crazy Chinese AI robot? Sounds sci-fi. You know what? Strange things happen. The bot may have been upset or sick of humans. Who knows? We also need to build and use AI tech responsibly. Growth shouldn't blind us to AI's risks.
