day 4 AI Artificial intelligence (AI) is intelligence exhibited by machines.--by Wiki. It's amazing that Tesla use many robots to assembly cars, most of the work in their factory is done by machine. so I do think artificial intelligence could be very helpful. But I'm not a crazy fan of AI, it has to have boundaries when applied in sociaty. No matter how intelligence itself, it's not a man, so people who invented the AI should take full responsible for it. It must be invented by good, kind,humanism purpose, such as help disabled people, doing the dangerouse task. Also, there are a lot of work and activities that people cannot be instead. Talk to your family, painting,singing,crafting,meditation, etc. In a short ,we have soul, we can feel, we must live like a human.If we only sitting at desk and dealing information all the time, then we just like a machine.
