waht will the world be in 20-50 years
AS for human's technology develops in everyday or even in every seconds. Noone will know what will hapeen in nest second.
AS for the future world, recenttly AlphyGO makes the upsurge of the talking of AI( artificial intelligence). AG is the AI which made by Google which gives her all the ways to play chess. However, in the compitition, AG makes decision which the maker didn't make that means she has its own imagination. For another example, once a scienist asked his AI what do you want do in the future. It said that I am going to learn and study in order to kill people,
So it's not hard to find that human will live with roborts in the future world and everyone will make a robort friend.
