ASK HN: How do they see world after 20 years?

I always imagine how world will look in future. But whenever I start following any hypothesis, I found that everything which I am thinking is so limited what already exist may be its more of combination of things which are there and making them more better. Suppose I see HN in future to be replaces something where when I post comment in a way I am virtually real time speaking to other guy regardless of where I am using some tiny device in my eyes. Many People this is possible using glass, I am saying what we apeak to them at that time they can be busy or sleeping as different time Zone but AI become so much advance and personalized to human man that it replicates most of a personal human and talk to other human. It will be fun to see two Personalized AI talking to each other and making business deal. Yeah, See Everything which I wrote already exist in some raw form. Will be very good to know how other see world in future.
