Next generation computers

Tweet

I am trying to imagine how new computers will be. After the invention of multitouch, we got the surface computer, with no keyboard or mouse or monitor, just a surface with the screen on it and u touch it, move object inside it, even rotate them and enlarge or rotate them. Let's have a little jump to the future.. will we have computers in our brains? or maybe we will have a human like robot that is actually a computer programmed and trained to do more than expected from him. Will little children find some computer games or they will find a robot to play with them. Will watching a movie be like having a dream? Will issuing command will be just thinking about it? Will we able to use computers to see someone, hear someone and smell someone? I think this is all will happen in near future. Or I was overdreaming a little?
