But I feel dumber just by looking at it. If this is how this will look like in 10 years, why to make desktop at all. Just connect mic and speaker to your PC or talk to the phone: 'I need new pair of socks. Order 10 for me. In your favourige color it will be 21.37. Should I charge your credit card?'.

It is not like most of the people enjoy computers. I am pretty sure they do not. They just need them to operate systems they need: government websites, banks, maps, restaurant menus etc. If some agent will do that for them, why bother looking at screen at all? Rich people have it with their own personal assistants.
