This really comes down to what we want to do as species. If we want to end up like the fat people cruising on hover pads looking at a tablet all day than this "sliding" future is almost sure to happen. (btw, people are lazy). The major problem is that future work will involve a lot of looking and manipulating things on the screen (in the developed world this is already happening). This makes your body useless, it makes it weak and prone to illness. We were not designed or we didn't evolve (choose your pick) to sit all day in front of screens.
