I agree. Trying to second guess the computer revolution will make a fool out of you. 20 years ago nobody would have guessed the future of cell phones from simple calling devices to full blown computers. The same with the internet of things. Who would have guessed a refrigerator would have a smart TV embedded in it. There are still lots of legs in this computer run. And one thing to remember is that they all run on software. Programming is a very valuable skill. Shoot , there is plenty of work on the security side to stop hackers. One needs to understand programming in order to stop hackers.
