This seems to follow natural evolution, everything coming and going in waves, each time reaching a new evolution and better version of that older wave. Before personal computers, terminals were the thing, just connecting to a mainframe and executing programs there, then we reached the state of standalone computers being offline for a while mostly, then the Internet boomed really fast and computing went more to server/client model, and now we are going towards back loading code from a server, but having more intelligence in the client and executing more offline.

It's interesting to notice these things repeating themselves, I bet at some point maybe the OS and the computer merge more and we will have again more systems like we did when the Internet became to rise.
