I’m not sure what is next, but it’s coming, eventually.

Getting computers smaller and smaller gets impractical in terms of user interface. A possibility is neural implants. But the other direction we’re already facing is just smarter everything with microprocessors everywhere. Each device does not need to run Android to be useful (or annoying, because not everything needs to get smart and adding processing is also adding new and exciting failure modes). But each device still integrates a computer.
