I can easily see a world where history repeats itself here. VMs get thinner, hypervisors get fatter to make up the difference, all the other layers of abstraction get squished out of the system, and what we're left with is just another process model. It's a model built on different assumptions than the one we're used to, with stronger guarantees about isolation than we might be comfortable with at first, but one that has an appeal even for desktop computing. Later, once everyone has a hypervisor in their pocket, we tell our children about how cloud infrastructures used to be so expensive that only big corporations could maintain them, and they came in server racks the size of refrigerators.
