I used to think so - once you have persistent primary memory, you can install operating systems and applications directly into primary memory, so there's no longer any point in having a distinction between "install" and "run/boot". However, iOS and Android have shown that it's possible to do away with this distinction even with a traditional OS running underneath. So I now tend to think that instead what will happen is more continual evolutionary changes at the OS level to work better in a "boot once" environment, rather than a revolution. |

When Linux boots, the in memory state changes quite a bit. Even the actual code gets modified during boot. The whole process takes well under a second. Linux does support an “execute in place”, but it’s barely a win, and I don’t think it works on x86.
A more interesting idea is to put your OS installation on a DAX (direct access) filesystem.
