In a regular OS there would be a bunch of implicit things provided by the OS that the app can access, while in this OS those things are explicit in the context. But I don’t think that’s really that significant… you could, e.g., enumerate all the implicit things the OS provides, express them in a structure, and now you’ve got your explicit context. The “fomos” context is only as simple as it is because the OS provides a small number of simple things. Expand those to full OS capabilities and the context will get full OS complex. The odd thing about this “OS” is that a running app is just the start function called repeatedly in a loop. This makes one app call a single coherent slice of app execution. That’s kind of interesting, but makes this pretty limited. E.g., it looks like apps are entirely cooperative. It’s maybe more of a cooperative execution environment. Maybe it would be good for some embedded uses?
