> The OS clearly seems to be going in the direction of Smalltalk or a Lisp machine as an environment. What would it look like, or what would be the limitations of a merged OS/programming environment with something like a single SQLite DB as the filesystem? MUMPS, most 4GLs, RPG on the AS/400. I have not programmed in any of these but have heard a lot of bad things about them. Also I think it is a mistake to say the the OS is going in the direction of Lisp/Smalltalk. If anything, Linux containers/Docker is more like the IBM VM mainframe operating systems.
