Which does not make it unpredictable, if specifically 'non-deterministic' was meant. If something like 'halting' was, then sorry, but all languages are in the same position [was it about a language?] If that was about non-functional constraints (like real-time issues), then, well, RA is not in a beacon position here.

DBs are stateless, I presume...

I wouldn't expect such statements from people claiming themselves champions of theoretical formalism.
