In the real world we rely on humans for lots of stuff, and humans aren't actually deterministic either. Sure, if you train someone to perform a task they'll probably do a good job, or they might suddenly come into work distracted and cause a problem. Diagnosing problems with people is often similarly hard, and we've had all of civilization to work on it.

This hasn't caused the sky to fall, yet. So, perhaps we'll just learn to make AI behave properly under most circumstances, and deal with failures and glitches as we always have with people.
