How does it 'count almost everything as gambling'? They just said 'non-deterministic' output is gambling-like, that is not 'almost everything'. Most computation that you use on a day-to-day basis (depending on how much you use AI now I suppose) is in all ways deterministic. Using probabilistic algorithms is not new, but it your point is not clicking...
Almost everything is non deterministic to some degree. Huge amounts of machine learning, most things that have some timing element to them in distributed systems, anything that might fail, anything involving humans, actual running computation given that bitflips can happen. At what point does labelling everything that has some random element “gambling” become pointless? At best it’ll be entirely different to how others use the term.
Working with humans is decidedly not deterministic, though. And the discussion here is comparing AI coding agents and humans.
That starts to get into a very philosophical space talking about human action as deterministic or not. I think keeping to the fact that the artifacts (ie code) we are working off will have deterministic effects (unless we want it not to) is exactly the point. That is what lets chaotic human brains communicate with machines at all. Adding more chaos to the system doesn't strike me as obviously an improvement.
