Yeah no. I make software used on actual flight simulators and we literally need it to be deterministic, to the extent of needing the same help query to always return the exact same results for all users at all times.

Some business problems need that. That’s not the same as asserting most do and it’s certainly not the same all business problems.

Some things need to be deterministic. Many don’t.

Even your business will have many such problems that don’t need 100% all those properties - every task performed by a human for example. You as a developer are not all of these things 100%!

And your help query may need to be deterministic but does it need to be explainable? Many ml solutions aren’t really explainable, certainly not to 100% whatever that may mean, but can easily be deterministic.

If you were on a real flight and asked a human for help, they wouldn't give a deterministic answer. This doesn't seem like an actual requirement that is needed, but rather something that is post hoc rationalized because it was cheaper to make that way. While terms like consistency may come up when referring to having deterministic output as a requirement, the true reason could actually just be cost.

If you were on a real flight, asking a qualified human - like a trained pilot - would result in a very deterministic checklist.

Deterministic responses to emergencies is at least half of the training from the time we get a PPL.

Regulated industries (amongst many) need to be deterministic. Imagine your bank being non-deterministic.

>Imagine your bank being non-deterministic.

That's already the case. Payments are not deterministic. It can take multiple days for things to settle. The real world is messy.

When I make a payment I have no clue if the money is actually going to make it to a merchant or if some fraud system will block it.

		The bank can very much determine if the payment has been made or not (although not immediately, as you mentioned). As a rule, banks like to keep track of money.

		Yes it settles deterministically. With AI it claims to be settled and goes on, and it's up to you to figure it out how deterministic the whole transaction actually was.

		Is it the main issue? Payments suffer from race conditions, but the processes themselves are deterministic, auditable and may be rolled back. Not sure how many of these important attributes would remain with a neural network at the helm.

Even then it can be deterministic but not explainable. Tfidf is fairly explainable but about the limit imo for full explanations making sense such that you can fully reason about them and predict outcomes and issues accurately. Embeddings could give better, fully deterministic results but I wouldn’t say they’re 100% explainable.
