There are also a lot of non-deterministinc choices one can make. Things like carry forward losses or gains, that no algorithm could know. They depend on your personal plans for the future. You can make specific filing choices that have massive consequences on your future. There are choices like 83(b) elections that can save you tens of millions of dollars a decade in the future, contingent on the events after you file.

Those are deterministic choices...

Deterministic means that the results are not random, not that they are known at the time of the initial choice.

This seems like splitting hairs. The outcome are not known or calcuable.

I suppose a dice roll or the motions of a butterfly are deterministic as well, if you have a full model capable of fully modeling the world.
