Yet we have no understanding, only prediction. We can describe a great many things in detail, how they interact - and we can claim to understand things, yet if you recursively ask “why?” everybody, and I mean everybody, will reach a point where they say “I don’t know” or “god”. An incomplete understanding is no understanding at all, and I would argue that we can only predict, and we can certainly emulate reality, otherwise we would not be able to function within it. A toddler can emulate reality, anticipate causality - and they certainly can’t be said to be in possession of a robust grand unified theory.
