I don't think anyone looks a biological systems and thinks they are well described by P(reproduction|environment). ChatGPT, on the other hand, is P(text|internet) more or less by definition (it's more than that, but not much more).

The fact that we observe what looks like emergent structures such as "understanding", "knowledge" or "reasoning" is fantastic, but it is not in any way incompatible with a P(text|internet) model simply "mimicking" humans.

I agree that exploring the inner workings of these emergent features is interesting in it's own right, but all that glitters is not gold.
