>> Organisms have had billions of years of training. You're referring to evolution but evolution is not optimising an objective function over a large set of data (labelled, too). Evolution proceeds by random mutation. And just because an ancestral form has encountered e.g. ice and knows what that is, doesn't mean that its evolutionary descendants retain the memory of ice and know what that is because of that memory. tl;dr evolution and machine learning are radically different processes and it doesn't make a lot of sense to say that organisms have "trained" for millions of years. They haven't! They've evolved for millions of years. >> What’s billions of years of sensory information that drove behavior and selection, if not training data? That's not how it works: organisms don't train on data. They adapt to environments. Very different things.
