Deep learning is hitting a wall?

I wonder sometimes how tiny brains work. Take butterflies: they can flit among flowers on a bush or in a small area on the ground; how do they know how to move around so they fly to a nearby flower, then stop and insert their proboscis into the nectar-bearing region? I guess there is no real learning going on--the behavior is probably innate--but still, it seems miraculous.

I agree, it is miraculous. the fact that dna is ultimately storing all the info for specifying neural circuits that robustly support such complex innate behaviors (often with very little post development tuning / learning) , that to me is mind-blowing. And butterfly behavior is one thing, but what about innate detection of predators in some visual systems? How do you encode a snake detector in dna?

I believe they call that Hebbian Learning in neuroscience.

Not really, hebbian learning is also learning from experience. Butterfly behavior is probably mostly hardwired.
