Difficult to compare, not only neurons are vastly more complex, but the neural networks change and adapt. That's like if GPUs were not only programmed by software, but the hardware could also be changed based on the training data (like more sophisticated FPGAs). Our DNA also stores a lot of information, but it is not that much. Our dogs can learn about things such as vehicles that they have not been exposed to nearly enough, evolution wide. And so do crows, using cars to crack nuts and then waiting for red lights. And that's completely unsupervised. We have a long way to go.

You say "unsupervised" but crows are learning with feedback from the physical world. Young crows certainly learn: hitting objects is painful. Avoiding objects avoids the pain. From there, learning that red lights correlates with the large, fast, dangerous object stopping, is just a matter of observation.
