1. Seeing as we have never made a computer able to be conscious, or hear/see/smell/touch as good as us, or reach the same power-efficiency I'd say there is an absolutely an enormous amount we still don't know.
2. Life started off as the smallest thing possible (atom/quark/something smaller) and grew upward into cells, then multi cellular and so on. All the while being present in the natural world and getting feedback from the best test environment there is. In comparison our computers started off as bricks, and over time we've slowly shrunk them down to what we consider small. But we still have nothing on evolution.
3. The unknown can often appear like magic, but as the rise of neural networks in computing has shown, we are ever so slowly unraveling the secrets of the brain. Image recognition has come a long way compared to 10 years ago, and the techniques that are working in machine learning now are changing the way neuro-scientists interpret the structure of the brain.
