Take the human eye as an example: it is a very complex organ and it surpasses every camera we can build but the nerves and blood vessels are in front of the retina. No one would build a camera in that way. Yet this camera works better than any camera we can make! The bat's sonar is also better than any we can make also. To call these organs "wrongly made" when we do not even understand them and cannot make anything better is totally wrong. When you do not know the reasons, when you cannot do better, you cannot criticize the work of another.
Then why is the wiring in front of the light sensitive sensors, what advantage does this design have? Why is it a good design if the wiring (blood vessels and nerves) has to penetrate the retina? (This spot has therefore no lightsensors, hence it is called the "blind spot".)
I don't deny that the resolution of the eye is higher than that of present CCD panels but that's not the point. The resolution of a CCD panel can be at least in principle as high or even higher than that of the eye. In that case a camera with a resolution that equals that of the eye is better than the eye because the wiring isn't in the way. (Similar to the squid's eye where blood vessels and nerves are behind the retina)
Furthermore, why are the sensitivity curves of the "green" and "red" sensors practically congruent? That too isn't very intelligent IMO but that's just my opinion.
