This is the difference between the scientific approach and the engineering approach. Engineers just need results. If humans had to mathematically model gravity first, there would be no pyramids. Plus, look up how many psychiatric medications are demonstrated to be very effective, but the action mechanisms are poorly understood. The flip side is Newton doing alchemy or Tesla claiming to have built an earthquake machine. Sometimes technology far predates science and other times you need a scientific revolution to develop new technology. In this case, I have serious doubts that we can develop "intelligent" machines without understanding the scientific and even philosophical underpinnings of human intelligence. But sometimes enough messing around yields results. I guess we'll see.
