...Just no. Animals are complex organic beings. Of course, we don't understand them. Machines, though? We built machines from the literal Earth. Their level of complexity is incomparable to that of anything made by nature.

Now, take a sufficiently advanced neural network that's essentially a black box that no human can possibly understand entirely and put it inside of that machine? Then you're absolutely right. We'll get there soon, I'm sure. For now, however, a physical robotic body is just a machine, no different than a car.
