I actually do agree with you while still finding Penrose persuasive. I don't know how earnestly he adheres to the "quantum perturbations in nanotubules" (if I've gotten the incantation right) for which he credits someone else as a good try at a solution, and I have the impression he holds it as an open question. I think the appeal (or interest, to me) from the phenomenology angle, is that we understand things by being in the world, having needs and desires, and some agency to obtain them. We understand a hammer because we can imagine a need to drive a spike, we can see that it can be held in our hands and be swung to drive the spike, that we have hands and a body, and that we occupy space. All of that made me wonder if simply executing a program is sufficient for emergence of intelligence. This raises the naive question of whether adding enough sensors and actuators to the program would be necessary, or have I merely added something unnecessary to the problem? Anyway, that's the kernel of doubt that I have that a computer program alone is sufficient for the emergence of an intelligence, that is, an agent with the capacity to understand.
