What I can't wrap my head around is the difference between "computation" and consciousness when it comes to intelligence. If intelligence is just the ability to receive the right signals and then output the right signals to reach a certain goal, then the more inputs and outputs you have, the more intelligent you are. But then this is not how we usually think of intelligence. Intelligence is like the ability of a limited organism with limited inputs and outputs to make the most of a situation. We can already design a super intelligent system that will process inputs exactly right and output exactly right, but you need the central control and the limited body that will enable some kind of will and prioritization, and I haven't even gotten to conscious experience yet.

Rather than being complex computation, intelligence is about flexibility, but it may be that due to the complex nature of our biology, all that flexibility is just a lot of inputs and outputs, in which case we're back to square one and the limitations of the body etc. In some odd way, intelligence is quite disappointing
