Correction: (a) we can observe the effects of human-level intelligence but we don't actually know what human intelligence is because intelligence is best described as a side-effect of consciousness (aka the experience of qualia) and science has yet to provide a convincing explanation of what that is exactly.

> … what human intelligence is because intelligence is best described as a side-effect of consciousness …

Is "human intelligence" and "intelligence" equal?

And: How to become conscious before being intelligent?

Or: If intelligence is a side-effect, how often this side-effect can't be observed?

Xor: What if an intelligent being denies being conscious?

[IshKebab]

I didn't say in (a) that we know what human intelligence is exactly. I said that we know it is possible. It exists.
