Even an average human engineer is at least six levels higher than the blind idiot god, natural selection, that managed to cough up the Artificial Intelligence called humans, by retaining its lucky successes and compounding them.

You say "at least six levels higher". This strikes me as rather precise. Does that mean you could articulate what these levels of intelligence are (at least roughly)? If so, I'd be interested in hearing it. And can you (at least roughly) articulate levels of intelligence above the average engineer? I'd be interested in hearing that as well.
