> with no actual knowledge of cognition, psychology, biology

... but we also need to be careful with that assertion, because humans do not understand cognition, psychology, or biology very well.

Biology is the furthest developed, but it turns out to be like physics -- superficially and usefully modelable, but fundamental mysteries remain. We have no idea how complete our models are, but they work pretty well in our standard context.

If computer engineering is downstream from physics, and cognition is downstream from biology ... well, I just don't know how certain we can be about much of anything.
