I read this more as: "stupid is an important step in the process of fostering smart". It's someone's unwillingness to look dumb that stalls them at the gate.

I think this is the impetus behind the whole 'crawl, walk, run' thing. If you're always hot to trot and pushing an image of "I know everything already and I don't need to ask basic questions", you're never going to build the foundations of understanding necessary to construct more complex understandings.
