I think some of the frustration may be due to Thrun and Norvig style of asking questions he has not yet fully explained and requiring mental leaps.

This seems uncomfortable at first and getting things wrong is hard to bear in the short term.

On the flipside a better and more long lasting understanding is gained from working things out rather than just learning facts.

If they had waited till it was perfect perhaps it would never have happened, teach early, teach often.
