I think these books are not really meant to be a PhD education but more of a tutorial introduction to the field. What O'Reilly is doing right now is really important. As Steve Yegge said, they are "trying to provoke a culture change."

Would-be brogrammers will find these books, read them, and graduate from cat-picture projects into more sophisticated applications that can solve real computer science problems. It matters less whether the readers of these books actually get a comprehensive understanding of the theoretical knowledge behind them, then it does that they enrich readers and spread the desire to learn and attain true understanding of the field.
