You're absolutely right that every one of these problems tends to go away with time; that was the one disclaimer I forgot. The more dev work someone has done, especially on collaborative projects, the less likely they are to have these problems.

You're also absolutely right that CS training isn't a panacea. Actually I tend to suggest math or electrical engineering training to people looking to get into the field. CS programs tend to overcorrect in some areas. For example, new CS grads often want to overuse regular expressions.
