It's interesting that this anecdote is from Apple, as Steve Jobs was a famous proponent of the 10x or 20x programmer and hiring only the best available. In contrast at Microsoft Charles Simonyi took completely the opposite approach, with a highly stratified organizational structure dependent on hiring large numbers of drone programmers[1] and reducing programming tasks down to easily implementable essentially rote modules.
I don't think it's a matter of one model or the other 'winning' though as the Simonyi strategy certainly seemed to work for MS.
