I find the entire article quite poorly thought out and I disagree with it more or less entirely.

One part in particular stood out as being perhaps the most offensive to reason:

"Professional talent does vary, but there is not a shred of evidence that the best professional developers are an order of magnitude more productive than median developers at any timescale, much less on a meaningful timescale such as that of a product release cycle."

I really don't understand how anybody with experience in our industry could say such a thing.

I would have thought it was fairly routine for "professional developers" (by which I assume he means those devs who work in companies) to meet large numbers of people who are completely incompetent.

So in my view there must be a huge amount of first-hand evidence to support the statement that some people are 10x better than others (or even the more stringent requirement that they're 10x better than the median).
