Developer UI Testing

This paragraph:

“But for the actual developers, this compensation mechanism is far more effective. The actual developers (a) have enormous experience with the hubristic UI, (b) have enormous patience with its flaws, and (c) most important, know how it actually works. So their internal model can be, and typically is, orders of magnitude better than that of any naive user. So the product actually seems to work for them, and does. Unfortunately, it’s hard to make money by selling a product to yourself.”

From the following article, references developers testing intelligent UI’s, but in reality the same antic-dote could be applied to all developer testing.
