Well sure, if you compare a master to a novice, there is almost always a great difference. But between masters of carpentry, there is usually not so much difference. But here with the 10x trope it is supposed to be different and I would say indeed, but it is not as common as many would like to think.
Perhaps there aren’t that many non-master carpenters (I don’t think that’s true, there’s plenty of professional incompetents), but I am 100% sure that not all professional developers are “masters”.
