I think the main problem is the reverse Dunning Kruger effect. It can be very hard to tell what's not obvious to another person when the entire thing is self-explanatory to you. The two most intelligent people I know write code that works incredibly well, but you can tell it was coded out in one shot based on an idea they had. Makes it difficult to read, but to them it "just makes sense". A really good friend of mine is like this. When I read over his code, it's highly compact, and makes use of language features that are pretty obscure. The stuff he builds out addresses problem I would never have thought of. But the catch is I can't follow, or understand half his code. Sometimes though, there's an advantage here. Someone like that can get all the ideas out "on paper" (so to speak), then pass it off to someone who can make it legible for everyone else. There's a lot of value in someone like this, but you need to pair them up with the software equivalent of an editor. You'd be surprised, some people enjoy doing that!
