Then you need at least to have some overlap between the "hackers" and "developers" areas. And there are hackers who aren't programmers. And there are developers who aren't programmers.

And are the programmers who are neither hackers nor developers?

Or perhaps you are only considering the world of programmers. It's really not clear.

I say all this as a mathematician who occasionally hacks, occasionally takes on the role of "developer," and while I believe that there is space for an article that makes the differences and commonalities clear, I don't think this is it. It feels like you have truth to convey, but this article doesn't do it.
