> One of the many reasons I became a programmer was that the sky was the limit. Still is. Want to learn something new? Learn it. Want to build something cool? Build it. The only real limitations are your belief that you can do it and your willingness to perservere until you do.

That's not what he's saying.

He's divided the world into two peoples: those with the capacity to program and those who cannot regardless of effort.

These groups are often confused because people can program, but only may do so badly. Yet even being a poor programmer puts you in group A, and effort will make you a better programmer.

On the other hand, there are those who cannot program: cannot write a loop, cannot use variables, cannot create a working algorithm even with copy and paste.

The may perhaps be able to do simple math, but when it comes to composing equations or functions together into an interdependent process...they are simply unable.

They may try if they're so inclined to learn programming, but they'd die of old age before they can even begin to reach a standard that we'd call mediocre.

That is what he is say. Agree or disagree with it, but misunderstanding it skews the discussion.
