Edit: after downvotes I decided to read the whole thing afterall, but remain unswayed. This guy has an important opportunity and I sincerely dislike seeing it squandered.
Categorizing people into programmers and non-programmers neglects the people who need programming but not at an expert level. Some interns and students won't excel as programmers, but they still can bring programming into what they do instead, especially if efforts like Light Table succeed.
I suppose I shouldn't be surprised by this kind of pushback against reimagining programming — I've seen it as a response to some of Bret Victor's projects. Skepticism is great: Maybe the ideas behind Light Table are wrong or badly implemented. But we gain nothing from glib dismissals that seem to regard any attempt at improving or simplifying programming as beneath them.
There is progress to be made, and I'll be excited again when I see some.
I'm not always impressed by Light Table, but I appreciate the work the team has put into the problem and think they have good ideas.

I believe in the concept and potential; it's the execution that I'm finding fault with.
