I guess it depends on what one considers to be programming. For certain DSLs (audio, control systems, UIs), it seems to be doing OK. For general-purpose work, I think they will always be less desirable than text. Even after thousands of years, words are still our most powerful tool for recording and sharing new ideas.

For professional work, when you already have the concepts down, it just gets in the way.
