As much as I admire Processing for making it easy to draw pixels on the screen, something that seems to get more difficult every year, I do find it very difficult to use as a teaching tool. Going from Hello World to something more intricate is a bumpy ride with very few affordances, the feed through from drawing a rect to interfacing with I/O is, while obviously a difficult problem, non-existent. "Creative coding" also requires both a high degree of mathematical and artistic capability in order to be something other than a soup of primary color on the screen, something beginning programmer (esp. "non-technical" ones) tend to struggle with.
That said, I still really admire what they did and how extremely influential it has been. Just a small thing like how the the Processing IDE was forked to create the Arduino IDE attests to how Processing continues to reverberate throughout history.
Then there is also the famous Bret Victor article: http://worrydream.com/LearnableProgramming/
