The one thing in it that Pd does not provide is the ability to click on the generated image in order to see which code is generating that part of the image.  That would be a nice feature to have.  But I can't see how you would generalize beyond drawing pictures.  Drawing with code is basically the easiest realm to solve that particular problem, IMHO. How would you click on the sound to see the code that is generating it?  How would you click on a mail program, a network service, file encryption?

Having a two-way connection between graphical representations of audio/music and the underlying code would be quite useful and conducive to empirical experimentation.

Yeah, i agree, I guess I'm responding to the speaker's tone.  Something about him rubs me the wrong way, it seems like he claims to invent all this stuff, then talks about Engelbart, Kay, Tesler as if they were people who invented all this stuff in isolation when in reality they all were working in large, collaborative labs.

He also seems to imply that the techniques he demos are easily applicable to everything.  That's unfortunately not really true.

I like the idea that software work should be guided by principles, that is what guides a lot of the contributions to Pd development, I think.  And he does a good job of explaining why rapid feedback loops are important.
