While the copy sounds like complete fluff-n-puff, I honestly believe almost all of it is right, both about what's coming for the future of coding and the role that visual "lego" programming will play in it.
There's just one really major thing the author got wrong: the reason visual programming hasn't (yet) seen broader adoption. The reason is that each visual programming tool consists of one language married to one editor. Who wants to re-learn a whole new editor each time they need to work in a different language?
