I get the sense the end goal here isn't in productivity but more for education and creating environments that foster a programming mindset and/or nourish more emergent creativity from being able to code at a higher level (probably the most consistent theme in all of Bret Victor's forays).

In a sense, it's basically just a framework with a text editor that isn't based in an OS but instead a 2d surface that you interact with, using your hands and interacting in a more social medium than something like, say, git.
