comparing this to IPython Notebook is a big stretch and an insult to MATLAB and IPython notebook. There's no way this would have ever come out of PARC, you're exaggerating Davis's work. Also, it's impossible to "look past the religious stuff" - it's part of, all of TempleOS.
To me this is just a crazy guy who's been tinkering with 80s technology while the rest of the world has moved on. I feel bad for him , but I just don't buy the "powerful idea with serious applications"
