The author is not unwilling to explain, he has lots of experience trying to explain and knows how hard it can be.

The best single sentence description, IMHO, is that GT (Glamorous Toolkit) is the current manifestation, implementation, proof of concept of the idea that making systems explainable through mouldable development is very powerful.

Furthermore it is a very nice tool in its own right (again IMHO).

Saying 'GT is x' where x is any of the subjects in the text is problematic. Most people will cling to one perspective, the one they are most familiar with or like the most, and mostly forget the other ones.

There is lots of stuff to read or watch:

- https://blog.feenk.com/ - https://book.gtoolkit.com

(BTW, everything you see in the above two web sites is actually written inside GT, notebook style with active content).

But reading about it is no substitute to trying it out and experiencing it yourself, though there is a learning curve for sure.

I've been reading much of this over the past day or so since I made the comment. I don't want to sound overly negative, but the author seems to think repetition of the phrase "moldable development" will imbue it with meaning, while my closest approach here is "notebook-style smalltalk ide."

Even when talking about "supporting" other languages, it's in terms of forcing everything into a smalltalk interface and then using that object model to introspect. None of the blog posts I've seen have convinced me that this isn't just Jupyter or Mathematica with a smalltalk kernel, and that's why I said what I did about the author's unwillingness to use common terms to describe the software. "Moldable development" doesn't mean anything.
