The goal was to explore the idea of contextualizing our tools for each development. It is built in Smalltalk (and Rust underneath) because Smalltalk already has the possibility of a live environment that can be changed from within. This allowed us to explore the space at much lower cost. Glamorous Toolkit is the result of that.
Thank you for the kind clarification. Indeed, it describes my intent quite well. Thank you for taking the time to describe how it is perceived from your point of view. I hope this is useful for the initial recipient as well.
We chose Smalltalk because we could not have discovered the space (what we now call Moldable Development) within the constraints we had.
p.s. I learnt in the meantime that it's possible to downvote somehow (I still do not know how). But in this case, I actually upvoted you.
