A great read, I’ve seen similar visual coding tools such as ardublock (arduino based) and illumination software (created by Bryan Lunduke which was sadly discontinued).
I think a lot of the responses you have received have thrown the baby out with the bathwater and some have missed your points completely. Frameworks are always being advanced and each time they do it saves us all some time, and I see your post as basically taking these tools to the next level. Your music example made it very clear and you know how much people (and dinosaurs) misunderstand the use of computers as tools for music creation. I’m very interested to see where u take this in the future.
