From what I understand after watching true video, I think this abstraction could work for extremely simple implementation details, but once the implementation gets even slightly complex, the scale of complexity of coding it with this system balloons.
That's the exact problem I encountered when I worked on a similar product for microcontrollers.
Having to use a mouse to interact with your programming ide graphically doesn't scale. It does make for a decent tool for hobby projects or prototyping though.
