If you can't write the software that runs the flowcode with flowcode it kind of makes it simply a different notation and not a revolutionary paradigm shift?
You theoretically could. Not sure it's the right tool for the right job.
We believe that many programming tasks are better done with textual coding.
Interpreting Flyde (the visual programming language behind Flowcode) flows and running them (see https://github.com/flydelabs/flyde/blob/main/core/src/execut...) ) will not benefit from being visual. It's mostly synchronous, borderline fractal logic.
A great use case for visual programming would be a task that involves several LLM calls, third-party vendors, and some transformation logic on top.
