I'm the last to defend visual programming, it's mostly spaghetti nonsense and you'd be better of with an actual programming language for most complexity levels -- but I think there's a viable niche for stuff that satisfies both of the following:

(a) it's simple and it strings together off-the-shelf components;

(b) it has an intuitive, well-defined computational model

examples: defining compositions of matrix transformations for camera angles, defining data pipelines (read from this source, do these operations, write to that sink), very simple automation Apple Shortcuts-style (whenever I receive a message from this number, make a note on this file, etc.)

As soon as you venture into general-purpose territory, visual programming is just a disaster. Which is a problem because you have no way to convert your mini-idea into something usable, and you always find yourself wishing you had started with a normal script.

I tend to stay very far away, but it does have its moments admittedly.
