How is this different from “drawing is better than writing a book”?

Some people write, others draw. Each method has its own strength and problem spaces.

Encoding a complex issue sometimes is just shitty with a visual metaphor. Other times writing code is a really bad idea. If you want to express “flow” or “connections”, filter or stream systems like modular synths, that’s when the visual metaphor shines.

You use whatever metaphor works best at the moment. One cannot replace the other.

The “problem” is that people want to push all of “programming” into the visual metaphor. That’s like pushing all of programming into only functional, only declarative, only imperative or only OOP (or whatever), but worse. That’s not going to work, but I guess people can try.
