For most applications, having used a few 2D "programming languages", I disagree.

2D layouts are simply too hard to follow once things start getting complex. You spend a lot of time reorganizing stuff. If you find writing clean code hard, making clean graphs is hard squared. As for spreadsheets, they are good for manipulating data, but for logic that is a little bit complex, they are terrible.

The author claim it is better for parallelism, but even for the most parallel application: chip design, most people use text-based "1D" programming languages (HDL) when things get serious.

Also, do you remember UML? It used to be super trendy in the 90s. Now, I almost never see it used. Sometimes you get a class diagram, usually generated from code.

2D layouts can be nice on a very high level. Connect the boxes. Digital audio workshops tend to work like that, but behind the boxes, this is regular code.
