Can seasoned Blender users can visualize and compose Geometry Node graphs in their minds? It seems to me that it would be pretty hard, simply because of their clunky design. In my opinion, the only thing missing from Blender's amazing Geo Node system is icons, i.e. something compact and symbolic that one can store in their mental space as they would a word when composing a sentence.

I do also feel like a top down flow is more conductive to "process-oriented" or procedural design. I've done my fair share of procedural visual scripting with nodal systems such as UE4's Blueprints, PopcornFX or Blender's Geometry Nodes and none of them feel as "natural" as Houdini's.

It almost feels as though vertical lines occupy less space in my mind than horizontal lines do. Perhaps it's because our brains are hardwire to deal with lots of top down structured environments (plants, tree-trunks, other Sapiens).
