Ask HN: Why isn’t visual programming a bigger thing?
This comes up in comp sci every so often since the 80s when it first gained traction. I think the short answer is that boxes and wires actually become harder to manage as the software increases in complexity. The "visual is simpler" idea only seems to hold up if the product itself is simple (there are exceptions.)To my mind, this is analogous to textual writing itself  vs drawing where text is an excellent way to represent dense, concise information.
