Visual coding is huge among people who aren't technical. I first got into "programming" when I was 9, through lego robots, they had a visual control flow thingy, basically visual coding. I think that must have helped me understand programming and its implications much faster when I got into college.
Visual programming is not ergonomic enough to justify never writing code again. It will remain a paramount educational tool, and a great tool for designers and game developers. I believe people do use visual programming for Unreal projects (Unity, maybe?), textures, effects, etc.
I don't think it is aesthetic enough right now to get the masses into it. Visual programming will eventually be important in getting people to do more complex things on the web (think IFTTT).
