Like everyone, all of it. Doesn't bode well for this product idea.

How long did we try to get UML to work? There's a reason that visual representations haven't taken off, it's not like they haven't been tried before. And don't get me wrong - there are absolutely use cases for these types of tools, but at the end of the day, I think there are just too many challenges in visual representation for this to to work for "any application" (as Luna claims).

UML solved a non problem, tied to a bureacratic software design method. And it wasn't even executable.

And this feels like solving a non-problem as well, IMHO.

Yeah - this is a hard problem and the chances are small.

Nevertheless if you had 20+ years of experience in programming textual languages than it is no surprise that you understand them better than visual languages. That part of your argument does not seem valid.
