I see no fun in using a WYSIWYG instead of a text editor & code. I also foresee trouble when a developer will have to deal with the produced code (Or rewrite everything from scratch).
One of the great things about WYSIWYG is it brings you closer to what you're making. Bret Victor nails why this is important in his talk "Inventing on Principle" - these tools help beginners shape their idea into something usable. And obviously these things can't scale like Airbnb, but they can scale enough to get traction and convince a developer to join your team. As a potential co-founder, would you feel better about joining a non-technical founder 1) with an idea on a napkin or 2) some traction and a code-free prototype.
