Yo - I did the Airbnb project linked ^^^ which I believe was the first of this wave of deep learning-powered sketch->UI projects (though standing on the shoulders of decades of R&D projects)
Our take was that we really do design on paper or whiteboard first & foremost, which is why our project emphasized the webcam + sharpie thing rather than drawing in-browser etc.
Here's a related thing I wrote about the need for design tools to design the real thing, rather than facsimiles of the thing: https://jon.gold/2017/08/dragging-rectangles/ - so so so much process waste is because developers have to re-implement static pictures of designs.
In our case, we didn't get buy-in to keep developing the project, but I'm kinda jazzed that so many people are running with the idea
