Like, you've still got to edit the page to add links, images, colours, etc. In fact, that seems like the most complicated part.
It's a fun gimmick and a nice selling point. But someone will be able to use this idea for Wordpress/Wix/Squarespace plugin. Would be surprised if they didn't produce their own feature to do the same thing eventually.
It'd be way cooler if you could draw links on the page and it would figure that out. Or draw a box with some links in it and generate a header. Draw a box for a place holder image and generate that. The next iteration would obviously be using paper to design the actual site and then using CV to generate the markup/styling.
