This is a UI prototyping tool, and a potentially good one at that. It does not develop what a HN audience would call production ready applications. That being said, "Production Ready" as used by this author is very different than what "production ready" as used by the HN audience means, a look at the end of the linked video where he claims a checklist with drag and drop support and cookie-derived sessions next to is "Production Ready" should sufficiently demonstrate that.
And that's okay! It doesn't need to have replaced the entire Web Developer career field, it can just be a cool UI prototyping tool. But I might suggest to the author to reduce the scope of their claims a touch, as it would engender more positive discussion.
And what about when you need to glue an external library into a page, or pivot a feature.
I've seen design generating frontend as a promised holy grail, and it's still not there. The further away your design is from the person who actually builds the product, the longer and slower the turn around time is for the inevitable pivot or adjustment.
It's all 'perfect world' scenarios.
Creating a CMS? Sure. Web app that connects to x,y,z services and crunches a,b,c datasets? Not a chance.
