I'll second this, with the caveat that I've not yet tried to build anything with Fable.

Every engineer can now produce things in the front end that doesn't look like complete and utter garbage, sure, but everyone is also producing the new-era of Twitter Bootstrap pages. It all has the same touched-by-AI look and it might as well be customer kryptonite from everything I've experienced at my workplace with customer surveys and collaboration. It has raised the floor substantially for internal tools and admin pages though.
