I thought this was going to be vaporware, but man, I'm impressed. If it can really do half of what the introduction video shows, I'm can't wait to play with it!
One thing I think is particularly interesting is that the onboarding process lets you use natural language to figure out what WolframCode to write. Slick!
Have you used Mathematica before? Other than deployment capabilities everything in this demo was available in Mathematica for more than 4 years already.
This Wolfram Language is nothing else but smart PR.
