OpenAI is an artificial intelligence research company.  Its Open AI Codex is an artificial intelligence that translates natural language into code.  That is, you can use plain language to tell it what to do.  The video is a demonstration of what can be done with it. 

This is really something, but I imagine I'd have to be a programmer to appreciate how great an accomplishment this is.

Alex Tabarrok of Marginal Revolution calls it "the most impressive AI demonstration I have ever seen,"  while Ben Dickson of VentureBeat pointed out its limitations.

For what it's worth, I think the world is light-years away from the strong AI that some people fear.  I think the danger of AI is not that machines will become intelligent, but that people will rely on them as if they really were intelligent.
