The Turing test isn't about the " intelligence" of certain responses but of the overall discussion, and a discussion that can go in any direction at all, at the questioners discretion.Especially GPT3, which produces intelligent responses that easily pass the Turing test.
Have a search on Google about how to fool GPT3.
Yes, it communicates in a very natural way, which is what it was designed for, but it is not capable, yet, of passing a Turing test. It won't, for example, say that it doesn't know an answer, but instead tries to come up with an answer, which gives the game away.
The video of the conversation was indeed impressive, but it was also limited in scope, the questioner not veering off on tangents, not trying to trick GPT3.
