The Turing Test (as some people believe it to be): if you can have a conversation with a computer and not tell if it’s a computer, then it must be intelligent.
AI companies: writes ML model that is specifically designed to convincingly play one side of a conversation, even though it has no ability to understand the things it talks about.
Also as Turing proposed it it’s meant to be infinitely repeatable. The test isn’t supposed to just be if a machine can convince one person with one conversation. That would be trivial. The real Turing test is the converse, it says that there should be no conversation one could have with the machine where it wouldn’t convince you it’s a human.
