As for "true intelligence" - I honestly don't think that there is such a thing. We humans have brains that are wired based on our ancestors evolving for billions of years "in every possible environment", and then with that in place, each individual human still needs quite a few years of statistical learning (and guided learning) to be able to function independently.

Obviously I'm not claiming that SIMA 2 is as intelligent as a human, or even that it's on the way there, but based on recent progress, I would be very surprised if we don't see humanoid robots using a approaches inspired by this navigate our streets in a decade or so.
