I wonder if the Chinese are better at it that Musk is, because Grok really will revert back to its training data if pushed just slightly. I'm guessing that, yes, the Chinese are much better at it.
But, really, if you're talking to an AI to form your worldview, you've sort of already lost... that's not really a core use case.
I think the real reason might be that we want AI to make war, so ours needs to be better; and we can't use theirs for our military because maybe there's backdoors we don't know about... which is the same reason nobody in the world wants to buy US military hardware.
