Do they have models that try to downplay what happened on Tiananmen Square? That would be a sneaky way to shape our future in some way (and no whataboutism, we do it too).
Additionally it has been shown that making models forget things lobotomizes them, so no SOTA model can ever do that and be SOTA. They might be post-trained into pretending not to know, but the technology fundamentally cannot resist jailbreaking.
Do you have examples of knowledge that has actually become at risk as a result of this one AI model being added to the pile??
