Must be nice on the holodeck.

We understand the material conditions and how that drives not only ideas, but change as a whole. For example by carefully looking at the material world around me, I can safely confirm that Xi and Biden are two different people.

Bit of a late reply, but why is it so hard for you to imagine any leader caring about their people? (This sounded more accusatory than I meant, that's not my goal, it's more of a "why is it so hard to imagine a caring leader?" not a personal attack.)

Most of us in the west have never actually had a leader who wants to help anyone other than the stockholders of big companies. So the concept of leadership that actually cares about people is entirely alien to us.

To look at it another way: Do you consider yourself a good person? And if you were in a leadership position somewhere, would you try to do the best to help out the people under you? Good people do exist in the world. Not necessarily saying Xi is one of them, just that it is possible for a leader to care about people. Power doesn't corrupt, corrupt people are attracted to power. But they aren't always the ones who get it.
