Who's "We", Yuval?

Reminds me of an old Lone Ranger joke.

Yuval Noah Harari, historian, futurist, and World Economic Forum (WEF) adviser, said, “We just don’t need the vast majority of the population” in the early 21st century given modern technologies’ rendering human labor economically and militarily “redundant.”...

The punchline of that old joke was "Who's We?" 

We're sure that Yuval's answer differs from ours.  But we have weapons.
