Regarding the analogy you use where humans etc not being aligned with each other implying that human-machine alignment is equally hard: Humans are in competition with other humans. Nation-states are in competition with other nation-states. However AI algorithms are created by humans as a tool (at least, for now that seems to be the intention). Not to say this is an argument to think alignment is possible but I do think this is a flawed analogy.
