I have the same optimistic belief as you, but I wonder if the world really works like that. Meta employees (who are by definition smart enough to get the job) haven't all quit after reading the studies that show that Instagram usage results in teen depression and suicides.
Or perhaps that supports your point. The smart people with fluid morality are vacuumed up by the Metas of the world, leaving none that would build a nuke for a third world dictator.
