When I was in high school I asked myself at one point: "Why do I care if my high school's team wins the football game? I don't know anybody on the team, they have nothing to do with me... why am I here and applaud? It does not make any sense." But the point is, it does make sense: It's a way of building up irrational attitudes of submission to authority and group cohesion behind leadership elements. In fact it's training in irrational jingoism. That's also a feature of competitive sports.

Technology can also be used so that private individuals will have access to the way centralized decisions are being made.

The tendencies are considerably weaker in the natural sciences, which, for the past several centuries, have survived and flourished through such constant challenge, and therefore, at best, seek to encourage it. Serving the status quo in political and socioeconomic realms is a different matter.

Democracy is always harmful to elite interests. Almost by definition.

In the literal sense, there has been no relevant evolution since the trek from Africa. But there has been substantial progress towards higher standards of rights, justice and freedom - along with all too many illustrations of how remote is the goal of a decent society.

I don't think you would have any trouble at all in deciding that you are thinking of some event and then visualizing it happening with its consequences, and constructing a rational analysis of it without being able to verbalize it adequately in anything like its full complexity.

If anybody thinks they should listen to me because I'm a professor at MIT, that's nonsense. You should decide whether something makes sense by its content, not by the letters after the name of the person who says it.
