People hate change, and with good reason. Change makes us stupider, relatively speaking. Our knowledge -as a percentage of all the things that can be known- goes down a tick every time something changes. And frankly, if we're talking about a percentage of the total knowledge in the universe, most of us aren't that many basis points superior to our furniture to begin with. I hate to wake up in the morning only to find that the intellectual gap between me and my credenza has narrowed. That's no way to start the day.
