I have to work the night shift tonight, from midnight to 7am. This will undoubtedly give me way too much time to be alone with my thoughts.
And in the spirit of being alone with one's thoughts, here is a thought experiment I keep coming back to. What would the world be like if it were inhabited entirely by people who are exactly like you? Okay, maybe they don't all look quite like you, and there are still two genders, but personality-wise everyone is like you.
I think my world would be very peaceful. I also think everyone would starve after a while because people wouldn't really know how to go about getting food. Clothing would be optional. "Bad words" wouldn't be forbidden. There would probably be a lot of books around, but nobody would have the technical skill or insight to create a printing press, so any book written would likely be the only copy. Religion would be a lot more abstract and philosophical. Nobody would get Adam Sandler. Or Krzysztof Kieslowski movies. Or Metallica. Or Tom Delay. (Let's ignore the paradox). If technology got as far as TV, it would mostly play cartoons.
It would be an OK world, I think, but probably not one I would want to live in.
