Why we might be alone in the Universe

[vulcanlogician]

Besides an anthropocentric projection of our primitive social needs deriving from our particular precivilization social evolution,  what reason can you think of why a technological civilization might feel the need to communicate with those who could only understand very dumbed down communication by the standards of the technological civilization?

Curiosity might be a possible answer to that. A technological civilization would have had to learn about math and science somehow, and it's hard to see how unless they also had some innate curiosity. Don't forget that when we discovered that the solar system was heliocentric, this was useless information. It was curiosity to discover facts about the natural world that drove us to solve the mysteries of nature and only eventually did these discoveries pay dividends in technology.

It's also not absurd to assume that a civilization that has managed to get itself into outer space would be a social species. After all, getting off a planet is a group project, isn't it? And without a social element in the species's behavior facilitating cooperation for such projects, it would be hard to imagine how a technological civilization might arise. (I suppose it's possible, though.)

Just going by humans though, if we were to discover another planet inhabited by beings who used dumbed down communications (say at the level of the telegraph), we would be very intrigued and want to learn about them.
