Science fiction is never about the future, in the same way history is rarely about the past: they're both parable formats for examining or commenting on the present.
Television is a constant stream of fact, opinions, lies, moral dilemmas, plots: an infinitely complex and sophisticated torrent of information. How could it not make you cleverer? The only people who ever thought television rotted the brain and made kids dumb were those with a vested interest in other ways of learning, or those who were intellectually insecure, usually about books.
If the world were to end tomorrow and we could choose to save only one thing as the explanation and memorial to who we were, then we couldn't do better than the Natural History Museum, although it wouldn't contain a single human. The systematic Linnean order, the vast inquisitiveness and range of collated knowledge and beauty would tell all that is the best of us.
