I liked Segan not because of his Science, but by making people around him understand that even in the mundanity of life there are moments of pure wonder. Tyson… I like Cosmos, I like how he waxes philosophical. However like others in this thread it seems that here lately he has devolved into smug slapping down people who dare find anything wondrous about anything.
In other words current tyson is acting like the anti to his past self which advocated embracing the wonder of all things science can show us.
