Did you read the link I provided? Intelligent silicon life has good reason to believe that carbon life is quite a bit more likely than their form of life. Just as we have good reason to think intelligent silicon life is very unlikely.
My point is precisely that this isn't just random chauvinism, which is rather than being some sort of way-cool open-minded "whoa" opinion is really rather insulting to the huge number of scientists who have considered this matter very carefully. There are a looooooooot of good reasons to think carbon is the only possible substrate for life in this universe, and a lot (still italicized, but with fewer "o"s) of good reasons to think water is the most likely choice.
