Nope. The biggest surprise about life beyond Earth is going to be how incredibly similar it is to life on Earth: Down to the fact that intelligence like ours will be found in warm blooded, bare skinned bipedal hominids who look and sound just like us. Why? because life has evolved out of necessity into every form possible here on our planet. Silicon has huge disadvantages compared to carbon and carbon is vastly more prevalent. By the way if you want a prediction: human-like intelligence is formed where planets with a molten core (and hence a magnetosphere) cause plate tectonics and the consequential glacial eras that force life to evolve warm blooded strategies. Furthermore, all species with human-like intelligence will be relatively short lived because they will be burning the fossil fuel, also a consequence of plate tectonics, present in their planet's mantles. I'm fairly certain this is the ecological role of species like ours actually - carbon liberation in the face of planetary glacial annihilation.
