Thoughts about SETI and SETI@home
ET exist, of course. Intelligent? Maybe. Maybe that definition is irrelevant.
When humans recognize they? Soon...
If they are a lot more advanced than us, they will not contact us, or maybe we don't recognize his presence. If they are a little more advanced, the contact will change and destroy actual living system in a way or another. If they are less advanced, poor guys.
Of course we may try to send a request call. The type of information, I'm not the better mind to think that. You are doing it well. But that Pioneer plaque was a silly thing.
I run S@H for the joy of collaborating in a global effort to explore new worlds. If we can contact, there is a lot of posibilities of a good change.
Humans have reach a limit in development and need to expand out the Earth. Unfortunately the social and technological development are not the better for that. But if we don't grow we are lost. The only things that can alter actual situation is a contact with other worlds or the discovery of great benefits outside the Earth. This second alternative may occur in 50-70 years. We have not so time. Or at least you.
