I think of myself as a visitor from another dimension, very much like this one, but with a higher level of technology. In our "realm", we have learned how to manipulate matter in such a way as to allow a person to litteraly enter a computer program. In fact, I like to think of this reality as the program I created for the sole purpose of figuring out our own problems. I don't mean that I am God or anything, just that all of this is an illusion that I created.
Thoughts about SETI and SETI@home
Do I think e.t. life exists? Of course. Otherwise, I wouldn't be participating in this grand experiment, now would I? I don't think there are any dangers. If they wanted to harm us in any way, shape, or form, they would have already. I also believe with increased intelligience comes decreased agression. I don't think any being can be totally non-violent, but I do think they can control those tendencies. The benefits of discovering a intelligient form of life on another planet include sharing of technology and an ally, should we ever need one, among other things.
