I'm 45. I own my own technology company. I have been facinated with this stuff for most of my life and want to use my computer resources to benefit mankind.
Thoughts about SETI and SETI@home
1a) Yes.
2a) I think that if we are not alone in this universe, the beings that could find us would not need a method from us to find us.
3a) It's cool and makes my kids wonder about me.
