  • SETI senior astronomer Seth Shostak says we should expand our search for extraterrestrial life to include sentient alien machines. 
  • According to Shostak, if we can develop artificial intelligence within a couple 100 years of inventing radio, any aliens we are likely to hear from have likely gone past that point.

Reddit comment:

Accelerando had a great take on this idea. (IIRC) Virtual humans are uploaded into a spacecraft the size of a soda can, attached to a massive solar sail, and sent to a nearby wormhole, pushed along by a laser. They encounter aliens who are also virtual.
