Alien hunters ‘should look for artificial intelligence’

The odds favor detecting alien AI rather than biological life because the time between aliens developing radio technology and artificial intelligence would be short, says SETI Institute senior astronomer Seth Shostak.
He also says that artificially intelligent alien life would be likely to migrate to places where both matter and energy — the only things he says would be of interest to the machines — would be in plentiful supply. That means the SETI hunt may need to focus its attentions near hot, young stars or even near the centers of galaxies.
