That said, I believe we're the only intelligent life in our light-cone. Although Hanson makes a strong argument that we're just early and will run into intelligence in a billion years or so.
But it's possible they've run into us already. Not that I believe "contact" will ever happen, that's more for similarly intelligent species. I would argue if our average IQ was near 300 and we weren't the war apes 2.0 we are it might have happened.
