You aren't alone in your assertion that machine intelligence will replace humans within that basic narrative. Hugo de Garis is a artificial intelligence expert predicting the same thing. I can't help you get a hold of Larry Page (obviously) but I would love to help you get in touch with the right people. The "singularity" community is becoming quite well connected and the amount of money that is about to get directed towards anti-aging technology is going way up. I know a few people who know Aubrey de Grey and Ben Goertzel. Both would in principle be interested to hear the proposal. Let me know and I can try and set up something.I'd love to get the idea to Larry Page, because I think it is right up his alley, but that's a very difficult thing to do.
