The Panspermia Theory.
"Ray Kurzweil is a prominent futurist who wholeheartedly believes that in the coming decades humanity will experience what he refers to as a technological singularity by which we will learn to transcend biology itself and all the limitations (including death) associated with it. Kurzweil reasons that truly intelligent civilizations (which he believes humanity to be) are destined to evolve into super-intelligent, possibly machine-based beings whose computational powers grow exponentially.
The idea is that once we hit this so-called “singularity” our technology will be so advanced that we’ll be making revolutionary new breakthroughs on practically a daily basis. We’ll be able to harness the power of our own sun in order to accomplish amazing interstellar feats once only dreamed of in science fiction. In this world, things like cyber brains, dyson spheres and teleportation devices aren’t just possible, they’re practically inevitable.
Of course, this theory has plenty of skeptics, including Noam Chomsky, who believes it to be nothing more than a science fiction enthusiast’s dream. While others simply believe we humans will carelessly destroy ourselves before ever reaching the singularity."
