Comment of the Day: “The Digital Revolution Will Make Human Civilization Invisible to Extraterrestrial Search"
"When you look at the current level at which our own technology is advancing, quantum computing, cloaking technology, robotics, nanotech, communications. It's not really such a far stretch to think that somewhere out there among the trillions of possible life harboring planets, that another intelligent civilization has done the same things. If they had even a 100 year head start on us they would already be so far advanced, now give them a 1000 year head start or even a 1 million year head start. Their technology would be so far in advance of our own.
"They could literally be here right now. Existing inside and outside of our known reality. Hidden only by a technological barrier. If they were a billion years older than our civilization i doubt we could even comprehend there technology. A type 3 civilization as Michio Kaku says would have the technology to harness the power of an entire galaxy. Who knows what a type 4 civilization would resemble. When you consider how short 1 million years is on a cosmic scale, its not out of the realm of possibilities."
