Michio Kaku: Alien Laser Superhighway and Digital Immortality | AI Podcast Clips
00:00:00.000 | And so I think that we are going to digitize ourselves and give us digital immortality.
00:00:07.000 | We'll not only have biologic genetic immortality of some sort, but also digital immortality.
00:00:13.980 | And what are we going to do with it?
00:00:15.960 | I think we should send it into outer space.
00:00:19.940 | If you digitize the human brain and put it on a laser beam and shoot it to the moon,
00:00:25.640 | you're on the moon in one second.
00:00:27.920 | Shoot it to Mars, you're on Mars in 20 minutes.
00:00:31.000 | Shoot it to Pluto, you're on Pluto in eight hours.
00:00:33.840 | Think about it for a moment.
00:00:35.140 | You can have breakfast in New York and for a morning snack, vacation on the moon, then
00:00:41.320 | zap your way to Mars by noontime, journey to the asteroid belt in the afternoon, and
00:00:47.560 | then come back for dinner in New York at night.
00:00:51.120 | All in a day's work.
00:00:52.440 | At the speed of light.
00:00:55.100 | Now this means that you don't need booster rockets, you don't need weightlessness problems,
00:01:00.680 | you don't need to worry about meteorites.
00:01:02.720 | And what's on the moon?
00:01:04.400 | On the moon, there is a mainframe that downloads your laser beam's information.
00:01:10.100 | And where does it download the information into?
00:01:12.960 | An avatar.
00:01:13.960 | And what does that avatar look like?
00:01:17.040 | Anything you want.
00:01:20.000 | Think about it for a moment.
00:01:21.000 | You could be Superman, Superwoman, on the moon, on Mars, traveling throughout the universe
00:01:28.140 | at the speed of light, downloading your personality into any vehicle you want.
00:01:34.200 | Now let me stick my neck out.
00:01:36.160 | So far everything I've been saying is well within the laws of physics.
00:01:39.840 | Well within the laws of physics.
00:01:41.440 | Now let me go outside the laws of physics again.
00:01:43.640 | Here we go.
00:01:44.640 | I think this already exists.
00:01:47.680 | I think outside the earth there could be a superhighway, a laser highway, of laser porting
00:01:53.600 | with billions of souls of aliens zapping their way across the galaxy.
00:01:59.840 | Now let me ask you a question.
00:02:01.600 | Are we smart enough to determine whether such a thing exists or not?
00:02:07.080 | No.
00:02:08.200 | This could exist right outside the orbit of the planet earth.
00:02:11.920 | And we're too stupid in our technology to even prove it or disprove it.
00:02:17.720 | We would need the aliens on this laser superhighway to help us out, to send us a human interpretable
00:02:28.600 | signal.
00:02:29.600 | I mean, it ultimately boils down to the language of communication, but that's an exciting possibility
00:02:33.720 | that actually the sky is filled with aliens.
00:02:37.920 | It could already be here and we're just so oblivious that we're too stupid to know it.
00:02:43.840 | See, they don't have to be in alien form with little green men.
00:02:48.640 | They can be in any form they want, in an avatar of their creation.
00:02:51.760 | Well, in fact, they could very well be-
00:02:53.920 | They could even look like us.
00:02:56.320 | Exactly.
00:02:57.320 | We'd never know.
00:02:58.320 | One of us could be an alien.
00:03:00.160 | You know, in the zoo, did you know that we sometimes have zookeepers that imitate animals?
00:03:05.280 | We create a fake animal and we put it in so that the animal is not afraid of this fake
00:03:11.600 | animal.
00:03:12.600 | And of course, these animals' brains, their brain is about as big as a walnut.
00:03:15.960 | They accept these dummies as if they were real.
00:03:20.640 | So an alien civilization in outer space would say, "Oh yeah, human brains are so tiny.
00:03:25.400 | We could put a dummy on their world, an avatar, and they'd never know it."
00:03:30.600 | That would be an entertaining thing to watch from the alien perspective.
00:03:33.280 | Yeah.
00:03:34.280 | Yeah.
00:03:35.280 | Yeah.
00:03:35.280 | Yeah.
00:03:36.280 | Yeah.
00:03:36.280 | Yeah.
00:03:41.280 | Yeah.
00:03:46.280 | Yeah.
00:03:51.280 | You
