Michio Kaku: Genetic and digital immortality are within reach

Technology may soon grant us immortality, in a sense. Here's how.

MICHIO KAKU: The rate at which we are learning about longevity Gives one pause. It makes you realize that perhaps digital and genetic immortality are Within reach. Already, in Silicon Valley, there are companies which, for a price, will digitize everything known about you your credit card transactions, your emails, Instagrams. Everything known about you can be digitized. And we have something called the Connectome Project, which will map the pathways of the entire human brain all your memories, all your quirks, personalities, everything digitized. And we'll put it on a disk. And for the most part, we'll put it in a library. Today, you go to the library, and you take a book out About Winston Churchill. In the future, you'll go to the library and talk to Winston Churchill, because all his speeches, his mannerisms, his memories, his letters, Have been digitized. I would love to talk to Einstein. I would love to talk to him, even if it's a computer program that has digitized everything known about him his work, his writings, His speeches, everything, and a holographic image, so that I can talk to him. And one day, we might be digitized, as well. We'll be able to talk to our great-great-great-great-great grandkids, and they'll be able to talk to their great-great-great-great-great Ancestors, as well. Because we become immortal. Not only that, but we're now beginning to isolate the genes which control the aging process. First of all, let's take a car. Where does aging take place in a car? Aging takes place in the engine. Why? That's where you have moving parts and combustion. Well, where, in the cell, do we have the power house of a cell? Mitochondria. Bingo, we now know where most of the errors build up in a cell. And with CRISPR technology, we may be able to edit out the errors that build up and extend the human lifespan. For example, a mouse can live to be about roughly two years of age, and then it dies of old age. But the Greenland shark can live to be over 400 years of age. And that's just not hearsay. By looking at the eyeball of the Greenland shark, it adds layers at a very precise rate in the eye. By analyzing and counting the layers, we see that the Greenland shark can live almost 500 years in age. So in other words, genetically speaking, it may be possible to extend the human lifespan. So genetic and biological immortality are definitely in the cards.
  • Through the Connectome Project we may soon be able to map the pathways of the entire human brain, including memories, and create computer programs that evoke the person the digitization is stemmed from.
  • We age because errors build up in our cells — mitochondria to be exact.
  • With CRISPR technology we may soon be able to edit out errors that build up as we age, and extend the human lifespan.

This nerd fight could wreck or cure our way of life

It's economists vs. climate scientists in this facet of the climate change debate.

Surprising Science
  • What climate scientists have called a Hothouse Earth emergency, has been called "optimal" by a leading economist.
  • That optimal scenario is based on "the most unrealistic and dangerous assumption in the history of economics."
  • Leading scientists warn strongly against the methods that economists use. "No amount of economic cost–benefit analysis is going to help us. We need to change our approach."
