Ray Kurzweil Says Get ready for Hybrid Thinking

Futurist Ray Kurzweil suggests we should get ready for the next big leap in brain power, as we tap into the computing power in the cloud.

Two hundred million years ago, our mammal ancestors developed a new brain feature: the neocortex. This stamp-sized piece of tissue (wrapped around a brain the size of a walnut) is the key to what humanity has become.

Now, futurist Ray Kurzweil suggests, we should get ready for the next big leap in brain power, as we tap into the computing power in the cloud.

In the talk , Kurzweil author of How to Create a Mind, tells how the Cretaceous Extinction Event 65 million years ago wiped out 75 percent of animals and plants on Earth including the dinosaurs, “mammals overtook their ecological niche” and their brains became their evolutionary advantage. Today the neocortex so big it constitutes 80 percent of the human brain.

"Search engines will be based on combinations of words and links but will actually read the billions of pages on the web for understanding."

According to Kurzweil’s new theory, the brain is made up of 300 million modules. Each one learns, recognizes and implements a pattern, and all the modules are arranged in hierarchies created by our own thinking. This is how it works: One module in your mind might recognize the crossbar in the capital letter A. Its job is to recognize that and only that crossbar. It sends signals of high probability to the next level, which recognizes “A,” and then to the next level, which recognizes the written word “Apple.” You might go up ten levels and get a level that recognizes irony; but while hierarchy structures vary in complexity, in fact individual modules don’t function differently on a basic level.

Now, computers, says Kurzweil, are beginning to master human language with techniques similar to neocortex. In five to 10 years, he says, “search engines will be based on combinations of words and links but will actually read the billions of pages on the web for understanding.”

He says, while you’re on the Internet, something will pop up and say, “You expressed concern a few weeks ago about your gluten levels, and a new paper has just come out 10 seconds ago about it. Let me summarize it for you … .“ Kurzweil predicts that in 20 years nano-bots will enter the brain through capillaries to connect us to a synthetic neocortex in the cloud. So if someone walks past you whom you want to impress, but your 300 million modules aren’t enough to come up with something clever to say, all you need to do is tap into the neocortex in the cloud and another billion modules will become available. The future human, says Kurzweil, will be a biological and nonbiological hybrid.

Two million years ago when we developed large foreheads, it was a quantitative increase that led to a vast qualitative explosion – of art, culture and technology. In the next few decades, Kurzweil predicts, we’re going to do it again: And this time, “We won’t be limited by the fixed architecture of the enclosure. We will expand without limits.”
