Darwin & Turing: The Evolution of Artificial Intelligence
What evolution and computer science have taught us is that comprehension is not required for competence. Similarly, the human mind may not be so mysterious as is often thought.
What's the Latest Development?
This weekend marks 100 years since the birth of Alan Turing, the English logician who successfully cracked Nazi coding machines during WWII. Having pioneered concepts like "algorithm" and "computation", Turing is considered one of the chief architects of early computing as well as what would become artificial intelligence. Daniel Dennett, philosophy professor at Tufts University, sees a remarkable similarity between the thought of Turing and Charles Darwin. Both realized, according to Dennett, that comprehension is not necessary to achieve competency. In other words, neither the process of evolution nor contemporary computers are self-aware, but they nonetheless perform complex operations extremely efficiently.
What's the Big Idea?
Dennett believes the idea that competency can be achieved without comprehension sheds light on our own conscious processes and helps to clarify the mind-body problem, i.e. how consciousness can arise from unconscious matter. "There is no principled line above which true comprehension is to be found," said Dennett, "even in our own case. The small child sorta understands her own sentence 'Daddy is a doctor,' and I sorta understand 'E=mc2.'" In other words, machines may not need to fully understand what "love" or "affection" mean in order to offer these condolences to humans, or to each other.

- Some are concerned about the proliferation of space debris in Earth's orbit.
Progressive America would be half as big, but twice as populated as its conservative twin.
Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.
- There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
- CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
- Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
- Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.
