Are We Overthinking the Dangers of Artificial Intelligence?

Are We Overthinking the Dangers of Artificial Intelligence? | cognition | Scoop.it
Futurists and science fiction authors often give us overly grim visions of the future, especially when it comes to the Singularity and the risks of artificial superintelligence. Scifi novelist David Brin talked to us about why these dire predictions are often simplistic and unreasonable.

Consciousness: Why we need to build sentient machines - life - 25 May 2013 - New Scientist

FastTFriend's insight:

Trying to create a machine that experiences pain or colours in the same way that we do might require a radical rethink. Pentti Haikonen, an electrical engineer and philosopher at the University of Illinois in Springfield, believes that we will never create a feeling machine using software. Software is a language, he says, and so requires extra information to be interpreted. If you don't speak English, the words "pain" or "red", for instance, are meaningless. But if you see the colour red, that has meaning no matter what your language.

Most computers and robots created so far run on software. Even if they connect to a physical device, like a microphone, the input has to be translated into strings of 1s and 0s before it can be processed. "Numbers do not feel like anything and do not appear as red," says Haikonen. "That is where everything is lost."

Not so for Haikonen's robot. His machine, called XCR for experimental cognitive robot, stores and manipulates incoming sensory information, not via software, but through physical objects – in this case wires, resistors and diodes. "Red is red, pain is pain without any interpretation," says Haikonen. "They are direct experiences to the brain."

Turing test beaten for first time by virtual 13-year-old boy

Turing test beaten for first time by virtual 13-year-old boy | cognition | Scoop.it
'Eugene Goostman' fools 33% of interrogators into thinking it is human, in what is seen as a milestone in artificial intelligence
FastTFriend's insight:

No computer had ever previously passed the Turing test, which requires 30% of human interrogators to be duped during a series of five-minute keyboard conversations, organisers from the University of Reading said.

New Test for Computers: Grading Essays at College Level

New Test for Computers: Grading Essays at College Level | cognition | Scoop.it
A system developed by a joint venture between Harvard and M.I.T. uses artificial intelligence to assess student papers and short written answers, freeing instructors for other tasks.
FastTFriend's insight:

Imagine taking a college exam, and, instead of handing in a blue book and getting a grade from a professor a few weeks later, clicking the “send” button when you are done and receiving a grade back instantly, your essay scored by a software program. And then, instead of being done with that exam, imagine that the system would immediately let you rewrite the test to try to improve your grade.


EdX, the nonprofit enterprise founded by Harvard and the Massachusetts Institute of Technology to offer courses on the Internet, has just introduced such a system and will make its automated software available free on the Web to any institution that wants to use it. The software uses artificial intelligence to grade student essays and short written answers, freeing professors for other tasks.
