Will a computer ever be able to fully simulate a human brain? This £billion project reckons it will have some answers in 10 years time.

      True, the idea of building a brain similar to ours, is laughable, unless as Sal has said they get lucky!


      They would need their own power plant and a few thousand terabyte per second supercomputers to even get close to pulling it off!


      Obviously building it atom by atom would drastically reduce power and space needed, but without an intimate understanding of consciousness, or targeted universal energy it won't occur.

      Consciousness is just energy patterns, interacting with matter in such a way that matter can become self aware!

      Computers move electrical energy around, a big difference!

      hmmmmm!

    Biological machines will one day be a reality. Only then will you simulate human thought.

    Well, I saw articles such as the following even in the 1980s!

    https://news.uic.edu/a-computer-as-s...-four-year-old

    Artificial and natural knowledge researchers at the University of Illinois at Chicago have IQ-tested one of the best available artificial intelligence systems to see how intelligent it really is.

    Turns out–it’s about as smart as the average 4-year-old, they will report July 17 at the U.S. Artificial Intelligence Conference in Bellevue, Wash.
    BULL!!!!!!! A 4yo is ****SO**** intelligent that it could decode the language in spoken and written form and SO much more. To even ascertain that ability, let alone test it, is simply not possible, but still, there is no test for anything. Kids may be assessed by a HUMAN, and have a portion of the intelligence tested, but it is just a sampling.

    The UIC team put ConceptNet 4, an artificial intelligence system developed at M.I.T., through the verbal portions of the Wechsler Preschool and Primary Scale of Intelligence Test, a standard IQ assessment for young children.
    ****VERBAL****!?!?!?!? Why didn't the include the visual? Could it be because they knew it would FLUNK? And what of the math?

    They found ConceptNet 4 has the average IQ of a young child. But unlike most children, the machine’s scores were very uneven across different portions of the test.
    YEP! I'LL BET! Kind of blows their initial statement out of the water.

    “If a child had scores that varied this much, it might be a symptom that something was wrong,” said Robert Sloan, professor and head of computer science at UIC, and one of the study’s authors.
    Could that be any clearer?

    Sloan said ConceptNet 4 did very well on a test of vocabulary and on a test of its ability to recognize similarities.
    In OTHER words, it was a dictionary/thesaurus! REALLY!?!?!?!? "SCIENTISTS" think THAT is all the human brain is?

    “But ConceptNet 4 did dramatically worse than average on comprehension—the ‘why’ questions,” he said.
    OOOPS! IT FLUNKED!

    One of the hardest problems in building an artificial intelligence, Sloan said, is devising a computer program that can make sound and prudent judgment based on a simple perception of the situation or facts–the dictionary definition of commonsense.

    Commonsense has eluded AI engineers because it requires both a very large collection of facts and what Sloan calls implicit facts–things so obvious that we don’t know we know them. A computer may know the temperature at which water freezes, but we know that ice is cold.
    OOPS! TOTAL FAIL!!!!!!!!! A computer does NOT know water freezes! It accesses information FROM HUMANS that relays that water freezes! It is a KNOWN FACT that some humans simply LEARN before anyone even tells them! Computers don't even have the ability to make THAT simple discovery! SURE, we could have them stay in an area, remember the item was there, and lower the temperature and check it. But they are PROGRAMMED to make that discovery and how to make it.

    “All of us know a huge number of things,” said Sloan. “As babies, we crawled around and yanked on things and learned that things fall. We yanked on other things and learned that dogs and cats don’t appreciate having their tails pulled. Life is a rich learning environment.”
    EXACTLY!

    “We’re still very far from programs with common sense–AI that can answer comprehension questions with the skill of a child of 8,” said Sloan. He and his colleagues hope the study will help to focus attention on the “hard spots” in AI research.
    GEE! Computers have a LOT of benefits over humans! TENACITY! TIRELESS! PERFECT SITE! PERFECT HEARING! PERFECT MEMORY! SPEED on a particular task! If they REALLY made a computer 7/15/2013 that was as smart as a 4yo, it could EASILY be as smart as an 8yo before they met with the author to discuss the potential! So WHY didn't it happen? EASY! The computer was NOT as smart as a 4yo! They simply programmed it to do a ridiculously simple(for a computer) part of the test!
