Singularity by IEE

Singularity by IEE

Rapture for geeks. Just finished Fire Upon the Deep by Vinge.

“Why should a mere journalist question Kurzweil’s conclusion that some of us alive today will live indefinitely? Because we all know it’s wrong. We can sense it in the gaping, take-my-word-for-it extrapolations and the specious reasoning of those who subscribe to this form of the singularity argument. Then, too, there’s the flawed grasp of neuroscience, human physiology, and philosophy. Most of all, we note the willingness of these people to predict fabulous technological advances in a period so conveniently short it offers themselves hope of life everlasting.”

Why Vinge thinks it will happen:

In that event, I expect the singularity will come as some combination of the following:

The AI Scenario: We create superhuman artificial intelligence (AI) in computers.

The IA Scenario: We enhance human intelligence through human-to-computer interfaces—that is, we achieve intelligence amplification (IA).

The Biomedical Scenario: We directly increase our intelligence by improving the neurological operation of our brains.

The Internet Scenario: Humanity, its networks, computers, and databases become sufficiently effective to be considered a superhuman being.

The Digital Gaia Scenario: The network of embedded microprocessors becomes sufficiently effective to be considered a superhuman being.

The network is the brain

The network is the brain

This is the machine that led to the big brain: NMDA receptor complex (NRC/MASC), that is found at the synapses in the central nervous system which constitute the functional connections between neurons from Genes2Cognition.I put them into wikipedia here

Other interesting groups involved in the discovery that the complex proteins in the synapse connections were the key to our big ole brains were the Institute for Adaptive and Neural computing which studies three main areas: Bioinformatics, Machine Learning and Neuroinformatics and the Keele Institute, a school started the year before I was born to promote interdisciplinary and multi-disciplinary scholarship. It’s Institute for Science and Technology in Medicine bridges the interface between new advances in basic science and technology with medicine and clinical practice, bringing together engineers, mathematicians, biologists, physicists and clinicians, all in a single unit.

Big switch, big brains

A new study shows that it’s complex proteins that distinguishes more highly evolved brains. The evolution of molecularly complex, ‘big’ synapses occurred before the emergence of large brains, so it may be that these molecular evolutionary events were necessary to allow evolution of big brains found in humans, primates and other vertebrates.

The molecular evolution of the synapse is like the evolution of computer chips – the increasing complexity has given them more power and those animals with the most powerful chips can do the most.

Responses to the study here and other reports here and here and the study itself in Nature Neuroscience here.

The heart of what they found that led to the evolution of our brains was “a marked changes in signaling complexity.” The brain: it’s about the network.
