In his follow-up to Sapiens, Yuval Noah Harari envisions what a 'useless class' of humans might look like as AI advances and spreads - "I'm aware that these kinds of forecasts have been around for at least 200 years, from the beginning of the Industrial Revolution, and they never came true so far. It's basically the boy who cried wolf, but in the original story of the boy who cried wolf, in the end, the wolf actually comes, and I think that is true this time." [more inside]
Sapiens: A Brief History of Humankind by Yuval Noah Harari - "The book delivers on its madly ambitious subtitle by in fact managing to cover key moments in the developmental history of humankind from the emergence of Homo Sapiens to today's developments in genetic engineering." Also btw, check out Harari on the myths we need to survive, re: fact/value distinctions and their interrelationships.
The intelligence of octopuses is increasingly recognized, but nature is more creative than us glorified chimps ever realize on first blush. You see, octopuses are just full of neurons, but their nervous structure raises all kinds of uncanny questions--What is "intelligence" for an octopus? What is it like to be an octopus?--because most of them are in its arms. [more inside]
You invest so much in it, don't you? It's what elevates you above the beasts of the field, it's what makes you special. Homo sapiens, you call yourself. Wise Man. Do you even know what it is, this consciousness you cite in your own exaltation? Do you even know what it's for?Dr. Peter Watts is no stranger to MetaFilter. But look past his sardonic nuptials, heartbreaking eulogies, and agonizing run-ins with fascists (and fasciitis) and you'll find one of the most brilliant, compelling, and disquieting science fiction authors at work today. A marine biologist skilled at deep background research, his acclaimed 2006 novel Blindsight [full text] -- a cerebral "first contact" tale led by a diverse crew of bleeding-edge post-humans -- is diamond-hard and deeply horrifying, wringing profound existential dread from such abstruse concepts as the Chinese Room, the Philosophical Zombie, Chernoff faces, and the myriad quirks and blind spots that haunt the human mind. But Blindsight's last, shattering insight is not the end of the story -- along with crew/ship/"Firefall" notes, a blackly funny in-universe lecture on resurrecting sociopathic vampirism (PDF - prev.), and a rigorously-cited (and spoiler-laden) reference section, tomorrow will see the release of
Swimming around in a mixture of language and matter, humans occupy a particular evolutionary niche mediated by something we call 'consciousness'. To Professor Nicholas Humphrey we're made up of "soul dust": "a kind of theatre... an entertainment which we put on for ourselves inside our own heads." But just as that theatre is directed by the relationship between language and matter, it is also undermined by it. It all depends how you think it.
Sea Squirt Regrows Entire Body from One Blood Vessel. Most famous as the creature that settles down and eats its own brain (though that is not exactly correct), it appears the humble sea squirt has spectacular regenerative abilities as well, thanks to regeneration niches packed with stem cells. All glory to the sea squirt!
Blue Gene bears Blue Brain beats Deep Blue. Dr. Henry Markram answers questions in the FAQ. Neurons are beautiful. Blue Gene/L is now the fastest supercomputer in the world. IBM Research rocks. Deep Blue beat Kasparov almost a decade ago. Feeling Blue?
The first Transhuman Conference On the Law of Transhuman Persons: Whether or not you believe humans are set to evolve into gods, or AI is destined to achieve self-awareness the idea of the Transhuman is a thought provoking concept. Philosophers have debated the nature of the self, of the human for millennia. Is it time to start drafting new laws to govern all possible sentient beings on this planet? or is it all just a science of fiction? a comfortable humanist illusion?
We are because of others. We are born into this world with minds as naked as our bodies and we have to rely on others to feed, clothe us, and to teach us to think of ourselves as selves. The key is language -- grammatical speech and human culture build upon the brain's biological capacities to create a mind that is something different again than that with which we are born. We are conscious because we can speak to others and ourselves, because we can speak of ourselves to others and ourselves. Language gives us as individuals, memory, and as groups, culture, the social memory. Or so thought Lev Semyonovich Vygotsky, among others. Welcome to the the neuronaut's guide to the science of consciousness.
What am I? Clearly the most pressing question facing the human race today. Every individual human brain contains around 10^12 (1 trillion) neurons and 10^15 (1 quadrillion) synapses, capable of changing in milliseconds, and there are 6x10^9 (6 billion) people on this planet, all potentially capable of interacting and influencing one another. Last year alone 1.6x10^11 (160 billion) minutes of international telephone calls were made between people talking at a rate of 120 to 150 words per minute.
