Peering into the Future: AI and Robot brains

In Singularity or Transhumanism: What Word Should We Use to Discuss the Future? on Slate, Zoltan Istvan writes:

Singularity-word-cloud"The singularity people (many at Singularity University) don't like the term transhumanism. Transhumanists don't like posthumanism. Posthumanists don’t like cyborgism. And cyborgism advocates don't like the life extension tag. If you arrange the groups in any order, the same enmity occurs." 

See what the proponents of these words mean by them...
...and why the old talmudic rabbis and jesuits are probably laughing their socks off.
==Progress toward AI?== 
Baby X, a 3D-simulated human child is getting smarter day by day. Researchers at the Auckland Bioengineering Institute Laboratory for Animate Technologies in New Zealand interact with the simulated toddler, reading, teaching, smiling, playing games, even singing into the computer's microphone and webcam. The blonde youngster mimics facial expressions, laughs, reads words, even cries when he is left alone.
1400832509352"An experiment in machine learning, Baby X is a program that imitates the biological processes of learning, including association, conditioning and reinforcement learning. By algorithmically simulating the chemical reactions of the human brain— think dopamine release or increased oxytocin levels— and connecting them with sensory digital input, when Baby X learns to imitate a facial expression, for instance, software developers write protocols for the variable time intervals between action and response. Effectively "teaching" the child through code, while engineering such a program is no cakewalk, the result is an adorably giggling digital baby with an uncanny ability to learn through interaction," writes Becket Mufson, in the Creators Project.
This is precisely the sixth approach to developing AI that is least discussed by “experts” in the field… and that I have long believed to be essential, in several ways. Above all, by raising them as our children – even fostering them to homes in small robot bodies – we will gain many crucial advantages – that I lay out (somewhat) in Existence.
Meanwhile, Cornell's Robo Brain is currently learning from the internet -- downloading and processing about 1 billion images, 120,000 YouTube videos, and 100 million how-to documents and appliance manuals, all being translated and stored in a robot-friendly format, accessible to 'helper' robots who will function in our factories, homes, and offices. “If a robot encounters a situation it hasn’t seen before it can query Robo Brain in the cloud,” said one researcher. Follow its progress on the Robobrain website.

It's coming. "You can call it a Virtual Personal Assistant, an Intelligent Agent, an Intelligent Interface or whatever you wish. We call it inevitable," writes Dag Kitlaus in A Cambrian Explosion in AI is Coming in TechCrunch. An interesting assessment of the era of the digital assistant and the likely tsunami of new variations, building upon variations.
Meet Jibo, advertised as "the world's first family robot." Kinda creepy but attractive too…
Asimov-three-laws-roboticsEver hear of “neuromorphic architecture?” Silicon chip design that uses transistors — (5 billion of them in the latest IBM chip) - to create analogues of the nonlinear response patterns of biological neurons. The latest version, from IBM, is called “True North” and it is simply spectacular. Its prodigious pattern recognition capabilities are only matched by its stunning (by four orders of magnitude(!)) power efficiency. This is where Moore’s Law, augmented by new neuronal and parallelism software, may truly start delivering.
Now… How to keep what we produce sane? And where on the chip - pray tell - do the Three Laws reside?
Ah, well… I have explored the implications (yin and yang) of the Asimovian laws in my sequel which tied up all the loose ends in Isaac’s universe – Foundation's Triumph. Meanwhile, serious minds are grappling with the problem of “how to keep them loyal." For example…
==Creating Superintelligence==
"Risks that are especially difficult to control have three characteristics: autonomy, self-replication and self-modification. Infectious diseases have these characteristics, and have killed more people than any other class of events, including war. Some computer malware has these characteristics, and can do a lot of damage...
"But microbes and malware cannot intelligently self-modify, so countermeasures can catch up. A superintelligent system [as outlined by Bostrom would be much harder to control if it were able to intelligently self-modify." writes Bostrom.
Nick Bostrom makes a persuasive case that the future impact of AI is perhaps the most important issue the human race has ever faced. Instead of passively drifting, we need to steer a course. Still, his litany of “be careful what you wish for” parables is taken straight from the pages of a century of science fictional “what-if” scenarios. Geeky sci fi archivists need to be present, during the programming, to point out: “you may want to rephrase that… cause way back in 1947 Leigh Brackett showed that it could be misconstrued as...”
== and more on "intelligence..." ==

When did homo sapiens become a more sophisticated species? Not until our skulls underwent “feminization." Interesting article! In fact the mystery of the First Great Renaissance... the burst of human creativity around 45,000 years ago... is discussed in EXISTENCE!
But -- if I may mention it -- the real correlation with this notion… that sexual selection resulted in gentler, more “feminized” males, was presaged by this paper of mine… Neoteny and Two-Way Sexual Selection in Human Evolution.
==Developing Brains==
EMPATHYResearcher Talma Hendler has found evidence for two types of empathy, each tied to a different network of brain regions. One type she calls mental empathy, which requires you to mentally step outside yourself and think about what another person is thinking or experiencing. Parts of the frontal, temporal, and parietal cortex that make up this network. The other type she calls embodied empathy; this is the more visceral in-the-moment empathy you might feel when you see someone get punched in the guts. Very cogent and thought provoking.
This interesting article in Wired explores how movies exploit both of these networks to make you identify with the characters. Only the manipulation is now going scientific!
And veering a bit... When did modern humans arrive in Europe, and by how much did they overlap with our fading cousins, the Neandertals? New studies suggest it all happened earlier than most had assumed, perhaps around ...45,000 years ago.
Now throw in.... Children and adolescents with autism have a surplus of synapses in the brain, and this excess is due to a slowdown in a normal brain “pruning” process during development.
Hmmmmm.
==and organs==
Scientists have for the first time grown a complex, fully functional organ from scratch in a living animal by transplanting cells that were originally created in a laboratory to form a replacement thymus, a vital organ of the immune system.
By deciphering the detailed gene expressions by which a lizard regrows its tail, scientists hope to re-ignite regrowth processes in mammals like us, that have been dormant for 200 million years.

 Both of these stories are straight from my story “Chrysalis” in this month’s ANALOG! Have a look and see where all this may lead!
==Miscellanea==
Scientists report using laser light in ultrafast pulses to control the quantum state of electrons contained inside nanoscale defects located in a diamond, and also observe changes in that electron over a period of time. The findings could be an important milestone on the road to quantum computing.
SCIENCE-TECHNOLOGYAnother team has devised a way to make microscopes magnify 20 times more than usual. This magnification allows scientists to see and identify substances and matter as minuscule as or even smaller than a virus.
Direct synthesis of ammonia from air and water? At low temperatures and pressures? If this membrane method can bypass the usual harsh processes, the news can be significant for liberating poor farmers everywhere to make their own fertilizer.
Looks plausible… if amazing! A transparent luminescent solar concentrator developed in Michigan can be used to cover anything that has a flat, clear surface. Visible light passes through. But organic molecules absorb invisible wavelengths of sunlight such as ultraviolet and near infrared, guiding those packets to the edge of the solar panel, where thin strips of photovoltaic solar cells pick it up and convert it into energy. Fascinating… another potential game changer.

Researchers from UC San Diego's structural engineering department are using drones to capture unique views of the earthquake damage to Napa's historic landmarks. Our own Falko Kuester explains how this new tech is helping.


How to tell if a Chelyabinsk style meteorite came from an asteroid? Here's the basic rule of thumb. “The speed of whatever collides with Earth’s atmosphere depends on its orbit, which in turn depends on its source. The impactor’s entry at 19 km/s means that it came from the asteroid belt between Mars and Jupiter, not from a ballistically launched missile, whose speed is less than 11.2 km/s; a short-period comet, with an average speed of 35 km/s; or a long-period comet with an average speed of 55 km/s. As investigators began retracing the path of the meteor that blazed across the sky, their reconstructed orbit bore out that provenance.”  
Oh, anything much faster than 60 kps either fall naturally from outside the solar system... or was accelerated by someone with boojum powers and maybe ill intent!
And finally:
Don’t bogart that puffer, my friend. Dolphins pass around a puffer fish — apparently to get high off its toxins. After a few chomps, you no longer give a fugu.

The Real Way to Feel Safe with Artificial Intelligence

Sorry to have posted so little, of late.  We have been ensnared by a huge and complex Eagle Scout Project here... plus another kid making Black Belt, and yet another at Screenwriting camp... then the first one showing me endless online photos of "cars it would be cool to buy..."

And so, clearing my deck of topics to rant about, I'd like to post quickly this rumination on giving rights to artificial intelligences.  Bruce Sterling has lately raised this perennial issue, as did Mike Treder in an excellent piece suggesting that our initial attitudes toward such creatures may color the entire outcome of a purported "technological singularity."

==The Real Reason to Ensure AI Rights==

51NF4AW47EL._SL500_AA300_No issue is of greater importance than ensuring that our new, quasi-intelligent creations are raised properly.  While oversimplifying terribly, Hollywood visions of future machine intelligence range from TERMINATOR-like madness to admirable traits portrayed in movies like AI or in the BICENTENNIAL MAN.

I've spoken elsewhere of one great irony -- that there is nothing new about this endeavor.  That every human generation embarks upon a similar exercise -- creating new entities that start out less intelligent and virtually helpless, but gradually transform into beings that are stronger, more capable, and sometimes more brilliant than their parents can imagine.

The difference between this older style of parenthood and the New Creation is not only that we are attempting to do all of the design de novo, with very little help from nature or evolution, but also that the pace is speeding up. It may even accelerate, once semi-intelligent computers assist in fashioning new and better successors.

Humanity is used to the older method, in which each next generation reliably includes many who rise up, better than their ancestors... while many others sink lower, even into depravity.  It all sort of balanced out (amid great pain), but henceforth we cannot afford such haphazard ratios,  from either our traditional-organic heirs or their cybernetic creche-mates.

The_Matrix_PosterI agree that our near-future politics and social norms will powerfully affect what kind of "singularity" transformation we'll get -- ranging from the dismal fears of Bill Joy and Ted Kaczynski to the fizzing fantasies of Ray Kurzweil.  But first, let me say it's not the surface politics of our useless, almost-meaningless so-called Left-vs-Right axis. Nor will it be primarily a matter of allocation of taxed resources. Except for investments in science and education and infrastructure, those are not where the main action will be.  They will not determine the difference between "good" and "bad" transcendence.  Between THE MATRIX  and, say, FOUNDATION'S TRIUMPH.

No, what I figure will be the determining issue is this.  Shall we maintain momentum and fealty to the underlying concepts of the Western Enlightenment? Concepts that run even deeper than democracy or the principle of equal rights, because they form the underlying, pragmatic basis for our entire renaissance.

==Going With What Has Already Worked==

These are, I believe, the pillars of our civilization -- the reasons that we have accomplished so much more than any other, and why we may even succeed in doing it right, when we create Neo-Humanity.

1.  We acknowledge that individual human beings  -- and also, presumably, the expected caste of neo-humans -- are inherently flawed in their subjectively biased views of the world.

In other words...  we are all delusional! Even the very best of us.  Even (despite all their protestations to the contrary) all leaders.  And even (especially) those of you out there who believe that you have it all sussed.

This is crucial. Six thousand years of history show this to be the one towering fact of human nature.  Our combination of delusion and denial is the core predicament that stymied our creative, problem-solving abilities, delaying the great flowering that we're now part-of.

These dismal traits still erupt everywhere, in all of us.  Moreover, it is especially important to assume that delusion and denial will arise, inevitably, in the new intelligent entities that we're about to create.  If we are wise parents, we will teach them to say what all good scientists are schooled to say, repeatedly: "I might be mistaken."  But that, alone, is not enough.

How-to-Create-a-Mind-cover-347x5122.  There is a solution to this curse, but it is not at all the one what was recommended by Plato, or any of the other great sages of the past.

Oh, they knew all about about the delusion problem, of course.  See Plato's "allegory of the cave," or the sayings of Buddha, or any of a myriad other sage critiques of fallible human subjectivity.  These savants were correct to point at the core problem... only then, each of them claimed that it could be solved by following their exact prescription for Right Thinking. And followers bought in, reciting or following the incantations and flattering themselves that they had a path that freed them of error.

Painfully, at great cost, we have learned that there is no such prescription. Alack, the net sum of "wisdom" that those prophets all offered only wound up fostering even more delusion.  It turns out that nothing -- no method or palliative applied by a single human mind, upon itself -- will ever accomplish the objective.

Oh, sure, logic and reason and sound habits of scientifically-informed self-doubt can help a lot.  They may cut the error rate in half, or even by a factor of a hundred!  Nevertheless, you and I are still delusional twits.  We always will be!  It is inherent.  Live with it.  Our ancestors had to live with the consequences of this inherent human curse.

Ah, but things turned out not to be hopeless, after all!  For, eventually, the Enlightenment offered a completely different way to deal with this perennial dilemma.  We (and presumably our neo-human creations) can be forced to notice, acknowledge, and sometimes even correct our favorite delusions, through one trick that lies at the heart of every Enlightenment innovation -- the processes called Reciprocal Accountability (RA).

In order to overcome denial and delusion, the Enlightenment tried something unprecedented -- doing without the gurus and sages and kings and priests.  Instead, it nurtured competitive systems in markets, democracy, science and courts, through which back and forth criticism is encouraged to flow, detecting many errors and allowing many innovations to improve.  Oh, competition isn't everything! Cooperation and generosity and ideals are clearly important parts of the process, too. But ingrained reciprocality of criticism -- inescapable by any leader -- is the core innovation.


3.  These systems -- including "checks and balances" exemplified in the U.S. Constitution -- help to prevent the kind of sole-sourcing of power, not only by old-fashioned human tyrants, but also the kind of oppression that we all fear might happen, if the Singularity were to run away, controlled by just one or a few mega-machine-minds. The nightmare scenarios portrayed in The Matrix, Terminator, or the Asimov universe.

==The Way to Ensure AI is Both Sane and Wise==

KurzweilSingularityCoverHow can we ever feel safe, in a near future dominated by powerful artificial intelligences that far outstrip our own? What force or power could possibly keep such a being, or beings, accountable?

Um, by now, isn't it obvious?

The most reassuring thing that could happen would be for us mere legacy/organic humans to peer upward and see a great diversity of mega minds, contending with each other, politely, and under civil rules, but vigorously nonetheless, holding each other to account and ensuring everything is above-board.

This outcome -- almost never portrayed in fiction --  would strike us as inherently more likely to be safe and successful.  After all, isn't it today's situation?  The vast majority of citizens do not understand arcane matters of science or policy or finance.  They watch the wrangling among alphas and are reassured to see them applying accountability upon each other.... a reassurance that was betrayed by recent attempts to draw clouds of secrecy across all of our deliberative processes.

Sure, it is profoundly imperfect, and fickle citizens can be swayed by mogul-controlled media to apply their votes in unwise directions.  We sigh and shake our heads... as future AI Leaders will moan in near-despair over organic-human sovereignty.  But, if they are truly wise, they'll continue this compact.  Because the most far-seeing among them will recognize that "I might be wrong" is still the greatest thing than any mind can say.  And that we reciprocal criticism is even better.

SoYouWantToMakeGodsAlas, even those who want to keep our values strong, heading into the Singularity Age, seldom parse it down to this fundamental level.  They talk - for example - about giving AI "rights" in purely moral terms...  or perhaps to placate them and prevent them from rebelling and squashing us.

But the real reason to do this is far more pragmatic.  If the new AIs feel vested in a civilization that considers them "human" then they may engage in our give and take process of shining light upon delusion. Each others delusions, above all.

Reciprocal accountability -- extrapolated to a higher level -- may thus maintain the core innovation of our civilization: its central and vital insight.

And thus, we may find that our new leaders -- our godlike grandchildren -- will still care about us... and keep trying to explain.

News From Science 'n Stuff

Next year it will be 25 years after "1984" - is there anything planned to celebrate it? The Science Fiction world managed 2007-07-07 to celebrate Heinlein's 100th.

CrystalSpheresNewestCheck out the the StarShipSofa site, where they have some really terrific podcasts of classic science fiction stories. They made an earnest effort to recite “The Crystal Spheres” -- though it’s a very hard story to do in audio, filled with combined-words that most readers need to eye scan a few times in order to grasp or put in context. Something most can do unconsciously, but cannot do in audio. That understood, this narrator does a fine job with this Hugo-winning story (also available on Kindle and Nook).

Wow! A robot in Kyoto, Japan, mimics a monkey walking on a treadmill (background) in North Carolina last week. Neuroscientist Miguel A. L. Nicolelis at Duke University says it is the first time that brain signals have been used to make a robot walk. Name him Waldo!

Chemical Robots (ChemBots): soft, flexible, mobile objects that can identify and maneuver through openings smaller than their static structural dimensions; reconstitute size, shape, and functionality after traversal; carry meaningful payloads; and perform tasks.

For those of you who have seen Cloverfield (also called the “Blair Godzilla Project”) try this appraisal of how smart and well prepared (CERT-trained?) people might have handled the same situation. (Thanks Stefan.)

Design guru Don Norman offers the following interesting tidbit: “Two thousand years ago, Socrates argued that the book would destroy people’s ability to reason. He believed in dialogue, in conversation and debate. But with a book, there is no debate: the written word cannot talk back. Today, the book is such a symbol of learning and knowledge that we laugh at his argument. But take it seriously for a moment. Despite Socrates’ claims, writing does instruct because we do not need to debate it with the author. Instead, we debate and discuss with one another, in the classroom, with discussion groups, and – if it is an important enough work – through all the media at our disposal: printed newspapers and magazines, radio and television, Internet websites and discussion boards. Nonetheless, his point is valid: a technology that gives no opportunity for discussion, explanation, or debate is a poor technology.”
