Life Sentence: Immortality


Ray Kurzweil and Peter Thiel are not crackpots.  

Kurzweil, among other things, was a major pioneer in speech recognition software and electronic musical instruments, from which he made a fortune.   Kurzweil still works in the music field on SONY projects, but his passion is … immortality, and he’s working hard towards that end.

Thiel has made a king’s fortune in online projects like EBAY and PayPal, but he’s got more innovative things up his sleeve.   Like Kurzweil, Theil’s looking to help fund the holy grail of humanity – immortality.

Even a few decades ago reasonable people would have considered much of the talk about a technological singularity and massive superintelligent computers to be fanciful at best and insanity at worst, but the inexorable march of technology is bringing us to within about a decade – probably two at the most – of human quality artificial intelligence.   The processing power of the human brain will be reached soon, and unless there is something more to our human intellect than one can reasonably assume we are going to be chatting intelligently with our computers fairly soon.  After that milestone is reached it is likely that it won’t be long before “recursive self improvement” by these intelligent computers will create artificial intelligences far superior to our current human intellects.  Not to worry though, because it also appears likely that improvements in medicine, brain research, and nanotechnology will allow us to enhance our bodies and intellects such that we’ll live much longer and be much smarter.

Kurzweil, in the book “The Singularity is Near”, argues that the historical exponential growth of technology shows no signs of slowing down – in fact he’s convinced the growth is speeding up.   At the current rates of increase we’ll see the same improvements over the next decades that we have seen in the past hundred years.  For Kurzweil these improvements will lead to a utopian future of no poverty, massively improved intellects, and eventually immortality as we download our brains into machines.

Sounds cool to me Ray, I’m IN!

What is “Intelligence” ?


Some good posts are popping up over the the Singularity Institute blog, though the discussions have been taking that odd “hostile academic” tone you often find from PhD wannabes who spend way too much time learning how to reference obvious things in obscure ways.

Michael Anissimov asked over there “What is Intelligence” and offered up a definition that could apply to human as well as artificial intelligence.    

I would suggest that intelligence is overrated as part of our evolutionarily designed, self-absorbed human nature, and in fact is best studied as separate from the states of “consciousness” and “self awareness” that are harder to define.    I think computers – and even a simple calculator – have degrees of intelligence but they do not have consciousness or self awareness.    It is these last two things that make humans think we are so very special.    I’d say consciousness is neat but probably a simpler thing than we like to …. um … think about.

Over there I wrote this in response to Michael’s post:

My working hypothesis about “intelligence” is that it is best viewed and defined in ways that separate it from “consciousness”.  I’d say intelligence is best defined such that it can exist without consciousness or self-awareness.   Thus I’d refer to a computer chess program as intelligent, but not conscious or self aware. 

I would suggest that intelligence is a prerequisite for consciousness which is a prerequisite for self-awareness, but separating these three things seems to avoid some of the difficulties of explanations that get bogged down as we try to develop models of animal and non-animal intelligence.  Also, I think this will describe the development curve of AIs which are already “intelligent”, but none are yet “conscious” or “self aware”.   I think consciousness may turn out to be simply a *massive number* of  interconnections carrying on intelligent internal conversations within a system – human or AI.

A stumbling block I find very interesting is the absurd notion that human intelligence is fundamentally or qualitatively different from other animal intelligences.   Although only a few other species appear to have self-awareness, there are many other “conscious” species and millions of “intelligent” species

A good question about intelligence is “WHY is intelligence”.   The obvious answer is evolutionary adaptivity, which in turn helps explain why our brains are so good at some things and so bad at others.  e.g. Human survival was more a function of short term planning rather than long term planning, so as you’d expect we are pretty good short term planners (“Let’s eat!”  “Let’s make a baby!”  “Look out for that car!) and pretty bad long term planners (Let’s address Social Security shortfalls!, “Let’s fix Iraq!)

Why “recursive self improvement” could be the key to enlightenment.


This excellent article by Michael Anissimov describes two versions of how things could shake out in the coming Artificial Intelligence revolution, and suggests that it’s more likely strong AI (that is, computer-like devices that think pretty much like we do) will lead to an explosive increase in intelligence as a result of “recursive self improvement”.    The idea is that the intelligent machines will operate much faster than our brains can function, but will also tend to improve on their own designs.  

For humanity, design improvements on our brain architecture have been a very-very slow process governed primarily by evolutionary challenges.  Basic analytical intelligence almost certainly emerged in animals as an adaptive advantage in terms of survival.   Unlike our cousins the higher apes, human brain power has combined with community history to allow us to build technologies that last through many generations, and more importantly to *improve* as new people grapple with new problems.  This technological explosion is a fairly recent phenomenon but should still be considered a very slow process compared to the type of progress you would expect to see in an environment driven purely towards advancing the technologies surrounding “intelligence”.

If Anissimov and many others in strong AI research are correct, the time between the advent of conscious, recursively self improving computers and a massive explosion of intelligent machines could be very small – a few years or even possibly just a few moments.    

Currently, we humans do a handful of physical transformations that take us off of the slow evolutionary treadmill.   Glasses are a simple technology that changes us.   Corneal transplant and heart stints are “advanced” technological enhancments to our bodies.    Cell phones and computers are technological enhancements to our brains (and yes, the company called “BrainGate” has now connected computer chips directly to brains allowing human brains to directly interface with computers to do simple tasks).   

Still,  earth’s painstakingly slow evolutionary processes has yet to develop a creature that will be able to rebuild itself every few days into a vastly superior version of the former self.   We appear to be within a few  decades of that type of entity.

The implications of this re-evolutionary development cannot be overestimated.
