The Great Lifespan Escape

At the time when the lines begin, in the mid-18th century, life expectancy in Europe and the Americas was around 35, where it had been parked for the 225 previous years for which we have data.3 Life expectancy for the world as a whole was 29. These numbers are in the range of expected life spans for most of human history. The life expectancy of hunter-gatherers is around 32.5, and it probably decreased among the peoples who first took up farming because of their starchy diet and the diseases ...

 Freeman Dyson's Optimism

Brand: I was looking at your 1988 book, Infinite in All Directions, and remembering what it was that excited me about it. Ten years ago, most people I knew were in the depths of a kind of bad mood, harboring a pessimistic feeling that things were going to keep getting worse for the rest of their lives. But your book had this pragmatic and also rather cosmic optimism about it; it came as a complete counter to the cultural flow at that point. Did you perceive that at the time? Dyson: Oh yes. I...

 Static Culture

The fantasies of Wells and Huxley were based on the same idea, that a species adapting itself too perfectly to a static ecological niche is doomed to stagnation and ultimate extinction. Their nightmares describe a possible future for our species, if we succeed in building around ourselves a protective cocoon that shields us from the winds of change while our mental faculties dwindle. A future of senile dementia is as possible for the species as it is for the individual. And yet, when I compa...

 The Violent Past of Otzi and Kennewick Man

In 1991 two hikers stumbled upon a corpse poking out of a melting glacier in the Tyrolean Alps. Thinking that it was the victim of a skiing accident, rescue workers jackhammered the body out of the ice, damaging his thigh and his backpack in the process. Only when an archaeologist spotted a Neolithic copper ax did people realize that the man was five thousand years old.2 Ötzi the Iceman, as he is now called, became a celebrity. He appeared on the cover of Time magazine and has been the subj...

 There is Too Much Art to Consume It All

So I have a counterclaim that exists today - Deviantart. Why can't everyone be an artist? Because you can only consume so much art. I have a page group that is currently ~45 pages of artists on that website whose galleries I need to review and potentially watch. They total up to around 15k works of art, and that pool just grows, I can never get it under wraps, because it would take me probably a full workweek just to get through half of that. On that, I'm already following nearly one thousa...

 Three Types of Artificial Intelligence

Lighthill begins by dividing artificial intelligence into three areas which he calls A, B, and C. A stands for advanced automation, the objective being to replace human beings by machines for specific purposes, for example, industrial assembly, military reconnaissance or scientific analysis. A large body of work in category A is concerned with pattern recognition, with the programming of computers to read documents or to recognize spoken words. C stands for computer-based central-nervous-syst...

 Economic Forecasting VS Science Fiction Predictions

There are two ways to predict the progress of technology. One way is economic forecasting, the other way is science fiction. Economic forecasting makes predictions by extrapolating curves of growth from the past into the future. Science fiction makes a wild guess and leaves the judgment of its plausibility to the reader. Economic forecasting is useful for predicting the future up to about ten years ahead. Beyond ten years it rapidly becomes meaningless. Beyond ten years the quantitative chang...

 The Unspecialized Will Inherit the Earth

Why is it that our whole economic and political system has tended recently to become so sluggish and inflexible? Why have we become resigned to the idea that nothing substantial can ever be done in less than ten years? Obviously there are many reasons. But I believe the principal reason for this sluggishness is that our whole society has fallen into the same trap as our nuclear industry. Not only in the nuclear industry but in many other industries and public institutions, we have pursued eco...

 Matrioshka Brains

Matrioshka Brains (MB)1 are megascale computers constructed out of microelectronic and/or nanoscale components.  MB may be constructed as shells around a star (internally powered Matrioshka Brains: IPMB) or may be constructed independently of a star if large amounts of power are harvested from stars in other locations and beamed to the MB (externally powered Matrioshka Brains: EPMB).  A third variant, (self-powered Matrioshka Brains: SPMB) which generates power via controlled n...

 MarsOne Response to Muslim Fatwa

And among His Signs is the creation of the heavens and the earth, and the variations in your languages and your colors: verily in that are Signs for those who know. (Quran 30: 22) The Muslim world has a rich tradition of exploration. The verse from the Quran above encourages Muslims to go out and see the signs of God’s creation in the ‘heavens and the earth’. The most influential example of this was the Moroccan Muslim traveller, Ibn Battuta, who from 1325 to 1355 travelled 73,000 mile...
