Cultural Change in Technology

As our modern dinosaurs crash down around us, I sometimes wonder what kind of humans will eventually walk out of this epic transformation. Trump and the populism that’s rampaging around the world today, marked by xenophobia, racism, sexism, and rising inequality, is greatly amplified by the forces the GDE has unleashed. For someone like me who saw the power of connection build a vibrant, technologically meshed ecosystem distinguished by peace, love, and understanding, the polarization and hat...

 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...

 Skepticism in Science has Grown

In 1982, polls showed that 44 percent of Americans believed God had created human beings in their present form. Thirty years later, the fraction of the population who are creationists is 46 percent. In 1989, when “climate change” had just entered the public lexicon, 63 percent of Americans understood it was a problem. Almost 25 years later, that proportion is actually a bit lower, at 58 percent. The timeline of these polls defines my career in science. In 1982 I was an undergraduate physics...

 It's Raining DNA Outside

It is raining DNA outside. On the bank of the Oxford canal at the bottom of my garden is a large willow tree, and it is pumping downy seeds into the air. ... [spreading] DNA whose coded characters spell out specific instructions for building willow trees that will shed a new generation of downy seeds. … It is raining instructions out there; it's raining programs; it's raining tree-growing, fluff-spreading, algorithms. That is not a metaphor, it is the plain truth. It couldn't be any plainer i...

 Society Never Escaped the Blandness of Generation X

At the time that the web was born, in the early 1990s, a popular trope was that a new generation of teenagers, reared in the conservative Reagan years, had turned out exceptionally bland. The members of “Generation X” were characterized as blank and inert. The anthropologist Steve Barnett compared them to pattern exhaustion, a phenomena in which a culture runs out of variations of traditional designs in their pottery and becomes less creative. [...] Here is a claim I wish I weren’t making, ...

 The Strong Anthropic Principle

The weak anthropic principle is not very controversial. But there is a stronger form that we will argue for here, although it is regarded with disdain among some physicists. The strong anthropic principle suggests that the fact that we exist imposes constraints not just on our environment but on the possible form and content of the laws of nature themselves. The idea arose because it is not only the peculiar characteristics of our solar system that seem oddly conducive to the development of h...
