My new article for TechCrunch on capitalism and the robot revolution:

Economic experts are trying to figure out a question that just two decades ago seemed ridiculous: If 90 percent of human jobs are replaced by robots in the next 50 years — something now considered plausible — is capitalism still the ideal economic system to champion? No one is certain about the answer, but the question is making everyone nervous — and forcing people to dig deep inside themselves to discover the kind of future they want.

After America beat Russia in the Cold War, most of the world generally considered capitalism to be the hands-down best system on which to base economies and democracies. For decades, few doubted capitalism’s merit, which was made stronger by thriving globalization and a skyrocketing world net worth. In 1989 — when the Berlin Wall fell — the world had only 198 billionaires. Now, according to Forbes, there are 1,826 of them in 2016.

Despite growing riches, when banks collapsed in 2007 during the Great Recession, the world stepped back and wondered aloud if a more nuanced approach to economic progress was needed. These doubts of 21st century capitalism helped set the stage for an economic paradigm shift just starting to appear — economists observing jobs not just disappearing to other countries, but disappearing off the face of the Earth. The culprit: robots and software.

Astronomers have captured video evidence of a collision between Jupiter and a small celestial object, likely a comet or asteroid. Though it looks like a small blip of light, the resulting explosion was unusually powerful.

As Phil Plait of Bad Astronomy reports, the collision occurred on March 17, but confirmation of the event only emerged this week. An amateur Austrian astronomer used a 20-centimeter telescope to chronicle the unexpected event, but it could’ve been some kind of visual artifact.

Synthetic biology involves creating or re-engineering microbes or other organisms to perform specific tasks, like fighting obesity, monitoring chemical threats or creating biofuels. Essentially, biologists program single-celled organisms like bacteria and yeast much the same way one would program and control a robot.

But 10 years ago, it was extremely challenging to take a DNA sequence designed on a computer and turn it into a polymer that could implement its task in a specific host, say a mouse or human cell. Now, thanks to a multitude of innovations across computing, engineering, biology and other fields, researchers can type out any DNA sequence they want, email it to a synthesis company, and receive their completed DNA construct in a week. You can build entire chromosomes and entire genomes of bacteria in this way.

“Biology is the most powerful substrate for engineering that we know of,” said Christopher Voigt, Professor of Biological Engineering at MIT. “It’s more powerful than electrical engineering, mechanical engineering, materials science and others. Unlike all the other fields, we can look at what biology is already able to do. When we look at the natural world, we see things like the brain. That’s a complex place computing, electrical engineering and computer science can’t reach. The brain even constructs nanostructures very deliberately, something materials science has not accomplished.”

A flexible, paper-like ceramic material has been created that promises to provide an inexpensive, fireproof, non-conductive base for a whole range of new and innovative electronic devices (Credit: Eurakite). View gallery (4 images)

Materials to make hard-wearing, bendable non-conducting substrates for wearables and other flexible electronics are essential for the next generation of integrated devices. In this vein, researchers at the University of Twente have reformulated ceramic materials so that they have the flexibility of paper and the lightness of a polymer, but still retain exceptional high-temperature resistance. The new material has been dubbed flexiramics.

High-tech materials such as flexible polymers show promise in this regard, as does boron nitride, and may eventually make the cheaper, but more brittle insulators – such as those made from traditional ceramics – a thing of the past. However, the new ceramic material, named flexiramics, could give these new materials a run for their money as it is not only a tissue-like material that is easy to fold without breaking, it is also reportedly inexpensive and easy to produce.

Today, Lawrence Livermore National Lab (LLNL) and IBM announced the development of a new Scale-up Synaptic Supercomputer (NS16e) that highly integrates 16 TrueNorth Chips in a 4×4 array to deliver 16 million neurons and 256 million synapses. LLNL will also receive an end-to-end software ecosystem that consists of a simulator; a programming language; an integrated programming environment; a library of algorithms as well as applications; firmware; tools for composing neural networks for deep learning; a teaching curriculum; and cloud enablement.

The $1 million computer has 16 IBM microprocessors designed to mimic the way the brain works.

IBM says it will be five to seven years before TrueNorth sees widespread commercial use, but the Lawrence Livermore test is a big step in that direction.
