August 2018 in Review

Most frightening stories:

  • In certain provinces with insurgent activity, the Chinese government is reportedly combining surveillance and social media technologies to score people and send those with low scores to re-education camps, from which it is unclear if anyone returns.
  • Noam Chomsky doesn’t love Trump, but points out that climate change and/or nuclear weapons are still existential threats and that more mainstream leaders and media outlets have failed just as miserably to address them as Trump has. In related news, the climate may be headed for a catastrophic tipping point and while attention is mostly elsewhere, a fundamentalist takeover of Pakistan’s nuclear arsenal is still one of the more serious risks out there.
  • The U.S. government is apparently very worried about a severe cyber attack. Also, a talented 11-year-old can hack a voting machine.

Most interesting stories, that were not particularly frightening or hopeful, or perhaps were a mixture of both:

body scanners from Total Recall are now a thing

The Los Angeles subway is installing the body scanners from Total Recall (the good 1990 version, not the garbage 2012 remake.)

The machines scan for metallic and non-metallic objects on a person’s body, can detect suspicious items from 30 feet (9 meters) away and have the capability of scanning more than 2,000 passengers per hour…

In addition to the Thruvision scanners, the agency is also planning to purchase other body scanners — which resemble white television cameras on tripods — that have the ability to move around and hone in on specific people and angles, Wiggins said.

July 2018 in Review

Most frightening stories:

  • The UN is warning as many as 10 million people in Yemen could face starvation by the end of 2018 due to the military action by Saudi Arabia and the U.S. The U.S. military is involved in combat in at least 8 African countries. And Trump apparently wants to invade Venezuela.
  • The Trump administration is attacking regulations that protect Americans from air pollution and that help ensure our fisheries are sustainable. Earth Overshoot Day is on August 1 this year, two days earlier than last year.
  • The U.S. has not managed a full year of 3% GDP growth since 2005, due to slowing growth and the working age population and slowing productivity growth, and these trends seem likely to continue even if the current dumb policies that make them worse were to be reversed. Some economists think a U.S. withdrawal from the World Trade Organization could trigger a recession (others do not).

Most hopeful stories:

  • Looking at basic economic and health data over about a 50-200 time frame reminds us that enormous progress has been made, even though the last 20 years or so seems like a reversal.
  • Simultaneous Policy is an idea where multiple legislatures around the world agree to a single policy on a fairly narrow issue (like climate change or arms reductions).
  • I was heartened by the compassion Americans showed for children trapped in a cave 10,000 miles away. The news coverage did a lot to humanize these children, and it would be nice to see more of that closer to home.

more on cosmogenesis in science fiction

I figured there must be a lot of science fiction about scientists creating universes. In 15 minutes of searching I only came up with two that I didn’t know about:

The Last Question by Isaac Asimov (1956) – In this one, people and computers are trying to figure out over many generations what to do when the universe ends. I won’t spoil the ending.

Schild’s Ladder by Greg Eagen (2002) – I think this one is about a universe accidentally created by scientists. There is a plot summary on Wikipedia but I didn’t want to read it and spoil it for myself.

cosmogenesis

Here’s a fascinating article about the possibility of creating a new universe in a laboratory (or many of them). This is not about virtual reality or artificial intelligence, this is about creating a wormhole to an actual new physical baby universe. A number of physicists think it is theoretically possible and take it seriously. This has any number of mind-bending implications. First, our own universe could have come about this way, whether created by a deity as some of us imagine or by some intelligent but fallible mortal being out there. Second, and the article goes into this, the creator of such a universe might be able to observe it but would have no control over it (although at least in theory, they might be able to actually travel to it.) Third, and the article doesn’t mention this, let’s say humanity somehow manages to survive the billions or trillions of years it would take for our own universe to run its course and begin to collapse (assuming that is going to happen), maybe this creates the possibility that our species could exist forever. Well, we have a lot of things to figure out between now and then obviously. One final thing I learned from this article is that physicists also have a theory of how our universe could have arisen completely spontaneously from nothing at all and without intervention by any external intelligent being. Even that has implications – if it could happen once, does it just continue to happen every now and then somewhere in space and time? The interesting implication there could be that intelligent life has always existed somewhere out there and always will.

There is science fiction about this of course. Starmaker by Olaf Stapledon comes to mind, and of course The Matrix. And of course, Lisa Simpson. There must be others.

test tube dog food

It makes sense that dog food would be the first serious commercial application of synthetic meat.

I can’t help thinking of the yeast vats in Isaac Asimov’s 1953 Caves of Steel. That idea has almost literally come true.

Bethencourt compares his company’s production of “clean” protein to that of sake—imagine giant fermentation tanks—right down to using the same ingredient to fuel its protein growth. Koji, a fungus, is the Japanese version of baker’s yeast. It grows rapidly inside tanks, along with sugar and nutrients, at the right balmy temperature. The result is a plant-based protein with a close match to eggs or animal-based meat. Because koji is widely consumed by humans, it already has a GRAS (Generally Recognized As Safe) designation. Wild Earth’s supply chain is simple—it uses only a handful of ingredients—and easily traceable.

brain uploading

Good news – instead of killing you, slicing up your brain, freezing it and keeping it on ice so they can revive your consciousness centuries in the future, scientists might now be able to scan your brain and just store the pattern for later use. The bad news – they still have to kill you, slice up your brain, and freeze it first before they do the scanning. And of course there is still the old Star Trek transporter problem – when they save your pattern, disintegrate your matter, and recreate the pattern somewhere else using new matter, is it really still the same you, or is it a different you with the same memories as the original you? The new you won’t know the difference, and you won’t know the difference either because you won’t exist, so does it matter? Well, the technology still has a ways to go before we really have to worry about any of this. If they can ever find a way to save a detailed copy of your brain without killing you first, there would be very little downside to trying it. And before you ask, yes, I have read the book Altered Carbon, and no, I have not seen the new show Altered Carbon.

A Deepness in the Sky

I just finished A Deepness in the Sky by Vernor Vinge, and it was the most enjoyable book I have read in the last couple years. I’m not going to spoil the plot, but like all Vernor Vinge books it has layers upon layers with themes such as civilizations rising and falling, technological progress (and sometimes regression) with its opportunities and dangers, interactions between civilizations at different levels of technology, and at similar levels of technology but with different cultures and values. The plot unfolds over long periods of time while the characters are very real, accessible, and human, even if not all of them are actually human.

2017 in Review

Most frightening stories of 2017:

  • January: The U.S. government may be “planning to roll back or dilute many of the provisions of Dodd-Frank, particularly those that protect consumers from toxic financial products and those that impose restrictions on banks”.
  • February: The Doomsday Clock was moved to 2.5 minutes to midnight. The worst it has ever been was 2 minutes to midnight in the early 1980s. In related news, the idea of a U.S.-China war is looking a bit more plausible. The U.S. military may be considering sending ground troops to Syria.
  • MarchLa Paz, Bolivia, is in a serious crisis caused by loss of its glacier-fed water supply. At the same time we are losing glaciers and snowpack in important food-growing regions, the global groundwater situation is also looking bleak. And for those of us trying to do our little part for water conservation, investing in a residential graywater system can take around 15 years to break even at current costs and water rates.
  • April: The U.S. health care market is screwed up seemingly beyond repair. Why can’t we have nice things? Oh right, because our politicians represent big business, not voters. Also, we have forgotten the difference between a dialog and an argument.
  • May: We hit 410 ppm at Mauna Loa.
  • JuneThe Onion shared this uncharacteristically unfunny observation: “MYTH: There is nothing mankind can do to prevent climate change. FACT: There is nothing mankind will do to prevent climate change”. It’s not funny because it’s probably true.
  • July: Long term food security in Asia could be a problem.
  • August: The U.S. construction industry has had negligible productivity gains in the past 40 years.
  • September: During the Vietnam War the United States dropped approximately twice as many tons of bombs in Southeast Asia as the Allied forces combined used against both Germany and Japan in World War II. After the Cold War finally ended, Mikhail Gorbachev made some good suggestions for how to achieve a lasting peace. They were ignored. We may be witnessing the decline of the American Empire as a result.
  • October: It is possible that a catastrophic loss of insects is occurring and that it may lead to ecological collapse. Also, there is new evidence that pollution is harming human health and even the global economy more than previously thought.
  • November: I thought about war and peace in November. Well, mostly war. War is frightening. The United States of America appears to be flailing about militarily all over the world guided by no foreign policy. Big wars of the past have sometimes been started by overconfident leaders thinking they could get a quick military victory, only to find themselves bogged down in something much larger and more intractable than they imagined. But enemies are good to have – the Nazis understood that a scared population will believe what you tell them.
  • December: A lot of people would probably agree that the United States government is becoming increasingly dysfunctional, but I don’t think many would question the long-term stability of our form of government itself. Maybe we should start to do that. The Consumer Financial Protection Bureau has been doing a decent job of protecting consumers and reducing the risk of another financial crisis. The person in charge of it now was put there specifically to ruin it. Something similar may be about to happen at the Census Bureau. A U.S. Constitutional Convention is actually a possibility, and might threaten the stability of the nation.

Most hopeful stories of 2017:

Most interesting stories that weren’t particularly frightening or hopeful, or perhaps were a mixture of both:

  • January: Apple, Google, and Facebook may destroy the telecom industry.
  • February: The idea of growing human organs inside a pig, or even a viable human-pig hybrid, is getting very closeTiny brains can also be grown on a microchip. Bringing back extinct animals is also getting very close.
  • March: Bill Gates has proposed a “robot tax”. The basic idea is that if and when automation starts to increase productivity, you could tax the increase in profits and use the money to help any workers displaced by the automation. In related somewhat boring economic news, there are a variety of theories as to why a raise in the minimum wage does not appear to cause unemployment as classical economic theory would predict.
  • April: I finished reading Rainbow’s End, a fantastic Vernor Vinge novel about augmented reality in the near future, among other things.
  • May: The sex robots are here.
  • June: “Fleur de lawn” is a mix of perennial rye, hard fescue, micro clover, yarrow, Achillea millefolium, sweet alyssum, Lobularia maritima, baby blue eyes, Nemophila menziesi, English daisy, Bellis perennis, and O’Connor’s strawberry clover, Trifolium fragiferum.
  • July: Ecologists have some new ideas for measuring resilience of ecosystems. Technologists have some wild ideas to have robots directly counteract the effects of humans on ecosystems. I like ideas – how do I get a (well-compensated) job where I can just sit around and think up ideas?
  • August: Elon Musk has thrown his energy into deep tunneling technology.
  • September: I learned that the OECD Science, Technology and Innovation Outlook named “ten key emerging technology trends”: The Internet of Things, Big data analytics, Artificial intelligence, Neurotechnologies, Nano/microsatellites, Nanomaterials, Additive manufacturing / 3D printing, Advanced energy storage technologies, Synthetic biology, Blockchain
  • October: Even if autonomous trucks are not ready for tricky urban situations, they could be autonomous on the highway with a small number of remote-control drivers guiding a large number of tricks through tricky urban maneuvers, not unlike the way ports or trainyards are run now. There is also new thinking on how to transition highways gradually through a mix of human and computer-controlled vehicles, and eventually to full computer control. New research shows that even a small number of autonomous vehicles mixed in with human drivers will be safer for everyone. While some reports predict autonomous taxis will be available in the 2020s, Google says that number is more like 2017.
  • November: It’s possible that the kind of ideal planned economy envisioned by early Soviet economists (which never came to pass) could be realized with the computing power and algorithms just beginning to be available now.
  • DecemberMicrosoft is trying to one-up Google Scholar, which is good for researchers. More computing firepower is being focused on making sense of all the scientific papers out there.

I’ll keep this on the short side. Here are a few trends I see:

Risk of War. I think I said about a year ago that if we could through the next four years without a world war or nuclear detonation, we will be doing well. Well, one year down and three to go. That’s the bright side. The dark side is that it is time to acknowledge there is a regional war going on in the Middle East. It could escalate, it could go nuclear, and it could result in military confrontation between the United States and Russia. Likewise, the situation in North Korea could turn into a regional conflict, could go nuclear, and could lead to military confrontation between the United States and China.

Decline…and Fall? A question on my mind is whether the United States is a nation in decline, and I think the surprisingly obvious answer is yes. The more important question is whether it is a temporary dip, or the beginning of a decline and fall.

Risk of Financial Crisis. The risk of another serious financial crisis is even scarier that war in some ways, at least a limited, non-nuclear war. Surprisingly, the economic effects can be more severe, more widespread and longer lasting. We are seeing the continued weakening of regulations attempting to limit systemic risk-taking for short-term gain. Without a pickup in long-term productivity growth and with the demographic and ecological headwinds that we face, another crisis equal to or worse than the 2007 one could be the one that we don’t recover from.

Ecological Collapse? The story about vanishing insects was eye-opening to me. Could global ecosystems go into a freefall? Could populous regions of the world face a catastrophic food shortage? It is hard to imagine these things coming to a head in the near term, but the world needs to take these risks seriously since the consequences would be so great.

Technology. With everything else going on, technology just marches forward, of course. One technology I find particularly interesting is new approaches to research that mine and attempt to synthesize large bodies of scientific research.

Can the human species implement good ideas? Solutions exist. I would love to end on a positive note, but at the moment I find myself questioning whether our particular species of hairless ape can implement them.

But – how’s this for ending on a positive note – like I said at the beginning, the one thing about 2017 that definitely didn’t suck was that we didn’t get blown up!

liquid metal

The “liquid metal” from Terminator 2 is finally here, although it is not trying to kill us (yet). Still, if they start making autonomous drones out of this stuff…

“If you look at conventional aircraft technology, you have so many moving parts,” says Othmane Benafan, an engineer at NASA’s Glenn Research Center. Those moving parts are essential—they are how pilots steer, reduce turbulence, take off, land, and basically do everything else besides glide aimlessly. But the actuators, cables, motors, lubricant, hydraulic gear, and other bits needed move those parts around take up weight and space—precious resources on any aircraft.

The alternative is to move those wing parts using shapeshifting metals. Or, as they’re known to engineers, shape memory alloys. “Parts made from shape memory alloys are typically 10 to 20 percent the size and weight of a conventional part,” says Jim Mabe, a shape memory alloy guru at Boeing. For an industry that spent $133 billion on fuel last year, anything smaller and lighter is exciting news.

Shape memory alloys are essentially reversible Shrinky Dinks. When heated to certain temperatures, they shrink, twist, and bend. Cool them off, and they return to their original shape. Hot, cold, hot—shape memory alloys can cycle back and forth millions of times without wearing out. All you need is the ability to generate heat or pull it from some other, already spicy hot part of the plane, like the engine.
