December 2020 in Review

2020 is officially in the books!

Most frightening and/or depressing story: The “Map of Doom” identifies risks that should get the most attention, including antibiotic resistance, synthetic biology (also see below), and some complex of climate change/ecosystem collapse/food supply issues.

Most hopeful story: The Covid-19 vaccines are a modern “moonshot” – a massive government investment driving scientific and technological progress on a particular issue in a short time frame. Only unlike nuclear weapons and the actual original moonshot, this one is not military in nature. (We should be concerned about biological weapons, but let’s allow ourselves to enjoy this victory and take a quick trip to Disney Land before we start practicing for next season…) What should be our next moonshot, maybe fusion power?

Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both: Lists of some key technologies that came to the fore in 2020 include (you guessed it) mRNA vaccines, genetically modified crops, a variety of new computer chips and machine learning algorithms, which seem to go hand in hand (and we are hearing more about “machine learning” than “artificial intelligence” these days), brain-computer interfaces, private rockets and moon landings and missions to Mars and mysterious signals and micro-satellites and UFOs, virtual and mixed reality, social media disinformation and work-from-home technologies. The wave of self-driving car hype seems to have peaked and receded, which probably means self-driving cars will probably arrive quietly in the next decade or so. I was surprised not to see cheap renewable energy on any lists that I came across, and I think it belongs there. At least one economist thinks we are on the cusp of a big technology-driven productivity pickup that has been gestating for a few decades.

Ford signals self-driving car’s “intent”

Ford is trying a set of blinking lights to help pedestrians understand whether a self-driving car is likely to stop or run them over. Somewhat interesting, but really I think the legal responsibility needs to be on the car’s owner/programmer and not the pedestrian. If this saves a few lives by preventing a few otherwise unavoidable crashes it is a good thing. If it creates an excuse to blame the victim, it is a bad thing. In recent U.S. history at least, the situation between driver and pedestrian has almost always been the latter.

A back-and-forth white light means the car is yielding. When the car is about to go, the white light quickly blinks. Ford said it’s trying to find a way to communicate that doesn’t use text.

Once cars are machine-driven, any pedestrian-driver communication gets a lot harder. So how does a woman walking or a kid biking check in with a car to know it’s safe to cross the street?

March 2018 in Review

Most hopeful stories:

  • One large sprawling city could be roughly the economic equivalent of several small high-density cities. This could potentially be good news for the planet if you choose in favor of the latter, and preserve the spaces in between as some combination of natural land and farm land.
  • The problems with free parking, and solutions to the problems, are well known. This could potentially be good news if anything were to be actually done about it. Self-parking cars could be really fantastic for cities.
  • The coal industry continues to collapse, and even the other fossil fuels are saying they are a bunch of whining losers. And yes, I consider this positive. I hope there aren’t too many old ladies whose pensions depend on coal at this point.

self-parking cars

Wired explains why cars that can park themselves are going to be so awesome, whether or not they are allowed to cruise the public streets and highways just yet.

Parking is a problem that engineers reckon self-driving cars can solve. Send the robot to find a space, after it drops you off at your destination. Summon it back later when you’re ready to leave.

The fatal accident in Arizona this week, in which an Uber autonomous test vehicle killed a pedestrian pushing a bike across the street, highlights some of the dangers of robo-driving at regular speeds. But low-speed movement, with scanners running on full, in a fixed area, is a much safer way to apply the tech. Building owners could have high resolution maps made of their parking lots, geo-fence them, and designate them as no-human zones, so cars can do their thing. It’ll be just like dropping your car at a valet stand, except you don’t have to dig around for singles. More cars will fit into each lot: Because doors don’t need to be opened, the vehicles can squeeze tightly together.

Being a tech magazine and not an urban planning magazine, they don’t realize the significance of the short phrase “More cars will fit into each lot”. Because most cars are parked most of the time, and they take up such enormous amounts of space, this could fundamentally change the land use in cities over time by opening up enormous amounts of space to other uses. And that is assuming people own the same number of cars they do now. As the incentive to own a private vehicle decreases, more of the fleet will be in motion at any given time and less will be parked, accelerating the virtuous cycle of reduced car demand even more. What kind of uses could be better than parking? Well, any – such as housing, commercial space, parks (the kind with soil and plants), natural areas, solar panels. Now might be a good time for cities and suburbs to start thinking about what they want to do with all this public real estate other than just letting it sit there generating heat, stormwater and pollution. As a start, installing separated bike lanes might not seem such a daunting problem, and just opening up some existing parking as temporary loading zones for deliveries, contractors, the elderly and disabled would be an enormous help in many cities.

humans as a check on self-driving cars?

This article describes the safety protocols Uber had in place to try to avoid a pedestrian death like the one that just happened in Arizona.

Trainees spend time in a classroom reviewing the technology and the testing protocols, and on the track learning to spot and avoid trouble. They even get a day at a racetrack, practicing emergency maneuvers at highway speeds. They’re taught to keep their hands an inch or two from the steering wheel, and the right foot over the brake. If they simply have to look at their phones, they’re supposed to take control of the car and put it in park first.

Working alone in eight-hour shifts (in Phoenix they earn about $24 an hour), the babysitters are then set loose into the wild. Each day, they get a briefing from an engineer: Here’s where you’ll be driving, here’s what to look for. Maybe this version of the software is acting a bit funky around cyclists, or taking one particular turn a little fast.

And constantly, they are told: Watch the road. Don’t look at your phone. If you’re tired, stop driving. Uber also audits vehicle logs for traffic violations, and it has a full-time employee who does nothing but investigate potential infractions of the rules. Uber has fired drivers caught (by other operators or by people on the street) looking at their phones.

fatal automated vehicle crash in Arizona

A Google automated vehicle has killed a pedestrian in Arizona, which has some of the loosest regulations on testing them. I learned about this from the Bicycle Coalition of Philadelphia.

This is certainly a tragedy. The Bicycle Coalition seems to condemn Google for testing the car, then goes on to make the point that human drivers kill people every day, every one is a tragedy, and there isn’t much public outcry about it. I agree with this, and yet I find it interesting that logic and our gut feeling about the morality of the situation seem to be so different. Imagine that changing all cars to self-driving ones would cut the number of people killed by 50% (and I have seen estimates of much larger reductions than that). It would seem immoral not to make that change. But at the same time, it would seem immoral to unleash a fleet of robot cars, knowing that a certain fraction of them are going to kill people, and by killing a few people learn how to not kill as many people in the future. I don’t know the answer to this, except that the technology will gradually get better, and insurance companies may eventually decide the human drivers are not worth the risk.

January 2018 in Review

Most frightening stories:

  • Larry Summers says we have a better than even chance of recession in the next three years. Sounds bad, but I wonder what that stat would look like for any randomly chosen three year period in modern history.
  • The United States is involved in at least seven wars: Afghanistan, Iraq, Syria, Yemen, Libya, Somalia, and Pakistan. Nuclear deterrence may not actually the work.
  • Cape Town, South Africa is in imminent danger of running out of water. Longer term, there are serious concerns about snowpack-dependent water supplies serving large urban populations in Asia and western North America.
