Ord on the precipice that faces us

If all goes well, human history is just beginning. Humanity is about two hundred thousand years old. But the Earth will remain habitable for hundreds of millions more—enough time for millions of future generations; enough to end disease, poverty and injustice forever; enough to create heights of flourishing unimaginable today. And if we could learn to reach out further into the cosmos, we could find more time yet: trillions of years, to explore billions of worlds. Such a lifespan places present-day humanity in its earliest infancy. A vast and extraordinary adulthood awaits.

This book argues that safeguarding humanity’s future is the defining challenge of our time. For we stand at a crucial moment in the history of our species. Fueled by technological progress, our power has grown so great that for the first time in humanity’s long history, we have the capacity to destroy ourselves—severing our entire future and everything we could become.

Yet humanity’s wisdom has grown only falteringly, if at all, and lags dangerously behind. Humanity lacks the maturity, coordination and foresight necessary to avoid making mistakes from which we could never recover. As the gap between our power and wisdom grows, our future is subject to an ever-increasing level of risk. The situation is unsustainable. So over the next few centuries, humanity will be tested: it will either act decisively to protect itself and its longterm potential, or, in all likelihood, this will be lost forever.

To survive these challenges and secure our future, we must act now: managing the risks of today, averting those of tomorrow, and becoming the kind of society that will never pose such risks to itself again.

Working on geoengineering and AI briefings

Last Christmas break, I wrote a detailed briefing on the existential risks to humanity from nuclear weapons.

This year I am starting two more: one on the risks from artificial intelligence, and one on the promises and perils of geoengineering, which I increasingly feel is emerging as our default response to climate change.

I have had a few geoengineering books in my book stacks for years, generally buried under the whaling books in the ‘too depressing to read’ zone. AI I have been learning a lot more about recently, including through Nick Bostrom and Toby Ord’s books and Robert Miles’ incredibly helpful YouTube series (based on Amodei et al’s instructive paper).

While global conditions and humanity’s prospects for the future are disastrous, my own life has become a lot more stable and emotionally tolerable over the course of this past year of employment. The PhD did immense psychological damage to me. After a lifetime in a competitive education system in which I had done exceptionally well, the PhD tended to reinforce the conclusion that everything I did was bad and wrong, and that I had no control over what would happen to my life. I had serious fears about ever finding stable employment after that long and demoralizing time away from the job market (though still always working, to limit the financial damage from those extra years in school). Being out and employed — and even seeing shadows of other possibilities in the future — gives me a sense materially, psychologically, and physiologically of being able to rebuild and endure.

As noted in my pre-US-election post, having a stable home and income makes the disasters around the world seem less like personal catastrophes, though the general population are behaving foolishly when they assume that the 2020–60 period will bear any resemblance to the ‘normality’ of, say, the 1980–2020 period. Of course, there has been no such thing as intergenerational stability or normality since the Industrial Revolution; after centuries where many lives remained broadly similar, the world is now transforming every generation or faster. In the 20th century, much of that change was about technological deployment. In the years ahead, ecological disruption will be a bigger part of the story — along with the technological, sociological, and political convulsions which will accompany the collapse of systems that have supported our civilization for eons.

My own answer to living through a time of catastrophe — in many ways, literally an apocalypse and the end of humanity, as we are all thrown into a post-human future where technology and biology fuse together — is to apply myself in doing my best in everything I undertake, whether that’s photographing a conference, making sandwiches for dinner, or advocating for climate stability and reduced nuclear weapon risks.

None of us can control the world. A huge dark comet could wipe us out tomorrow. A supervolcano or a coronal mass ejection from the sun could abruptly knock us into a nuclear-winter-like world or a world where all our technology gets broken simultaneously, stopping the farm-to-citizens conveyer belt that keeps us alive. There are frighteningly grounded descriptions of how a nuclear war could throw us all into the dark simultaneously, perhaps unable to resume long-distance contact with others for months or years.

It really could happen all of a sudden, with no opportunities for takesies-backsies or improving our resilience after the fact. We live in a world on a precipice, so all we can do is share our gratitude, appreciation, and esteem with those who have enriched our lives while it is possible to do so, while retaining our determination to keep fighting for a better world, despite our species’ manifest inabilities and pathologies.

Worms or moles

It is not hyperbole to make the statement [that] if humans ever reside on the Moon, they will have to live like ants, earthworms or moles. The same is true for all round celestial bodies without a significant atmosphere or magnetic field—Mars included. —Dr. James Logan, Former NASA Chief of Flight Medicine and Chief of Medical Operations at Johnson Space Center.

Mars as a refuge for humanity?

Consider the 2015 Newsweek article: “Star Wars’ Class Wars: Is Mars the Escape Hatch for the 1 Percent?” which claims “the red planet will likely only be for the rich, leaving the poor to suffer as earth’s environment collapses and conflict breaks out.” The only way you could believe this would be if you had no idea how thoroughly, incredibly, impossibly horrible Mars is. The average surface temperature is about -60°C. There’s no breathable air, but there are planetwide dust storms and a layer of toxic dust on the ground. Leaving a 2°C warmer Earth for Mars would be like leaving a messy room so you can live in a toxic waste dump.

The truth is that settling other worlds, in the sense of creating self-sustaining societies somewhere away from Earth, is not only quite unlikely anytime soon, it won’t deliver on the benefits touted by advocates. No vast riches, no new independent nations, no second home for humanity, not even a safety bunker for ultra elites.

Mars is nowhere near being a Plan B home for humanity anytime soon. Consider a worst-case climate scenario. The oceans have swollen ten meters higher, drowning New York City and Boston. Low-lying countries like Belgium and the Netherlands have been swallowed up whole. Heat waves make parts of the Southern Hemisphere uninhabitable as the planet is ravaged by floods, droughts, wildfires, and massive tropical cyclones. More than half of the world’s species die, coral reefs become bleached skeletons, freshwater sources from snowpack melt away or are fouled by rising seas, tropical diseases make their way into formerly temperate climates. Crops fail, people starve, and violence breaks out as over a billion climate refugees beat against the closed gates of the comparatively livable North.

That planet? Eden compared to Mars or the Moon. That Earth still has a breathable atmosphere, a magnetosphere to protect against radiation, and quite possibly still has McDonald’s breakfast. It’s not a world we would like to inhabit, but it is the one world in the solar system where you can run around naked for ten minutes and still be alive at the end.

US security assurances and nuclear weapon proliferation

Although France has historically been the only case of an insurance hedger opting for an independent deterrent, there is no guarantee it will be the last. Under President Trump’s leadership, significant doubts about America’s commitment to both Europe and East Asia led to growing concerns that the United States may not indefinitely remain a reliable and credible provider of extended deterrence—concerns that may remain long after the Trump administration as allies fear abandonment temptations could one day return to the White House. Burden-sharing disputes with NATO, Japan, and South Korea, and efforts to reduce America’s conventional footprint—a key indicator of its commitment to its allies—have led to questions in Germany about whether it requires a substitute to American extended deterrence, and similar discussions at least privately in Japan and South Korea among some domestic constituencies. Doubts about the reliability of America’s commitment to extended deterrence came to a boil under President Trump, who was at times perceived by allies such as South Korea as being willing to throw partners under the bus in pursuit of hisown policy objectives, such as a deal with North Korea’s Kim Jong Un. The experience has the potential to revive debates about independent deterrents in America’s long-time allies—and not just for instrumental reasons to elicit stronger reassurance from Washington to hedge against future incarnations of Trumpism that seeks to retrench America’s commitments back home.

AI image generation and the credibility of photos

When AI-assisted photo manipulation is easy to do and hard to detect, the credibility of photos as evidence is diminished:

No one on Earth today has ever lived in a world where photographs were not the linchpin of social consensus — for as long as any of us has been here, photographs proved something happened. Consider all the ways in which the assumed veracity of a photograph has, previously, validated the truth of your experiences. The preexisting ding in the fender of your rental car. The leak in your ceiling. The arrival of a package. An actual, non-AI-generated cockroach in your takeout. When wildfires encroach upon your residential neighborhood, how do you communicate to friends and acquaintances the thickness of the smoke outside?

For the most part, the average image created by these AI tools will, in and of itself, be pretty harmless — an extra tree in a backdrop, an alligator in a pizzeria, a silly costume interposed over a cat. In aggregate, the deluge upends how we treat the concept of the photo entirely, and that in itself has tremendous repercussions. Consider, for instance, that the last decade has seen extraordinary social upheaval in the United States sparked by grainy videos of police brutality. Where the authorities obscured or concealed reality, these videos told the truth.

Perhaps we will see a backlash against the trend where every camera is also a computer that tweaks the image to ‘improve’ it. For example, there could be cameras that generate a hash from the unedited image and retains it, allowing any subsequent manipulation to be identified.

The nuclear razor’s edge

I listened to the audiobook of Annie Jacobson’s Nuclear War. Having followed the subject and read a lot about it over the years, it nonetheless had a lot of new information inside of a compellingly presented, plausible, and chlling story.

Our whole world can end in a couple of hours; live life accordingly.
