80,000 Hours Podcast

"A shameless recycling of existing content to drive additional audience engagement on the cheap… or the single best, most valuable, and most insight-dense episode we put out in the entire year, depending on how you want to look at it." — Rob Wiblin

It’s that magical time of year once again — highlightapalooza! Stick around for one top bit from each episode, including:

• How to use the microphone on someone’s mobile phone to figure out what password they’re typing into their laptop
• Why mercilessly driving the New World screwworm to extinction could be the most compassionate thing humanity has ever done
• Why evolutionary psychology doesn’t support a cynical view of human nature but actually explains why so many of us are intensely sensitive to the harms we cause to others
• How superforecasters and domain experts seem to disagree so much about AI risk, but when you zoom in it’s mostly a disagreement about timing
• Why the sceptics are wrong and you will want to use robot nannies to take care of your kids — and also why despite having big worries about the development of AGI, Carl Shulman is strongly against efforts to pause AI research today
• How much of the gender pay gap is due to direct pay discrimination vs other factors
• How cleaner wrasse fish blow the mirror test out of the water
• Why effective altruism may be too big a tent to work well
• How we could best motivate pharma companies to test existing drugs to see if they help cure other diseases — something they currently have no reason to bother with

…as well as 27 other top observations and arguments from the past year of the show.

Check out the full transcript and episode links on the 80,000 Hours website.

Remember that all of these clips come from the 20-minute highlight reels we make for every episode, which are released on our sister feed, 80k After Hours. So if you’re struggling to keep up with our regularly scheduled entertainment, you can still get the best parts of our conversations there.

It has been a hell of a year, and we can only imagine next year is going to be even weirder — but Luisa and Rob will be here to keep you company as Earth hurtles through the galaxy to a fate as yet unknown.

Rich countries seem to find it harder and harder to do anything that creates some losers. People who don’t want houses, offices, power stations, trains, subway stations (or whatever) built in their area can usually find some way to block them, even if the benefits to society outweigh the costs 10 or 100 times over.

The result of this ‘vetocracy’ has been skyrocketing rent in major cities — not to mention exacerbating homelessness, energy poverty, and a host of other social maladies. This has been known for years but precious little progress has been made. When trains, tunnels, or nuclear reactors are occasionally built, they’re comically expensive and slow compared to 50 years ago. And housing construction in the UK and California has barely increased, remaining stuck at less than half what it was in the ’60s and ’70s.

Today’s guest — economist and editor of Works in Progress Sam Bowman — isn’t content to just condemn the Not In My Backyard (NIMBY) mentality behind this stagnation. He wants to actually get a tonne of stuff built, and by that standard the strategy of attacking ‘NIMBYs’ has been an abject failure. They are too politically powerful, and if you try to crush them, sooner or later they crush you.

Links to learn more, highlights, video, and full transcript.

So, as Sam explains, a different strategy is needed, one that acknowledges that opponents of development are often correct that a given project will make them worse off. But the thing is, in the cases we care about, these modest downsides are outweighed by the enormous benefits to others — who will finally have a place to live, be able to get to work, and have the energy to heat their home.

But democracies are majoritarian, so if most existing residents think they’ll be a little worse off if more dwellings are built in their area, it’s no surprise they aren’t getting built. Luckily we already have a simple way to get people to do things they don’t enjoy for the greater good, a strategy that we apply every time someone goes in to work at a job they wouldn’t do for free: compensate them. 

Sam thinks this idea, which he calls “Coasean democracy,” could create a politically sustainable majority in favour of building and underlies the proposals he thinks have the best chance of success — which he discusses in detail with host Rob Wiblin.

"I really don’t want to give the impression that I think it is easy to make predictable, controlled, safe interventions in wild systems where there are many species interacting. I don’t think it’s easy, but I don’t see any reason to think that it’s impossible. And I think we have been making progress. I think there’s every reason to think that if we continue doing research, both at the theoretical level — How do ecosystems work? What sorts of things are likely to have what sorts of indirect effects? — and then also at the practical level — Is this intervention a good idea? — I really think we’re going to come up with plenty of things that would be helpful to plenty of animals." —Cameron Meyer Shorb

In today’s episode, host Luisa Rodriguez speaks to Cameron Meyer Shorb — executive director of the Wild Animal Initiative — about the cutting-edge research on wild animal welfare.

Links to learn more, highlights, and full transcript.

They cover:

• How it’s almost impossible to comprehend the sheer number of wild animals on Earth — and why that makes their potential suffering so important to consider.
• How bad experiences like disease, parasites, and predation truly are for wild animals — and how we would even begin to study that empirically.
• The tricky ethical dilemmas in trying to help wild animals without unintended consequences for ecosystems or other potentially sentient beings.
• Potentially promising interventions to help wild animals — like selective reforestation, vaccines, fire management, and gene drives.
• Why Cameron thinks the best approach to improving wild animal welfare is to first build a dedicated research field — and how Wild Animal Initiative’s activities support this.
• The many career paths in science, policy, and technology that could contribute to improving wild animal welfare.
• And much more.

One OpenAI critic calls it “the theft of at least the millennium and quite possibly all of human history.” Are they right?

Back in 2015 OpenAI was but a humble nonprofit. That nonprofit started a for-profit, OpenAI LLC, but made sure to retain ownership and control. But that for-profit, having become a tech giant with vast staffing and investment, has grown tired of its shackles and wants to change the deal.

Facing off against it stand eight out-gunned and out-numbered part-time volunteers. Can they hope to defend the nonprofit’s interests against the overwhelming profit motives arrayed against them?

That’s the question host Rob Wiblin puts to nonprofit legal expert Rose Chan Loui of UCLA, who concludes that with a “heroic effort” and a little help from some friendly state attorneys general, they might just stand a chance.

Links to learn more, highlights, video, and full transcript.

As Rose lays out, on paper OpenAI is controlled by a nonprofit board that:

• Can fire the CEO.
• Would receive all the profits after the point OpenAI makes 100x returns on investment.
• Is legally bound to do whatever it can to pursue its charitable purpose: “to build artificial general intelligence that benefits humanity.”

But that control is a problem for OpenAI the for-profit and its CEO Sam Altman — all the more so after the board concluded back in November 2023 that it couldn’t trust Altman and attempted to fire him (although those board members were ultimately ousted themselves after failing to adequately explain their rationale).

Nonprofit control makes it harder to attract investors, who don’t want a board stepping in just because they think what the company is doing is bad for humanity. And OpenAI the business is thirsty for as many investors as possible, because it wants to beat competitors and train the first truly general AI — able to do every job humans currently do — which is expected to cost hundreds of billions of dollars.

So, Rose explains, they plan to buy the nonprofit out. In exchange for giving up its windfall profits and the ability to fire the CEO or direct the company’s actions, the board will become minority shareholders with reduced voting rights, and presumably transform into a normal grantmaking foundation instead.

Is this a massive bait-and-switch? A case of the tail not only wagging the dog, but grabbing a scalpel and neutering it?

OpenAI repeatedly committed to California, Delaware, the US federal government, founding staff, and the general public that its resources would be used for its charitable mission and it could be trusted because of nonprofit control. Meanwhile, the divergence in interests couldn’t be more stark: every dollar the for-profit keeps from its nonprofit parent is another dollar it could invest in AGI and ultimately return to investors and staff.

• Is this a unique case? (00:27:24)
• Is control of OpenAI 'priceless' to the nonprofit in pursuit of its mission? (00:28:58)
• The crazy difficulty of valuing the profits OpenAI might make (00:35:21)
• Control of OpenAI is independently incredibly valuable and requires compensation (00:41:22)

"I think stories are the way we shift the Overton window — so widen the range of things that are acceptable for policy and palatable to the public. Almost by definition, a lot of things that are going to be really important and shape the future are not in the Overton window, because they sound weird and off-putting and very futuristic. But I think stories are the best way to bring them in." — Elizabeth Cox

"I think one of the reasons I took [shutting down my charity] so hard is because entrepreneurship is all about this bets-based mindset. So you say, “I’m going to take a bunch of bets. I’m going to take some risky bets that have really high upside.” And this is a winning strategy in life, but maybe it’s not a winning strategy for any given hand. So the fact of the matter is that I believe that intellectually, but l do not believe that emotionally. And I have now met a bunch of people who are really good at doing that emotionally, and I’ve realised I’m just not one of those people. I think I’m more entrepreneurial than your average person; I don’t think I’m the maximally entrepreneurial person. And I also think it’s just human nature to not like failing." —Sarah Eustis-Guthrie

In today’s episode, host Luisa Rodriguez speaks to Sarah Eustis-Guthrie — cofounder of the now-shut-down Maternal Health Initiative, a postpartum family planning nonprofit in Ghana — about her experience starting and running MHI, and ultimately making the difficult decision to shut down when the programme wasn’t as impactful as they expected.

• Early yellow and red flags that maybe they didn’t have the full story about the effectiveness of the intervention.
• All the steps Sarah and Ben took to build the organisation — and where things went wrong in retrospect.
• Dealing with the emotional side of putting so much time and effort into a project that ultimately failed.
• Why it’s so important to talk openly about things that don’t work out, and Sarah’s key lessons learned from the experience.

"In that famous example of the dress, half of the people in the world saw [blue and black], half saw [white and gold]. It turns out there’s individual differences in how brains take into account ambient light. Colour is one example where it’s pretty clear that what we experience is a kind of inference: it’s the brain’s best guess about what’s going on in some way out there in the world. And that’s the claim that I’ve taken on board as a general hypothesis for consciousness: that all our perceptual experiences are inferences about something we don’t and cannot have direct access to." —Anil Seth

In today’s episode, host Luisa Rodriguez speaks to Anil Seth — director of the Sussex Centre for Consciousness Science — about how much we can learn about consciousness by studying the brain.

2. How much better some candidates are for the world as a whole, compared to others.

He then discusses a couple of the best arguments against voting in important elections, namely:

1. If an election is competitive, that means other people disagree about which option is better, and you’re at some risk of voting for the worse candidate by mistake.
2. While voting itself doesn’t take long, knowing enough to accurately pick which candidate is better for the world actually does take substantial effort — effort that could be better allocated elsewhere.

Finally, Rob covers the impact of donating to campaigns or working to "get out the vote," which can be effective ways to generate additional votes for your preferred candidate.

We last released this article in October 2020, but we think it largely still stands up today.

"You have a tank split in two parts: if the fish gets in the compartment with a red circle, it will receive food, and food will be delivered in the other tank as well. If the fish takes the blue triangle, this fish will receive food, but nothing will be delivered in the other tank. So we have a prosocial choice and antisocial choice. When there is no one in the other part of the tank, the male is choosing randomly. If there is a male, a possible rival: antisocial — almost 100% of the time. Now, if there is his wife — his female, this is a prosocial choice all the time.

"And now a question: Is it just because this is a female or is it just for their female? Well, when they're bringing a new female, it’s the antisocial choice all the time. Now, if there is not the female of the male, it will depend on how long he's been separated from his female. At first it will be antisocial, and after a while he will start to switch to prosocial choices." —Sébastien Moro

In today’s episode, host Luisa Rodriguez speaks to science writer and video blogger Sébastien Moro about the latest research on fish consciousness, intelligence, and potential sentience.

They cover:

• The insane capabilities of fish in tests of memory, learning, and problem-solving.
• Examples of fish that can beat primates on cognitive tests and recognise individual human faces.
• Fishes’ social lives, including pair bonding, “personalities,” cooperation, and cultural transmission.
• Whether fish can experience emotions, and how this is even studied.
• The wild evolutionary innovations of fish, who adapted to thrive in diverse environments from mangroves to the deep sea.
• How some fish have sensory capabilities we can’t even really fathom — like “seeing” electrical fields and colours we can’t perceive.
• Ethical issues raised by evidence that fish may be conscious and experience suffering.
• And plenty more.
