I know but, Thalidomide, or whatever, that went really haywire, they did a good job, people are scared. They’re not scared of videogames, they’re scared of dangerous pharmaceuticals
Worth noting that the FDA's good job on thalidomide happened before the most recent major round of standards-tightening. Not because of it. That good job is not necessarily much evidence that the FDA since thalidomide is similarly well equipped to do a good job. Which, I think we saw when looking at what passed for "warp speed" in 2020-2021.
My alternate theory on why nuclear energy really stopped, is that it was dystopian or even apocalyptic, because it turned out to be very dual-use. If you build nuclear power-plants, it’s only one step away from building nuclear weapons. And it turned out to be a lot trickier to separate those two things out than it looked.
I think Thiel is wrong on this. Nuclear power plants are as close to dual use as they are in part because they are descended from military reactors designed to produce material for weapons. We created the NRC and effectively banned design improvements before civilian reactor research got all that far. Today we have a lot of improved reactor designs that are much further from dual use, much more resistant to catastrophic failure, much easier to scale to smaller size, and that produce much less waste, but never allowed ourselves to build them. It's now been long enough that almost everyone who was an adult during Three Mile Island, and most who were adults during Chernobyl, has since retired, and so maybe the clear growing need for more baseload clean power will finally be able to overcome the regulatory barriers and restart development and deployment of new nuclear with better, more modern tech.
Being from Germany myself, I think the anti-nuclear movement in Germany that was against nuclear weapons on German soil was also very much against nuclear power plants because they saw the connection. To me that seems one of the reasons why Germany is much more anti-nuclear than other EU countries.
As far as the substance goes, nuclear power plants being dual-use is not the biggest concern. The biggest concern is that uranium enrichment is dual-use. A facility that can enrich uranium enough to be useful for nuclear reactors can also be used to enrich it to be weapon-grade.
When thinking about how to deal with Iran's nuclear program, people thought about making a deal where Iran can have nuclear power plants but no uranium enrichment facilities and gets the enriched uranium from the outside, because the uranium enrichment facilities are the key concern.
Today we have a lot of improved reactor designs that are much further from dual use, much more resistant to catastrophic failure, much easier to scale to smaller size, and that produce much less waste, but never allowed ourselves to build them.
I agree on the resistance to failure and less waste production, but disagree on dual use.
Thorium produces uranium-233 which can be used for nuclear reactions. Unlike uranium 235 based energy reactors, thorium produces more uranium-233 than it consumes in the course of producing energy. With thorium reactors, all energy reactors will be producing weapons grade nuclear material. This may be less efficient than traditional reactors dedicated to making nuclear weapons material, but converting a thorium energy plant from energy to weapons making is more trivial.
And if as you say these new reactors design are more simple and small, the capital costs will be much lower, and since thorium is abundant the operational costs are much lower, so the plants will be more spread out geographically and new nations will get it. Overall the headache to global intelligence agencies is much higher.
I also think beyond these specific objections, the dual-use nature nuclear is "overdetermined". There's an amusing part of the interview where Thiel points out that the history of industrial advancement was moving from energy sources that take up more space to ones that take up less, from wood to coal to oil to nuclear. and now we're moving back to natural gas which takes up more space and solar panels that take up a lot of land. Anyways, the atom fundamentally has a lot of energy in it, . but massive amounts of energy in a small space is easy to turn into large explosions. The thing that makes nuclear attractive is the same thing that makes it dangerous. There's been incredible technical progress in preventing nuclear accidents but preventing nuclear weapons requires geopolitical solutions.
I was thinking more about advanced uranium reactor designs rather than thorium. For example, a lot of SMR designs are sealed, making it harder to access fuel/waste during the lifetime or modify operation. Some are also fast neutron reactors, burners not breeders. That means they contain less total fissile material initially than they otherwise would, and consume a large proportion of what would otherwise be fissile or long lived waste.
Yes, you do have to be concerned about people opening them up and modifying them to breeder reactors - but honestly, I think that "Don't allow sales to people who will do that, and also require monitoring to prevent modification" is enough to deter most of the problems, and for what's left, the difference between being able to do that and being able to figure it out for yourself is not nearly as high a hurdle as it was 50-70 years ago.
[Rogan pivots to talking about aliens for a while, which I have no interest in and do not believe the hypothesis is worth privileging. I point you to (and endorse) the bets on this that many LessWrongers have made of up to $150k against the hypothesis.
This reeks of soldier mindset, instead of just ignoring that part of the transcript, you felt the need to seek validation in your opposing opinion by telling us what to think in an unrelated section. The readers can think for themselves and do not need your help to do so.
So if I got the gist of that correctly, Thiel is increasingly sympathetic to AI doomers, because he doesn't want to get sent to the glue factory by Skynet, but he thinks humanity will succeed in shutting things down, rather than the AIs triumphing.
Fellow Thiel fans may be interested in this post of mine called "X-Risk, Anthropics, & Peter Thiel's Investment Thesis", analyzing Thiel's old essay "The Optimistic Thought Experiment", and trying to figure out how he thinks about the intersection of markets and existential risk.
Quick mod note: This was sort of on the edge of "frontpage" vs "personal blog." I think it's mostly talking about big picture trends, but has some elements of community inside-baseball and time sensitive politics. I decided to frontpage it but wasn't that sure.
This post is a transcript of part of a podcast with Peter Thiel, touching on topics of AI, China, extinction, Effective Altruists, and apocalyptic narratives, published on August 16th 2024.
If you're interested in reading the quotes, just skip straight to them, the introduction is not required reading.
Introduction
Peter Thiel is probably known by most readers, but briefly: he is an venture capitalist, the first outside investor in Facebook, cofounder of Paypal and Palantir, and wrote Zero to One (a book I have found very helpful for thinking about building great companies). He has also been one of the primary proponents of the Great Stagnation hypothesis (along with Tyler Cowen).
More local to the LessWrong scene, Thiel was an early funder of MIRI and a speaker at the first Effective Altruism summit in 2013. He funded Leverage Research for many years, and also a lot of anti-aging research, and the seasteading initiative, and his Thiel Fellowship included a number of people who are around the LessWrong scene. I do not believe he has been active around this scene much in the last ~decade.
He appears rarely to express a lot of positions about society, and I am curious to hear them when he does.
In 2019 I published the transcript of another longform interview of his here with Eric Weinstein. Last week another longform interview with him came out, which I listened to.
I got the sense from listening to it that even though we are in conflict on some issues, conversation with him would be worthwhile and interesting. Then about 3 hours in he started talking more directly about subjects that I think actively about and some conflicts around AI, which I think will be of interest to many here, so I've quoted the relevant parts below.
His interviewer, Joe Rogan is a very successful comedian and podcaster. He's not someone who I would go to for insights about AI. I think of him as standing in for a well-intentioned average person, for better or for worse, although he is a little more knowledgeable and a little more intelligent and a lot more curious than the average person. The average Joe. I believe he is talking in good faith to the person before him, and making points that seem natural to many.
Artificial Intelligence
Discussion focused on the AI race and China, atarting at 2:56:40. The opening monologue by Rogan is skippable.
Why Slow Progress on Nuclear Energy?
On the related topic of apocalyptic narratives, I will include this earlier section of Thiel talking about nukes, from 49:15.
Commentary
Arguments About China
I respect Thiel's epistemic process in the discussion of racing with China. He is someone who I expected is substantially invested in various AI companies doing well (e.g. was a founding investor in OpenAI and also a major investor in DeepMind), yet he honestly tried to give the strongest argument he could against racing with China when the topic was being discussed.
I am interested to see a link to the best paper or research analysis that the western AI policy scene has produced of arguments why China will actually not be competitive in the AI race. Perhaps there are good ones around, but I have some suspicion that the people involved are somehow doing worse at the public discourse on this issue than one of the leading venture capitalists who has been funding tech progress in AI...
Winning the Arguments
Hearing him talk about Effective Altruists brought to mind this paragraph from SlateStarCodex:
I was somewhat pleasantly surprised to learn that one of the people who has been a major investor in AI companies and a major political intellectual influence toward tech and scientific acceleration believes that "the scary, dystopian AI narrative is way more compelling" and of "the Effective Altruist people" says "I think this time around they are winning the arguments".
Winning the arguments is the primary mechanism by which I wish to change the world.
I have no interest in this discussion of aliens and do not believe the hypothesis is worth privileging. I point you to (and endorse) the bets on this that many LessWrongers have made of up to $150k against the hypothesis.
