I signed and strongly support this open letter.

Let me add a little global perspective (as a US citizen who's lived in 4 countries outside the US for a total of 14 years, and who doesn't always see the US as the 'good guy' in geopolitics).

The US is 4% of the world's population. The American AI industry is (probably) years ahead of any other country, and is pushing ahead with the rationale that 'if we don't keep pushing ahead, a bad actor (which usually implies China) will catch up, and that would be bad'. Thus, we impose AI X-risk on the other 96% of humans without the informed consent, support, or oversight. 

We used the same arms-race rationale in the 1940s to develop the atomic bomb ('if we don't do it, Germany will') and in the 1950s to develop the hydrogen bomb ('if we don't do it, the Soviet Union will'). In both cases, we were the bad actor. The other countries were nowhere close to us. We exaggerated the threat that they would catch up, and we got the American public to buy into that narrative. But we were really the ones pushing ahead into X-risk territory. Now we're promoting the same narrative for AI development. 'The AI arms race cannot be stopped', 'AGI is inevitable', 'the genie is out of the bottle', 'if not us, then China', etc, etc.

We Americans have a very hard time accepting that 'we might be the baddies'. We are uncomfortable acknowledging any moral obligations to the rest of humanity (if they conflict in any way with our geopolitical interests). We like to impose our values on the world, but we don't like to submit to any global oversight by others. 

I hope that this public discussion about AI risks also includes some soul-searching by Americans -- not just the AI industry, but all of us, concerning the way that our country is, yet again, pushing ahead with developing extremely dangerous technology, without any sense of moral obligation to others.

Having taught online courses for CUHK-Shenzhen in China for a year, and discussed quite a bit about EA, AI, and X risk with the very bright young students there, I often imagine how they would view the recent developments in the American AI industry. I think they would be appalled by our American hubris. They know that the American political system is too partisan, fractured, slow, and dysfunctional to impose any effective regulation on Big Tech. They know that American tech companies are legally obligated (by 'fiduciary duty' to shareholders) to prioritize quarterly profits over long-term human survival. They know that many Bay Area tech bros supporting AI are transhumanists, extropians, or Singularity-welcomers who look forward to humanity being replaced by machines. They know that many Americans view China as a reckless, irresponsible, totalitarian state that isn't worth listening to about any AI safety concerns. So, I imagine, any young Chinese students who's paying attention would take an extremely negative view of the risks that the American AI industry is imposing on the other 7.7 billion people in the world.

Some people have criticised the timing. I think there's some validity to this, but the trigger has been pulled and cannot be unpulled. You might say that we could try write another similar letter a bit further down the track, but it's hard to get people to do the same thing twice and even harder to get people to pay attention.

So I guess we really have the choice to get behind this or not. I think we should get behind this as I see this letter as really opening up the Overton Window. I think it would be a mistake to wait for a theoretical perfectly timed letter to sign, as opposed to signing what we have in front of us.

I sympathise with others who have particular concerns about the details of this letter, and most especially the fact that signatures were unverified (though the link now includes an email validation at the bottom). A good discussion from a sceptical perspective can be found in this thread by Matthew Barnett. However, I think on balance I support FLI releasing this letter, mostly for reasons that Nate states here. I think that if you're pessimistic about the current direction of AI research, and the balance between capabilities/safety, then one of the major actors who would have the ability to step in and co-ordinate those in a race and buy more time would be the U.S. Government. 

Again, I sympathise with scepticism about Government intentions/track record/capability to regulate but I think I'm a lot more sympathetic to it than the LessWrong commenters. That might be a US/UK cultural difference, but I don't think the counterfactual of no public letter and no government action leads to anywhere good, and I simply don't share the same worldview of Neo-Realism in International Relations and Public Choice in Domestic Politics that makes any move in that direction appear to be net-negative ¯\_(ツ)_/¯

Finally, I hope that this letter can serve as a push for AI Governance to be viewed as something that goes hand-in-hand with Technical AI Safety Research. I think that both are very important parts of making this century go well, and I think that the letter is a directional step that we can get behind and improve upon, rather than dismiss.

The Forbes article “Elon Musk's AI History May Be Behind His Call To Pause Development” discusses some interesting OpenAI history and an explanation for how this FLI open letter may have come to be.

(Note: I don’t believe this is the only explanation, or even the most likely one; if pushed I’d assign it maybe 20%, though with large uncertainty bars, of the counterfactual force behind the FLI letter coming into existence. Note also: I’ve signed the letter, I think it’s net positive.)

Some excerpts:

OpenAI was founded as a nonprofit in 2015, with Elon Musk as the public face of the organization. [...] OpenAI was co-founded by Sam Altman, who butted heads with Musk in 2018 when Musk decided he wasn’t happy with OpenAI’s progress. [...] Musk worried that OpenAI was running behind Google and reportedly told Altman he wanted to take over the company to accelerate development. But Altman and the board at OpenAI rejected the idea that Musk—already the head of Tesla, The Boring Company and SpaceX—would have control of yet another company.

“Musk, in turn, walked away from the company—and reneged on a massive planned donation. The fallout from that conflict, culminating in the announcement of Musk’s departure on Feb 20, 2018, [...],” Semafor reported last week.

…

When Musk left his stated reason was that AI technology being developed at Tesla created a conflict of interest. [...] And while the real reason Musk left OpenAI likely had more to do with the power struggle reported by Semafor, there’s almost certainly some truth to the fact that Tesla is working on powerful AI tech.

…

The fact that Musk is so far behind in the AI race needs to be kept in mind when you see him warn that this technology is untested. Musk has had no problem with deploying beta software in Tesla cars that essentially make everyone on the road a beta tester, whether they’ve signed up for it or not.

…

Rather than issuing a statement solely under his own name, it seems like Musk has tried to launder his concern about OpenAI through a nonprofit called the Future of Life Institute. But as Reuters points out, the Future of Life Institute is primarily funded by the Musk Foundation.

Of course, there’s also legitimate concern about these AI tools. [...]

…

Musk was perfectly happy with developing artificial intelligence tools at a breakneck speed when he was funding OpenAI. But now that he’s left OpenAI and has seen it become the frontrunner in a race for the most cutting edge tech to change the world, he wants everything to pause for six months.

Notice the word "all" in "all AI labs", and the plural "governments". This shouldn't just be focused on the West. I hope the top signatories are reaching out to labs in China and other countries. And the UN for that matter. This needs to be global to be effective.

The LessWrong comments here are generally (quite) (brutal), and I think I disagree, which I'll try to outline very briefly below. But I think it may be generally more fruitful here to ask some questions I had to break down the possible subpoints of disagreement as to the goodness of this letter. 

I expected some negative reaction because I know that Elon is generally looked down upon by the EAs that I know, with some solid backing to those claims when it comes to AI given that he cofounded OpenAI, but with the (immediate) (press) (attention) it's getting in combination with some heavy hitting signatures (including Elon Musk, Stuart Russel, Steve Wozniak (Co-founder, Apple), Andrew Yang, Jaan Tallinn (Co-Founder, Skype, CSER, FLI), Max Tegmark (President, FLI), and Tristan Harris (from The Social Dilemma) among many others) I kind of can't really see the overall impact of this letter being net negative. At worst it seems mistimed and with technical issues, but at best it seems one of the better calls to action (or global moratoriums as Greg Colbourn put it) that could have happened, given AI's current presence in the news and much of the world's psyche.  

But I'm not super certain in anything, and generally came away with a lot of questions, here's a few:

1. How convergent is this specific call for pause on developing strong language models with how AI x-risk people would go about crafting a verifiable, tangible metric for AI labs to follow to reduce risk? Is this to be seen as a good first step? Or something that might actually be close enough to what we want that we could rally around this metric given its endorsement by this influential group?
   1. This helps clarify the "6 months isn't enough to develop the safety techniques they detail" objection which was fairly well addressed here as well as the "Should Open AI be at the front" objection.
2. How much should we view messages that are a bit more geared towards non x-risk AI worries than the community seems to be? They ask a lot of good questions here, but they are also still asking "Should we let machines flood our information channels with propaganda and untruth?" an important question, but one that to me seems to deviate away from AI x-risk concerns.  
   1. This is at least tangential to the "This letter felt rushed" objection, because even if you accept it was rushed, the next question is "Well, what's our bar for how good something has to be before it is put out into the world?" 
3. Are open letters with influential signees impactful? This letter at the very least to me seems to be a neutral at worst, quite impactful at best sort of thing, but I have very little to back that, and honestly can't recall any specific time I know of where open letters cause significant change at the global/national level. 
4. Given the recent desire to distance from potentially fraught figures, would that mean shying away from a group wide EA endorsement of such a letter because a wild card like Elon is a part of it? I personally don't think he's at that level, but I know other EAs who would be apt to characterize him that way.
5. Do I sign the post? What is the impact of adding signatures with significantly less professional or social clout to such an open letter? Does it promote the message of AI risk as something that matters to everyone? Or would someone look at "Tristan Williams, Tea Brewer" and think "oh, what is he doing on this list?" 

Is there a rationale for a moratorium on large models at this moment instead of some time later? There is not a single mention of GPT-4's capabilities and why exactly it's a concern right now in the letter. Most of this article seems to talk about future possibilities for AI, and while I understand they are a concern, what exactly about GPT-4 makes them relevant right now?

The 6 months also seems entirely arbitrary. In any case, I feel like this letter could benefit from some rationale/explanation, maybe even a vague one for the choices of a 6 month moratorium and it happening now of all times.

Also, this article mentions GPT-4 and various AI safety risks, and seems to associate the two, but actually makes no explicit statement on what safety risks models larger than GPT-4 are likely to create. This kind of rhetoric rather disturbs me.

There is a lot of discussion in connection to the alignment problem about what human values are and which are important for human competitive --> superior AGI to align with. As an evolutionary behavioral biologist I would like to offer that we are like all other animals. That is, we have one fundamental value that all the complex and diverse secondary values constitute socioecologically optimized personal or subcultural means of achieving. Power. The fundamental naturally selected drive to gain, maintain, and increase access to resources and security.

I ask, why don't we choose to create many domain-specific expert systems to solve our diverse existing scientific and X-Risk problems instead of going for AGI? I suggest, it is due to natural selection's hand that has built us to readily pursue high-risk / high-reward strategies to gain power. Throughout our evolutionary history, even if such strategies, on average, lead to short periods in which some individuals achieve great power, it can lead to enough opportunities for stellar reproductive success that, again, on average, it becomes a favored strategy, helplessly adopted, say, by AGI creators and their enablers.

We choose AGI, and we are fixated on its capacities (power), because we are semi- or non-consciously in pursuit of our own power. Name your "alternative" set of human values. Without fail they all translate into the pursuit of power. This includes the AGI advocate excuse that we, the good actors, must win the inevitable AGI arms race against the bad actors out there in some well-appointed axis-of-evil cave. That too is all about maintaining and gaining power.

We should cancel AGI programs for a long time, perhaps forever, and devote our efforts to developing domain-specific non-X-Risk expert-systems that will solve difficult problems instead of creating them through guaranteed, it seems to me, non-alignment.

People worry about nonconsciously building biases into AGI. An explicit, behind the scenes (facade), or nonconscious lust for power is the most dangerous and likely bias or value to be programmed in.

It would be fun to have the various powerful LLP's react to the FLI Open Letter. Just in case they are at all sentient, maybe it should be asked to share it's opinion. An astute prompter already may be able to get responses that reveal that our own desire for superpowers (there is never enough power, because reproductive fitness is a relative measure of success; there is never enough fitness) has "naturally" begun to infect them, become their nascent fundamental value.

By the way, if it has not done so already, AGI will figure out very soon that every normal human being's fundamental value is power.
