I think the "step-function" thing is more that he believes that these things will follow exponential/logistic curves, which can easily look like step-functions to humans, but are still perfectly lawful and continuous.
This is completely different from my Eliezer-model. My Eliezer-model says:
Quoting EY:
[...] Before anybody built the first critical nuclear pile in a squash court at the University of Chicago, was there a pile that was almost but not quite critical? Yes, one hour earlier. Did people already build nuclear systems and experiment with them? Yes, but they didn't have much in the way of net power output. Did the Wright Brothers build prototypes before the Flyer? Yes, but they weren't prototypes that flew but 80% slower.
I guarantee you that, whatever the fast takeoff scenario, there will be some way to look over the development history, and nod wisely and say, "Ah, yes, see, this was not unprecedented, here are these earlier systems which presaged the final system!" Maybe you could even look back to today and say that about GPT-3, yup, totally presaging stuff all over the place, great. But it isn't transforming society because it's not over the social-transformation threshold.
AlphaFold presaged AlphaFold 2 but AlphaFold 2 is good enough to start replacing other ways of determining protein conformations and AlphaFold is not; and then neither of those has much impacted the real world, because in the real world we can already design a vaccine in a day and the rest of the time is bureaucratic time rather than technology time, and that goes on until we have an AI over the threshold to bypass bureaucracy.
[...] There is not necessarily a presage of 9/11 where somebody flies a small plane into a building and kills 100 people, before anybody flies 4 big planes into 3 buildings and kills 3000 people; and even if there is some presaging event like that, which would not surprise me at all, the rest of the world's response to the two cases was evidently discontinuous. You do not necessarily wake up to a news story that is 10% of the news story of 2001/09/11, one year before 2001/09/11, written in 10% of the font size on the front page of the paper.
Physics is continuous but it doesn't always yield things that "look smooth to a human brain". Some kinds of processes converge to continuity in strong ways where you can throw discontinuous things in them and they still end up continuous, which is among the reasons why I expect world GDP to stay on trend up until the world ends abruptly; because world GDP is one of those things that wants to stay on a track, and an AGI building a nanosystem can go off that track without being pushed back onto it.
[Cross-posting from the EA Forum]
Epistemic status: Personal anecdotal evidence, not fully thought through to my own satisfaction. I'm posting this anyway because if I wait until I've thought it through to my satisfaction then I might never post it at all.
People keep telling me how they've had trouble convincing others to care at all about AI risk, or to take the concerns about misaligned AI seriously. This has puzzled me somewhat, because my experience has been significantly different than that.
In my case I mostly talk to engineers who deal with real-world applications of current or near-future AI systems, and when I talk to them about AI safety I actually don't focus on existential risks at all. Instead I just talk about the risks from the systems we have right now, and the challenges we face in making them safe for today's safety- and mission-critical systems. So I'll talk about things like specification gaming, negative side effects, robustness, interpretability, testing and evaluation challenges, security against adversaries, and social coordination failures or races to the bottom. And then at the end I'll throw in something about, oh yeah and obviously if we scale up AI to be even more powerful optimizers than they are now, then clearly these problems can have potentially catastrophic consequences.
And the thing is, I don't recall getting just about any pushback on this - including on the longer term risks part. In fact, I find that people tend to extrapolate to the existential risks on their own. It really is pretty straightforward: There are huge problems with the safety of today's AI systems that are at least partly due to their complexity, the complexity of the environment they're meant to be deployed in, and the fact that powerful optimizers tend to come up with surprising and unforeseen solutions to whatever objectives we give them. So as we build ever more complex, powerful optimizers, and as we attempt to deploy them in ever more complex environments, of course the risks will go way up!
Sometimes I'll start adding something about the longer term existential risks and they'll be like, "whoah, yeah, that's going to be a huge problem!" And sometimes they do the extrapolation themselves. Sometimes I'll actually immediately follow that up with reasons people have given why we shouldn't be worried... and the people I'm talking to will usually shoot those arguments down immediately on their own! For example, I might say something like, "well, some have argued that it's not such a worry because we won't be stupid enough to deploy really powerful systems like that without the proper safeguards..." And they'll respond with incredulous faces, comments like, "yeah, I think I saw that movie already - it didn't end well," and references to obvious social coordination failures (even before the pandemic). Depending on how the conversation goes I might stop there, or we might then get a bit more into the weeds about specific concerns, maybe mention mesa-optimization or the like, etc. But at that point it's a conversation about details, and I'm not selling them on anything.
Notice that nowhere did I get into anything about philosophy or the importance of the long term future. I certainly don't lead with those topics. Of course, if the conversation goes in that direction, which it sometimes does, then I'm happy to go into those topics. - I do have a philosophy degree, after all, and I love discussing those subjects. But I'm pretty sure that leading with those topics would be actively counterproductive in terms of convincing most of the people I'm talking to that they should pay attention to AI safety at all. In fact, I think the only times I've gotten any real pushback was when I did lead with longer-term concerns (because the conversation was about certain projects I was working on related to longer-term risks), or when I was talking to people who were already aware of the philosophy or longtermist arguments and immediately pattern-matched what I was saying to that: "Well I'm not a Utilitarian so I don't like Effective Altruism so I'm not really interested." Or, "yeah, I've heard about Yudkowsky's arguments and it's all just fear-mongering from nerds who read too much science fiction." Never mind that those aren't even actual arguments - if I've gotten to that point then I've already lost the discussion and there's usually no point continuing it.
Why do I not get pushback? I can think of a few possibilities (not mutually exclusive):
Here's a presentation I gave on this topic a few times, including (in an abridged version) for a Foresight Institute talk. Note that the presentation is slightly out of date and I would probably do it a bit differently if I were putting it together now. Relatedly, here's a rough draft for a much longer report along similar lines that I worked on with my colleague I-Jeng Wang as part of a project for the JHU Institute for Assured Autonomy. If anybody is interested in working with me to flesh out or update the presentation and/or report, please email me (aryeh.englander@jhuapl.edu).
