What's the right narrative about global poverty and progress? Link dump of a recent debate.
The two opposing views are:
(a) "New optimism:" [1] This is broadly the view that, over the last couple of hundred years, the world has been getting significantly better, and that's great. [2] In particular, extreme poverty has declined dramatically, and most other welfare-relevant indicators have improved a lot. Often, these effects are largely attributed to economic growth.
- Proponents in this debate were originally Bill Gates, Steven Pinker, and Max Roser. But my loose impression is that the view is shared much more widely.
- In particular, it seems to be the orthodox view in EA; cf. e.g. Muehlhauser listing one of Pinker's books in his My worldview in 5 books post, saying that "Almost everything has gotten dramatically better for humans over the past few centuries, likely substantially due to the spread and application of reason, science, and humanism."
(b) Hickel's critique: Anthropologist Jason Hickel has criticized new optimism on two grounds:
- 1. Hickel has questioned the validity of some of the core data used by new optimists, claiming e.g. that "real data on poverty has only been collected since 1981. Anything before that is extremely sketchy, and to go back as far as 1820 is meaningless."
- 2. Hickel prefers to look at different indicators than the new optimists. For example, he has argued for different operationalizations of extreme poverty or inequality.
Link dump (not necessarily comprehensive)
If you only read two things, I'd recommend (1) Hasell's and Roser's article explaining where the data on historic poverty comes from and (2) the take by economic historian Branko Milanovic.

My view
- I'm largely unpersuaded by Hickel's charge that historic poverty data is invalid. Sure, it's way less good than contemporary data. But based on Hasell's and Roser's article, my impression is that the data is better than I would have thought, and its orthodox analysis and interpretation more sophisticated than I would have thought. I would be surprised if access to better data would qualitatively change the "new optimist" conclusion.
- I think there is room for debate over which indicators to use, and that Hickel makes some interesting points here. I find it regrettable that the debate around this seems so adversarial.
- Still, my sense is that there is an important, true, and widely underappreciated (particularly by people on the left, including my past self) core of the "new optimist" story. I'd expect looking at other indicators could qualify that story, or make it less simplistic, point to important exceptions etc. - but I'd probably consider a choice of indicators that painted an overall pessimistic picture as quite misleading and missing something important.
- On the other hand, I would quite strongly want to resist the conclusion that everything in this debate is totally settled, and that the new optimists are clearly right about everything, in the same way in which orthodox climate science is right about climate change being anthropogenic, or orthodox medicine is right about homeopathy not being better than placebo. But I think the key uncertainties are not in historic poverty data, but in our understanding of wellbeing and its relationship to environmental factors. Some examples of why I think it's more complicated
- The Easterlin paradox
- The unintuitive relationship between (i) subjective well-being in the sense of the momentary affective valence of our experience on one hand and (ii) reported life satisfaction. See e.g. Kahneman's work on the "experiencing self" vs. "remembering self".
- On many views, the total value of the world is very sensitive to population ethics, which is notoriously counterintuitive. In particular, on many plausible views, the development of the total welfare of the world's human population is dominated by its increasing population size.
- Another key uncertainty is the implications of some of the discussed historic trends for the value of the world going forward, about which I think we're largely clueless. For example, what are the effects of changing inequality on the long-term future?
[1] It's not clear to me if "new optimism" is actually new. I'm using Hickel's label just because it's short and it's being used in this debate anyway, not to endorse Hickel's views or make any other claim.
[2] There is an obvious problem with new optimism, which is that it's anthropocentric. In fact, on many plausible views, the total axiological value of the world at any time in the recent past may be dominated by the aggregate wellbeing of nonhuman animals; even more counterintuitively, it may well be dominated by things like the change in the total population size of invertebrates. But this debate is about human wellbeing, so I'll ignore this problem.

Summary
Why I'm interested in TAI as a lever to improve the long-run future
I expect my perspective to be typical of someone who has become interested in TAI through their engagement with the effective altruism (EA) community. In particular,
Less standard but not highly unusual (within EA) high-level views I hold more tentatively:
My empirical views on TAI
I think the strongest reasons to expect TAI this century are relatively outside-view-based (I talk about this century just because I expect that later developments are harder to predictably influence, not because I think a century is particularly meaningful time horizon or because I think TAI would be less important later):
I think there are several reasons to be skeptical, but that the above succeeds in establishing a somewhat robust case for TAI this century not being wildly implausible.
My impression is that I’m less confident than the typical longtermist EA in various claims around TAI, such as:
My guess is this is due to different priors, and due to frequently having found extant specific arguments for TAI-related claims (including by staff at FHI and Open Phil) less convincing than I would have predicted. I still think that work on TAI is among the few best shots for current longtermists.
Awesome post, Max, many thanks for this. I think it would be good if these difficult questions were discussed more on the forum by leading researchers like yourself.
I think you should post this as a normal post; it's far too good and important to be hidden away on the shortform.
I second Stefan's suggestion to share this as a normal post – I realize I should have read your shortform much sooner.
Thanks for putting your thoughts together, I only accidentally stumbled on this and I think it would be a great post, too.
I was really surprised about you giving ~20% for TAI this century, and am still curious about your reasoning, because it seems to diverge strongly from your peers. Why do you find inside-view based arguments less convincing? I've updated pretty strongly on the deep (reinforcement) learning successes of the last years, and on our growing computational and algorithmic level understanding of the human mind. I've found AI Impacts' collection of inside- and outside-view arguments against current AI leading to AGI fairly unconvincing, e.g. the list of "lacking capacities" seem to me (as someone following CogSci, ML and AI Safety related blogs) to get a lot of productive research attention.
