An underrated success story which I find more plausible than moral circle expansion is that human concern for animal welfare (both wild and farmed animal welfare) remains low, but due to a combo of causal moral trade and acausal trade like Evidential Cooperation in Large Worlds, animals/animal advocates across the multiverse get most of what they want because it’s cheap and easy to coordinate.
In general, I notice that trade-based futures aren’t shown, when I tend to think they are by far the most likely way most beings get most of what they want almost regardless of values, if we can somehow prevent threats/blackmail from eating into expected value.
At least re the Epoch ECI vs METR’s time horizons, I’m pretty certain they’re expressing the same thing, but in different units, and linear ELO/ECI progress in a Bradley-Terry model is exactly the same as exponential improvements.
I haven’t read much of the rest of the article, so I can’t decide whether it’s right, but I do think that there is likely a mistake in differentiating the progress rates based on ECI vs Time Horizons.
