PhD Student in Philosophy at the London School of Economics, researching Moral Progress and the causes that drive it.
Previously, I did a MA in Philosophy at King’s College London and a MA in Political Philosophy at Pompeu Fabra University (Spain). More information about my research at my personal website: https://www.rafaelruizdelira.com/
From time to time, I write on my blog: https://themoralcircle.substack.com/
You might also know me from EA Twitter. :)
One reason is that longtermists are largely philosophers, who have no particular expertise on the details of aligning AI.
Another reason worth taking into consideration is if the true moral view is “fussy”, rather than “easygoing”. If you’re “easygoing” in what you consider utopia, then, conditional on survival, most achievable value gets realized by default (we get great human lives), and extinction is the one really action-relevant lock-in event. But if you’re fussy about realizing the best possible utopia, then, conditional on survival, we’re still likely to miss most achievable value across a huge swathe of futures (we don’t tile the universe with happy digital minds, say, or whatever crazy future might be the best utopia). The space of “didn’t go extinct but missed most of the value” turns out to be enormous, and some of the features determining where in that space we land (early decisions about digital minds, population-ethics, allocation of resources during space settlement, which value-systems get amplified during the AI transition) are themselves plausibly locked-in, even if they don’t feel as salient as extinction.
(But then again, maybe I’m recency biased because I just re-read Better Futures for the discussion week here on the Forum)
That doesn’t settle the prioritization, and, like, the people are Forethought and 80.000 Hours are directly and explicitly working on the AI transition? So it’s not like x-risk is off the table. My vibe for highly-engaged EAs is that perhaps it just feels that the main arguments about x-risk have already been made.
