“There is a conceivable world where there is no intelligence explosion and no superintelligence. Or where, a related but logically distinct proposition, the tricks that machine learning experts will inevitably build up for controlling infrahuman AIs carry over pretty well to the human-equivalent and superhuman regime. Or where moral internalism is true and therefore all sufficiently advanced AIs are inevitably nice. In conceivable worlds like that, all the work and worry of the Machine Intelligence Research Institute comes to nothing and was never necessary in the first place, representing some lost number of mosquito nets that could otherwise have been bought by the Against Malaria Foundation.
There’s also a conceivable world where you work hard and fight malaria, where you work hard and keep the carbon emissions to not much worse than they are already (or use geoengineering to mitigate mistakes already made). And then it ends up making no difference because your civilization failed to solve the AI alignment problem, and all the children you saved with those malaria nets grew up only to be killed by nanomachines in their sleep.
[I] think that people who try to do thought-out philanthropy, e.g., Holden Karnofsky of GiveWell, would unhesitatingly agree that these are both conceivable worlds we prefer not to enter. The question is just which of these two worlds is more probable as the one we should avoid.
[I] think it’s the first world that’s improbable and the second one that’s probable. I’m aware that in trying to convince people of that, I’m swimming uphill against a sense of eternal normality – the sense that this transient and temporary civilization of ours that has existed for only a few decades, that this species of ours that has existed for only an eyeblink of evolutionary and geological time, is all that makes sense and shall surely last forever. But given that I do think the first conceivable world is just a fond dream, it should be clear why I don’t think we should ignore a problem we’ll predictably have to panic about later.”
