TL;DR: Many alignment research proposals often share a common motif: figure out how to enter a basin of alignment / corrigibility for human-level models, and then amplify to more powerful regimes while generalizing gracefully. In this post we lay out a research agenda that comes at this problem from a different direction: if we already have ~human-level systems with extremely robust generalization properties, we should just amplify those directly. We’ll call this strategy “Gradient Descent on the Human Brain”.

Introduction.

Put one way, the hard part of the alignment problem is figuring out how to solve ontology identification: mapping between an AI's model of the world and a human's model, in order to translate and specify human goals in an alien ontology.

In generality, in the worst case, this is a pretty difficult problem. But is solving this problem necessary to create safe superintelligences? The assumption that you [...]
