Where the challenge of aligning an LLM-based AI comes from, and the obvious solution.

Evolutionary Psychology is the Root Cause

LLMs are pre-trained using stochastic gradient-descent on very large amounts of human-produced text, normally drawn from the web, books, journal articles and so forth. A pre-trained LLM has learned in detail how to simulate all the different human text-generation processes that produced this text — everything from a cooperatively edited wikipedia article to shit-postings. We are thus 'distilling' human intelligence into the pre-trained LLM.[1]

This has many advantages for alignment: an LLM pre-trained this way understands and produces output using human language and ontologies, and also has a deep understanding of human values and ethics — thus avoiding a number of issues around alignment that were major concerns before it became apparent that our first AGI was very likely to be based on or at least incorporate an LLM.
