It’s not “just like”, because humans can be held accountable. Also, I suspect that the distribution of failure modes is actually substantially different between LLMs and humans.
So, to avoid depressed AIs ending the world randomly, have a stable of multiple AIs with different provenance (one from Anthropic, one from OpenAI, one from Google...) require a majority agreement to reduce the error rate. Adjust thresholds depending on criticality of the task at hand.
