In terms of the thesis of Incorruptible, though, I do think that LLMs in particular should be really, really advantageous for managers and leaders who want to create alignment and coherence within their own company. If there's anything that LLMs are extremely good at, it's summarization. So much of the modern leadership challenge is simply figuring out the answer to the question: what is my organization actually doing right now? That's a summarizing problem.
I would not think that LLMs would make very good leadership decisions, mostly because they're too malleable and too easy to manipulate. I do think they're very helpful in helping leaders assess their own context and situation and thereby make better decisions.
