Investors should optimize for long term growth, yes. The problem is Management (CEO, etc.) will get fired if things look bad. So the incentive for management, if they can get fired, is to ensure monotonic increase. Sometimes — especially for a rocket company! — you should be allowed to fail for a few years. You should be allowed to take big swings, without risk of getting fired. If Elon knows he is in control, he can think long-term. If he's at risk of being let go if things look bleak, his optimization function will be different (and, IMO, net worse for society).
You can either concentrate power or disperse it. NASA, Boing, etc. is what happens when you disperse it. Committees aren't bold. The reason SpaceX exists is because Elon willed it into existence.
We (macro.com) have something similar but without the recipe part in our pdf/word processor. It works pretty well on numbered headings but not so well on non-numbered. We’re thinking of porting over to LLMs at some point.
