You are not directly vouching for anyone here, but as a general point I’d like to argue that friendship is a poor predictor of ethical behavior.
It may be tempting to consider positive social experiences and friendship as evidence that someone behaves generally ethically and with high standards, but when dealing with more capable people, it’s not. Maintaining ethical behavior and building trust in low-stakes settings like friendship with few temptations to try and exploit for profit is trivially easy. Especially if you are socially skilled and capable of higher level power games and manipulation. The cutthroat moves are saved exclusively for situations where the profits are large enough.
(And a skilled manipulator will rarely engage in obviously cutthroat moves anyways, because the cost of being outed as an unethical cutthroat is high enough to outweight the potential profit of most situations..)
Because you’re someone with influence in the community, anyone with a manipulative bent and any smarts will absolutely give you their best impression. You have more value as an ally, and probably provide few opportunities for direct profit otherwise.
This bolded part is a bit difficult to understand. Or at least I can’t understand what exactly is meant by it.
“lightcone” is an obscure term, and even within Less Wrong I don’t see why the word is clearer than using “the future” or “the universe”. I would not use the term with a lay audience.
