Which alternatives to EV have what problems for what uses in what contexts?
Why do those problems make them worse than EV, a tool that requires the use of numerical probabilities for poorly-defined events often with no precedent or useful data?
What makes all alternatives to EV less preferable to the way in which EV is usually used in existential risk scholarship today, where subjectively-generated probabilities are asserted by "thought leaders" with no methodology and no justification, about events that are not rigorously defined nor separable, which are then fed into idealized economic models, policy documents, and press packs?
Honestly, fair enough.
