There are plans to use longtermism (both the term and the idea) in disciplines beyond moral philosophy (e.g. the Global Priorities Institute’s longtermist research agenda which includes economics in addition to philosophy). So to “prevent confusion”, it’s important to understand whether other fields are using the term, and what other people are likely to think when they hear it.
FWIW, I think for most people something like “ultralongtermist” would do a better job of communicating the time frames Will is talking about.
