There is a big difference between (i) the very plausible claim that the value of the long-term (in terms of lives, experiences, etc.) is astronomically larger than the value of the near-term, and (ii) the rather implausible claim that interventions targeted at improving the long-term are astronomically more important/cost-effective than those targeted at improving the near-term. It seems to me that many longtermists believe (i) but that almost no-one believes (ii).
Basically, in this context the same points apply that Brian Tomasik made in his essay “Why Charities Usually Don’t Differ Astronomically in Expected Cost-Effectiveness” (https://reducing-suffering.org/why-charities-dont-differ-astronomically-in-cost-effectiveness/)
Agreed, I’d love this feature! I also frequently rely on pageview statistics to prioritize which Wikipedia articles to improve.
