> Not everyone is a fan of longtermism. I can’t think of a reason why. I mean, the last time a self-declared intellectual elite said it’s okay to sacrifice some million people for the greater good, only thing that happened was a world war, just a "small misstep for mankind."

Our culture, in general and implicitly, rejects the idea of objective truth in favor of hedonism.

If we're living for pleasures of the moment, then fretting about the unborn seems silly. Look at government borrowing: we're reducing future generations to penury because of whatever folly sounded good for the election.

Neither "Effective Altruism" or "Longtermism" seem more than fads, and for the same reason: without an internal renewal based upon some immutable, external truth, these movements shall not outlive their founders.
