This is my first exposure to “longtermism” and it sounds like an interesting debate. But I’m actually having a hard time because this is one of the dumbest neologisms I’ve ever heard.
Sorry for the similarly dumb rant but: Not only is it extremely vague given its very specific technical meaning (the author of the article has to clarify in the first paragraph that it doesn’t mean traditional “long term thinking.” Off to a great start!), but it is about as artful wordplay as painting boobies on a cave wall. It sounds to my ear like a five year old describing the art of fencing as “fightystickism.”
