Is this an Effective Altruism thing, or some other Silicon Valley trend? The amount of times I've seen it suggested that non-productive members or society should be euthanized on HN is so much higher than I would have ever thought it would be. And people always say something similar how it's just a taboo, but if you think rationally you'd naturally off everyone who isn't making money. I'm always curious how they arrive at that line of thinking.
