The tweet rants that Anthropic has an unwritten in-house group norm heavily shaped by effective altruism (EA) and a so-called 'Harry Potter-style doomsday' worldview. The author argues this culture prevents the company from aligning with its customers' goals, since in such a 'cult' atmosphere only ML engineers steeped in EA thinking are considered to matter. The author calls it a textbook case of Western utopianism gone off the rails.
