@iju What you might have encountered is ”rationalism” in the modern Silicon Valley definition of the word.
Yudkowsky’s rationalism argues for things like longtermism in which future humans are more important than present humans, dismissing the moral implications of such thinking out of hand.
It’s my opinion that Silicon Valley has made a religion of it’s moral choices & ideals. But without enough humanists in the fold, they’re not capable of seeing they’re acting out of faith.
