“GPT surpasses all ... when it comes to conversation, research, and writing. ... creating an algo[rithm] that sells stocks based on a large training set of materials, correlations to past crises, and commonsense heuristics aimed at not being the last one out of a burning barn is trivial. The danger ... is not in the single system but in the resonance of millions of similar systems doing the same thing at the same time. No science fiction is needed.”
