Many prominent artificial intelligence experts, including Tesla CEO Elon Musk, have signed an open letter calling for a six-month pause in developing systems more powerful than OpenAI's newly launched GPT-4 (Generative Pre-Trained Transformer). But a notable name is missing from the long list of signatures.

As of Wednesday, OpenAI CEO Sam Altman's name remains absent from the letter, and his comments about the concerns expressed in it suggest he has no plans to call for any sort of halt to AI development.
