It performs no reasoning, and instead predicts the next token 

If we had a nickel for every misguided repetition of this non sequitur we'd have another $10. GPT-4 is far beyond markov chain predictions and Eliza. While technically Eliza, GPT-4 and Photoshop operate on the same principles of assembly instructions, and GPT-4 indeed does token predictions, this says nothing about the inner architecture and reasoning capabilities. GPT-4 internally is a functionally complete state machine, or would be on an unlimited token stream.
