I've always considered AI as a much more complex concept than simply appearing to be human in speech or text. Extremely complex prediction algorithms that appear on the surface to be creative wouldn't have met my bar either.
An LLM can predict how a human may write a white paper, for example. It will sound impressive, but the model and related algorithms seem to have absolutely no way of logically working through a problem or modelling the world to know if the ideas proposed in the paper might work. Its a really impressive sounding impersonator, but it is nothing like intelligence.
