Re: glorified autocomplete
People that have zero understanding use this and their belittling intentions are clear.
People that have a vague understanding think there is something else truly magical.
People that have a bit more understanding such as Yann lecun say "glorified autocomplete" (or similar) and mean that no matter what behaviour you "bootstrap" out of the autocomplete process(conversation, search, etc) you're, at end, limited by the mechanics of next word prediction.
Sort of like that popular normal distribution meme.
Whether this is sufficient for AGI or not is still a matter of definition and opinion of course.
