That is true, but it was a term narrowly and incoherently used by scientists. In fact, that one paper used it, and it took ten years for it to be picked up again, again by just a few academic papers. Even the academic community preferred terms like “strong AI” before the current hype.

AGI was not a term that was used to refer to a concept, it had to be explained by each and every article that mentioned it, it was not a general term that had a strict meaning attached to it. It was brought to that level by Google/Deepmind employees two years ago, and then got into the place where every second Medium article is buzzwording around with it when it became a corporate target for OpenAI/Microsoft.
