To me it's just a new way of representing information that makes information on the web easily accessible to people. So in a way it's a breakthrough just like Google was a breakthrough. Google's pagerank represented the web as a graph and you could easily go to related pages. Gpts embed concepts in a high dimensional space and there are links between them that makes it easy to query this knowledge représentation. So I don't think it will replace humans so much as disrupt the knowledge industry just like Google
