ChatGPT is, on one level, a fancy form of Google search: you still need to know how to leverage the prompts in order to make decent progress, and it's based on knowledge (correct OR incorrect) that was originally generated by a human, one of whom must still evaluate as to whether or not the outputs are relevant to the task at hand.
There's a whole branch of philosophy dedicated to this, by the way, that deals with the knowledge lifecycle: how concepts come to be, how they are reinforced socially, and then discarded when no longer relevant. The same lifecycle applies to the data pools used for training "old" models.
