The good equivalent example is translation. You would expect Google Translate to make translators redundant. However, they are busier than ever. As they can now translate documents a lot faster, it becomes more economical for companies to translate documents.

Regarding job gains, we initially will see a whole bunch of snake oil sales people selling AI.

Err.. but AI has pretty much obsoleted most translation work. Of course, well-written poetry and prose will still need to be translated by an expert in both languages, as well as possibly literature and linguistics. But even then, GPT-4 may be better than this person some of the time.

Absolutely not. OpenAI can't be taken to court if a mistranslation causes issues. That is why it will always require a human to confirm the translation is correct.

As discussed before, OpenAI doesn't know it doesn't know, and will dream up something.

Gonna be prompt engineers (and human langchains)
