I don't think that the parent comment argued that they are, but okay.

I think they did. They specifically said how a new tool is available and putting things into reach for people that previously wasn't. In the context about creating art, that reads to me like they do mean that prompters are considered the creators.

Can you consider a movie director to be the creator of a movie? They are just telling other people what to do.

If the "only" thing the director is doing, in the most literal sense, is directing then no, I don't.

I'm not an expert in media production though but from the sparse amount of interviews I have seen a lot also write the scripts and are involved in a lot more than just directing.

I think ultimately this is just something we disagree on :)
