Idiots thinking a new thing is magic that will solve all the worlds problems doesn't mean the thing doesn't have merit. Someone calling themselves an exper carpenter because they have a nailgun doesn't make nailguns any less useful.

If you see a person doing a data entry job, do you walk over to them, crack their head open and say "aww man, it's not magic, it's just a blob of fat capable of reading and understanding a document, and to then plot the values into a spreadsheet"?

It's not magic, it's not a super intelligence that will solve everything, it's the first tool we've been able to make that can be told what to do in human language, and able to then perform tasks with a degree of intelligence and critical thinking, something that normally would require either a human or potentially years of development to automate programmatically. That alone makes it very useful
