Personally I disagree with this. I've been using LLMs the last few years and learning a lot about techniques for getting value out of them. Even though they weren't very good for a while they seemed worth learning to me because the rate of improvement was so fast. We've now reached a point where if you know how to use them right you can get lots of value out of them.
I really don't mean to be rude here but consider perhaps the reason why you're having trouble seeing why they're valuable is because you haven't used them enough in the last few years or kept up with the developments closely enough. Maybe I'm wrong. But consider it's possible you are too.

I'm sure others have said that but my perspective has been that the models are not quite good enough yet, for a while but that the trajectory is so crazy that it made sense to make the bet and invest lots of time into learning how to use them on the assumption that they would soon be good.
Even now I would say they have a long way to go. What is hard but possible today will be easy tomorrow. But quite a lot is now possible with the right techniques. Crazy things.
