That's not just with LLMs. This has been an Achille's heel of demos for decades.

It's usually quite easy to make a demo of something sexy, but making it ship, is a very, very different thing.

This is made exponentially worse, by managers thinking that the demo means "we're almost ready," and even by the engineers, themselves, who are often not experienced enough to understand that demo != ship. Also, it has been my experience, that researchers that come up with amazing ideas, have absolutely no appreciation for what it takes to turn their ideas into ship product. Since Apple is all about ship product, they have to bridge that gulf. They are trying to commoditize something that is mostly buzz and raw research, right now.

I'm really pretty jaded about ML and LLMs in general, right now. I feel as if a whole bunch of really sexy demos were released, creating a huge level of buzz, but that the shipping product is still a ways off.
