We've been working with it for over a year now and I'm of the mind that AI, in it's current state, really isn't a tool meant for an end user to interact with.
It feels like it's the most useful when it's transparent and you -- as an end user -- don't know that there's an LLM in the process. The best use cases seem to be those that don't require an end consumer to directly interact with an AI, but their journey through some process is assisted by an AI instead.
The problem is that a lot of the marketing -- like these examples and Google's very misguided "Write me a letter" to an Olympian -- exists because companies keep trying to make "fetch" happen; the AI becomes the journey instead of being an assistant in that journey.
Amazon's Rufus is a prime example. It's tucked away as a button that one has to activate explicitly. But it would almost be better if it could just clean up the search results when I do a search and a bunch of junk is returned.
