Useful if you understand how they work and what they are good at

They're very useful, but just for certain things. The problem is that every corpo idiot out there thinks they're useful for everything, which they're most certainly not.

They're ok, just pretty limited in what they can do. Doesn't help i also have to fact check them.

My use cases thus far have been pretty minimal. Stuff like OCR extraction of tables from images (which were possible before LLM's), very occasional reformatting of lists and stuff, some of the built in summarization features which provide tiny value. I've never actually used them to write something for me. The one time I considered it I found something better already written.
