AI is a marketing term to explain generative text and predictive text to non-technical people, much like Hacker was re-used and ab-used to describe someone who broke into computer systems in the 80s.
I think you underestimate the power of generative text. It is NOT AI. When its used as a tool to generate text, its amazingly powerful. It can save a ton of time getting a framework and outline in place prior to you putting the meat on the bones.
I also think the proper way to use this tool will be akin to something like, here's a metaphor for sculpture, where you say "I want to carve a horse" and the 'magic AI for sculpture' will grab a stone block of the right properties and whittle away a general horse shape in the way you want. Could you make the details exact with generative help? Possibly but that will be the difference between crap AI work that broaches on copyright violation and actual creations with a human touch.
Business is going to be very very interested in a tool that can detect more accurately things generated ML, and attorneys more so - the very heart of legal contract and copyright is at stake. The hype will not die down, nor will investment. We may see an ML-style dot-com bubble burst but that didn't kill the web - it made it better.
Transformers based generative text can double the productivity or more of a programmer or technical writer but it cannot yet replace them - and no one is currently claiming otherwise.
