You don't even have to look at other "fads" like 3D televisions and VR to be skeptical of the claim that recent advancements in ML* represent a major technological revolution that will change society like the Internet or the Printing Press did.
Just look at ML's own history. A few years ago we had the "deepfake" scare. People were terrified that now videos are going to surface of politicians saying and doing things that they did not and we would have no way to tell if it was AI generated or not. But we had already been dealing with this for decades with doctored images a la Photoshop. Videos could already be edited by human beings to make it look like someone was communicating a message that they were not.
What we have now is a tool that is able to generate text-based content that is indistinguishable from that written by an 8th grader. Even with inevitable improvements that get us to 12th grade level, so what?
People will use ChatGPT to write emails and code for them. Personally I don't see the appeal since I am a very creative person and don't want to outsource that work to a human let alone software, but who cares? Currently I can tell when people that I know well are using ChatGPT to "refine" their writing to me, but the content is what matters anyway and I don't know anyone who says they don't "massage" the ChatGPT output for correctness first.
Certain people will find creative uses like generating SEO content for websites etc. That's a problem for the search engines. Basically the Internet is about to get noisier .. but it was already so noisy that the older I get the less attention I'm starting to pay to it, in general, anyway.
Then again, I am limited by my own imagination. Maybe people will come up with truly "disruptive" ways to use LLMs ... but meh. Same shit different day IMO.
* and let's be honest here, ML is a MUCH more accurate term for what we have than AI ... though it's not as good of a marketing term since ML doesn't put "The Matrix" or "The Terminator" in the minds of the lay public like "AI" does.
