I think the hype of generative AI will eventually lose its luster and people will move on. Though, I think it will retain some uses and be implemented in many sectors, I don't see it maintaining its hype beyond a couple of years. People will eventually get hyped over the next big thing. This is what is happening to the metaverse now.
AI is different from "metaverse" in at least one critical aspect: many people are using ChatGPT/AI now, for many different uses, whereas metaverse is still a solution in search of a problem.
[You can also swap "metaverse" out for "crypto/web3" for above.]
Hype is inevitable for any major change, but if you've followed developments on generative AI (not just ChatGPT/Bard), there is real substance behind the furor. Many, many companies/startups are putting resources into this field, and we'll see changes sooner than later (months). These are peole putting their money and livelihood on the line, not just idle talk on online forums.
Tom's HW has its strongpoints, but it is not the place for AI news, nor are most of the popular blogs. If you want to see the scope of AI developments, search on "chatgpt" (it's a good keyword proxy for AI), click News tab, and seek out sites dedicated to AI news. MIT Tech Review, SyncedReview.com are two that comes to mind. Or, you can just ask Bing Chat.
To respond directly to your comment, no, AI isn't just hype that will disappear. In my estimation, it will have as much impact as the advent of the Internet. It's a big deal.
