High interest in something isn't the same as bubble. Where's the overvalued assets that are out of touch with reality? The guy quoted in the article even referenced Google losing value after the lackluster launch of Bard, which is kind of the opposite of a bubble. The dotcom bubble wasn't a bubble because everyone was talking about the Internet... it was a bubble because companies were severely overvalued for putting literally anything on the web without having functional business models. The businesses were the bubble, not the Internet.
Could AI become a bubble? Possibly. But we're nowhere near anything like that at this point in time. It's just got mindshare, not overvalued assets.
