Sure, but you have to consider Carl Sagan's point, "The fact that some geniuses were laughed at does not imply that all who are laughed at are geniuses. They laughed at Columbus, they laughed at Fulton, they laughed at the Wright brothers. But they also laughed at Bozo the Clown." Some truly useful technologies start out slow and the question is asked if they are fads or bubbles even though they end up having huge impact. But plenty of things that at first appeared to be fads or bubbles truly were fads or bubbles.
Personally I think AI is unlikely to go the way of NFTs and it shows actual promise. What I'm much less convinced of is that it will prove valuable in a way that's even remotely within the same order of magnitude as the investments being pumped into it. The Internet didn't begin as a massive black hole sucking all the light out of the room for anything else before it really started showing commensurate ROI.
Columbus was not a genius. He was an idiot who believed the earth was smaller than the scientists of his day, and the scientists were right. Columbus became successful through pure luck, genocide and cruelty.
Most idiots like Columbus died in obscurity.

I think there are two layers of uncertainty here. One is, as you say, if the value is worth the investment. The other and possibly bigger issue is who is going to capture the value and how.
Assuming AI turns out to be wildly valuable, I'm not at all convinced that at the end of this money spending race that the companies pouring many billions of dollars into commercial LLMs are going to end up notably ahead of open models that are running the race on the cheap by drafting behind the "frontier" models.
For now the frontier models can stay ahead by burning heaps of money but if/when progress slows toward a limit whatever lead they have is going to quickly evaporate.
At some point I suspect some ugly legal battles as some attempt to construct some sort of moat that doesn't automatically drain after a few months of slowed progress. Google's recent complaining about people distilling gemini could be an early signal of this.
I have no idea how any of that would shake out legally, but I have a hard time sympathizing with commercial LLM providers (who slurped up most existing human knowledge without permission) if/when they start to get upset about people ripping them off.
Even that you mentioned NFTs in comparison hurts my mind
All those racks of Nvidia machines might not pay off for the companies buying them, but I have a hard time believing that people are still questioning the utility of this stuff. In the last hour, Opus downloaded data for and implemented a couple of APIs that I would’ve otherwise paid hundreds a month for, end to end, from research all the way to testing its implementation. It’s so, incredibly, obviously useful.
