This claim is mathematically nonsensical. It implies a more-or-less linear relationship, that more is always better. But there's no reason to limit that to H100s. Conventional servers are, if anything, rather more established in their ability to generate value, by which I mean, however much potential AI servers may have to be more important than conventional servers that they may manifest in the future, we know how to use conventional servers to generate value now.

And thus, by this logic, every company in the world should just be buying as many servers as they can get their hands on, because More Servers = More Value.

Obviously, this is not happening. It doesn't take much analysis to start listing the many and manifold reasons why. Many of those reasons will apply to GPUs as well. Just as if everything in AWS got 10x faster, overnight, this would not create a situation where everyone suddenly starts grabbing more servers in AWS. Obviously everyone would start trimming down, even if perhaps in a few years time they'd find some way to use this burst of power such that they can use more later. This can't happen overnight, though. It would take time, and not "weeks" or "months" but "years" at scale.

Incorporating the important variable of time in the analysis, if AIs become literally hundreds of times cheaper to run, today, then it is perfectly logical that the near-term demand for the hardware to run them is also going to go way, way down. However much potential AI may have, it is fairly clear looking out at the AI landscape right now that there isn't really anyone out there unlocking vast amounts of value and sitting there wringing their hands because they just can't get more GPU compute. The GPU rush has been from fear that someone will figure out how to "really" unlock AI and then they'll be stuck without the hardware to compete.

It may be the case that vastly cheaper AI will in fact be part of unlocking that value, and that as the AI industry grows it will grow faster as a result... but that's still going to be on a multi-year time frame, not a tomorrow time frame. And all those GPUs and all those valuations are still broadly based on them being valuable real soon now, not in a few years, and all those GPU purchases are on the assumption they need them now, or on a timeframe where we can't be waiting around, rather than waiting for some rounds of exponential doublings to bring price down. The hardware curve in 5 years may be higher but the curve in the next year would be lower, and by a lot.

And, you know, who's to say we're done? I doubt there's another 100x in there, but is someone going to eke out another 2x improvement? Or a 10x improvement? Making it easier to run lots of experiments makes it much more likely for that to happen. I'm skeptical of another 10x general improvement but 10x improvements for specific, important use cases I can't rule out.

Edit: I should also point out this is an extremely common pattern in technology in general. Often the very hardest part is producing a thing that does a particular task at all. Once we have it in hand, once we can use it and learn how it operates and what its characteristic operating modes are, once we can try modifications to it in the real world and see what happens, optimizing it becomes much easier, sometimes explosively so by comparison. Taking any first iteration of a tech that is practical and then trying to straight-line demand based on it is silly, in all sorts of ways and all directions. The internal combustion engine, for example, has had a myriad of impacts on the world and certainly after various improvements many, many millions if not billions of them have been made... but any company that reacted to the first couple of cars and just went ballistic buying those first-generation internal combustion engines would have lost everything, and rather quickly.
