France is really serious about it. That is great for the entire EU. Even if most EU countries are still far too complacent, France is currently creating alternatives, doing the hard work, so that alternatives and real world expertise will exist in a few years, when the rest suddenly figures out that the roof is burning.



Both rail and communication infrastructure lead to some useless connections but much of it was no useless, in both cases. GPUs are not bolted to the ground but they do become obsolete no matter if you deny it or not. The issue is that the real costs is in using GPUs is very different from these previous bubbles. Those obsolete GPUs will cause much higher operating costs than newer generations, to the point where they won’t be interesting to use even if you gave them away for free. To make matters worse, other infrastructure is much more flexible in its use, one can transport all sorts of things on railways, one can send all sorts of data on communication infrastructure. Those specialised GPUs aren’t very useful for anything other than a fairly narrow use case.
I think you do not fully appreciate the crazy amounts of GPUs we are talking about here. China has no massive real shortage of GPUs. They managed to get black market GPUs more or less directly from Nvidia just fine. Nor are European universities IT wastelands without compute capabilities. But even if they’d go crazy on expandig compute infrastructure with outdated power hungry GPUs, that would be barely more than a drop in the ocean. Nvidia does have to resort to circular financing to keep the boom cycle accelerating, with GPUs going just to some storage facility if they exist at all. That is not how healthy demand looks like.
