If destroying GPUs is the goal, there seem to be a lot simpler, less speculative ways than nanomachines. The semiconductor industry is among the most vulnerable, as the pandemic has shown, with an incredibly long supply chain that mostly consists of a single or a handful of suppliers, defended against sabotage largely by “no one would actually do such a thing”.
Of course that is assuming we don’t have a huge hardware overhang in which case current stockpiles might already be sufficient for doom, or that ASI will be based heavily on GPU computing at all.
