Not just “some robots or nanomachines” but “enough robots or nanomachines to maintain existing chip fabs, and also the supply chains (e.g. for ultra-pure water and silicon) which feed into those chip fabs, or make its own high-performance computing hardware”.
My guess is software performance will be enough to not really have to make many more chips until you are at a quite advanced tech level where making better chips is easy. But it’s something one should actually think carefully about, and there is a bit of hope in that it would become a blocker, but it doesn’t seem that likely to me.
