No, the problem is that the built in sources aren’t funky enough ;) In all seriousness, though, yes and guaranteeing that the manufacturing process itself can

No, the problem is that the built in sources aren’t funky enough ;) In all seriousness, though, yes and guaranteeing that the manufacturing process itself can “bake” in the randomness is a super interesting area of research. It’s like 99% of the manufacturing process is an exercise in reducing variability, and then there’s PUFs, where you’re basically trying to maximize variability, but in such a way that you maintain computational precision.
