I don’t think that’s what they’re saying at all; it’s not that it hasn’t been done, it’s that no one’s found a practical way to do it at scale and make pig milk (pilk?) a viable product

Yeah, I wasn’t thinking of the code being proprietary, but the data. One of my friends is a nuclear engineer, and as an undergraduate student she had to pass a background check before the DoE would mail her a DVD containing high-accuracy data on measurements of nuclear material, because that’s not shared publicly. Not my background, so I don’t know precisely what the measurements were, but I imagine data on weapons grade materials is protected more thoroughly than the reactor tech she was working with.

Goes with the rest - precise simulations of nuclear material are often highly classified. Sometimes also things like “simulating the spread of a bio weapon attack, using AT&Ts cell tower data to get high precision info about population density across an entire city.”

SpotShotter? Technically yes, but it works terribly. Even the Wikipedia articles second sentence reads “researchers have noted concerns about effectiveness, reliability, privacy, and equity [of ShotSpotter]”
