I always assume, unfortunately, that once companies start to get to a certain point they become strategic, and military applications comes into play. They then probably get special consideration when it comes to funding and access. All of Musk's efforts certainly fit this paradigm.
Google "atoms for peace." You will find an entire multidimensional cluster of hype ranging from Rickover maneuvering to get a nuclear navy, which seems to work pretty well, but on the way there it created a subsidized nuclear reactor business which was never in the money but for subsidies, loss leaders, and underbids. There was no Golden Age of nuclear power. There were fixed bid contracts that masked cost overruns until they didn't anymore. There was FOMO about Soviet gigantism and (subsidized) European nuclear projects.
