Although many share your mindset, I’m glad there are also many that don’t. Otherwise we’d still have countries in a race to keep building up their nuclear weapons for the same exact reasons you just described.
Similarly there have been few positive externalities from nuclear industry, making it easier to make the case to wind down research. This same set of concerns in biotech is much harder to get compliance with, precisely for this reason.
Anyway I’m especially wary of over analogizing to nuclear era concepts: I think they’re a trap.
