hm... good possible counterpoint.
tho maybe different these days with the Internet and speed/availability of communication from/to everyone?

Maybe, but my understanding of how the Manhattan Project kept its secrecy was mainly through incentivization and compartmentalization. Basically everyone worked in small silos, unaware of what other groups were doing, and the risk/reward structure made keeping the secret an easy decision. Only a relatively small group had the whole picture and knew what they were really doing. From my perspective, the internet hasn’t made that strategy any less effective. If anything, it makes it easier to obfuscate with information overload.
