    The thing with random internet replies: you never know if it’s true (you could look it up, but that would make life to easy).

    So this is or:

    • really scary
    • unbelievable smart cause nobody knows how to use them
    • not true

    Probably there are some other options but I’ll go for a combination of the first and second one and hoping for the third

      It was true at one point, but has since changed. The systems are totally air-gapped and worked 100% of the time, so there was never a reason to change them.

      Also true: Boeing still uses floppies to update their 747s.

            yea but SSDs are not reliable enough. random bit flips from cosmic events, degradation of data if unpowered for a long time, can only be written to so many times

            they are VERY reliable for casual PC use or even server storage but not for something that could start ww3 if it glitches

            also, as some other people said, dont change something that already works

              That has nothing to do with file transfer (“updating”), just long term storage. It’s also a solved problem. You can solve it at the software level with modern self-healing filesystems.
