  • You need at least two copies in two different places - places that will not burn down/explode/flood/collapse/be locked down by the police at the same time.

    An enterprise is going to be commissioning new computers or reformatting existing ones at least once per day. This means the bitlocker key list would need printouts at least every day in two places.

    Given the above, it’s easy to see that this process will fail from time to time, in ways like accicentally leaking a document with all these keys.









  • Elon sounds like he’s experienced, skilled and is approaching things from a theoretical or ethical or other grand point of view. He used to impress me with his approach on building an electric car company with full self-driving vehicles in the 2010’s. I wasn’t a full believer, but I thought he was competent and wanted Tesla to succeed.

    Then he went and bought Twitter. As a software engineer all my life, and in the startup scene, and having worked in a failed social media platform, I have some experience. Everything he’s said about Twitter is crap and everything he’s done is stupid. And the results speak for themselves.

    I’ve seen people say that Elon sounds great about things they don’t know too much about. But when the topic comes to things they do understand, Elon clearly is wrong.

    He started his career with hundreds of millions of dollars, and he bet it all on a couple of businesses be bought (he was never a founder, always a purchaser).

    Basically he’s been lucky twice (Paypal and Tesla), but each of these won 10-100x on his initial stake.



  • This is exactly the answer.

    I’d just expand on one thing: many systems have multiple apps that need to run at the same time. Each app has its own dependencies, sometimes requiring a specific version of a library.

    In this situation, it’s very easy for one app to need v1 of MyCleverLibrary (and fails with v2) and another needs v2 (and fails with v1). And then at the next OS update, the distro updates to v2.5 and breaks everything.

    In this situation, before containers, you will be stuck, or have some difficult workrounds including different LD_LIBRARY_PATH settings that then break at the next update.

    Using containers, each app has its own libraries at the correct and tested versions. These subtle interdependencies are eliminated and packages ‘just work’.
