That's a great philosophy.
Ok, let's take an organization, let's call them, say Ammizzun. Totally not Amazon. Let's say you have a very aggressive hire/fire policy which worked really well in rapid scaling and growth of your company. Now you have a million odd customers highly dependent on systems that were built by people that are now one? two? three? four? hire/fire generations up-or-out or cashed-out cycles ago.
So.... who owns it if the people that wrote it are lllloooooonnnnggg gone? Like, not just long gone one or two cycles ago so some institutional memory exists. I mean, GONE.
