The vertical integration thing isn’t feasible for anyone besides a giant company that can afford to write its own OS with no outside input. Let’s say I code all my own dependencies in my particular domain (Java). I still have to run my code in an environment: there’s the JVM, then Linux beneath that, the hypervisor at my cloud provider beneath that, etc. You want me to code all of that myself too? You know, frankly I would love to understand and control the stack all the way down. But that’s a life goal. It’s not something most people can or would be interested in doing. We’re all stuck blindly trusting a vast, incomprehensible software supply chain.
