> When people don't know how the computer actually works, their code is wrong - they get bugs and vulnerabilities they don't understand and can't explain.

While this is true, we're usually targeting a platform, either x86 or arm64, that are incredibly complex pieces of engineering. Unless you are in the IoT or your application requires you to optimize at the hardware level, we're so distant from the hardware when we're programming in python for instance that the level of awareness required about the hardware isn't that much more complicated than the basic Turing machine.
