Having a general understanding of how computer hardware and software works, how it’s built, and how it’s assembled is not the same thing as “fully understanding.” If you truly did fully understand, you’d be making a killing securing the OS and application stack, and the world would have far better software. That we still have constant issues with our hardware and software proves that you do not “fully understand” it.

What do you fully understand then? Because you absolutely don't understand your own toilet by this metric.
