Even if you know how the compiler and OS constructs work, you might not know how the hardware circuits work. Even if you know circuits work, you might not know how the power generation or cooling work. Even if you know how the power generation works, you don't know how extracting natural gas works or solar panels are created. etc,etc

My takeaway is that modern system complexity can only be achieved via advanced specialization and trade. No one human brain can master all of the complexity needed for the wonders of modern tech. So we need to figure out how to cooperate if we want to continue to advance technology.
