I mean, do you understand the systems you work on? Down to the ISA? The transistors? The electrons?

The stack gets taller and more complex, as it ever as. People who understand one part of the stack in great depth rarely understand the entire stack. Those who understand its full shape don’t have complete depth at any one part. This is how computing has worked for a few decades at least.

You don’t have to shut up, you’re free to dive in and learn. But you’ll have to balance breadth and depth like the rest of us.
