For many people, it seems to be.

There are plenty of people trying to write code who don't even under
the concept of different bases.

I remember trying to explain the concept of CPU registers, stacks,
interrupts, and binary representations to VAX/VMS FORTRAN programmers
and getting absolutely nowhere.

Years later, I went through the same exercise with a bunch of Windows
C++ programmers, and they seemed similarly baffled.

Perhaps I was just a bad teacher.
