It's not pedantry. "Digital" says nothing about the physical medium, which is a crucial issue if what you're talking about is the viability of long-term archives. Much better to say "magnetic" or "optical" or what have you, but merely to say "It's the 21st century, we should be digital now!" marks an argument as poorly considered.
