you don't need to understand them
Part of the problem is that there are a lotof people who not only don't understand, they don't want to, and will actively try to avoid it, even if it's required for their job. I have a coworker who will actively sabotage her tasks that involve even basic office use because she hates tech. Just yesterday she managed to lock herself permanently out of her apple account and lost EVERYTHING because she refused to do any kind of setup to make sure she knew her passwords or had her shit backed up. Years of stuff gone.
There's a lot of people out there like that.
