That's fine but when people use technology every day, their phones, computers, ect.. and not know what a web browser is that's a whole different level of ignorance. Not just computing tho also cars. I barely know much about cars but I understand the idea of an engine, like you said it's okay to know enough. If something breaks on my car I look it up on YouTube and learn a little more slowly. Some people tho will drive a car everyday for their entire life and not understand what a piston even is.
