Maybe it would be better to say that describing a person as ignorant without a scope rarely makes sense.

I mean I've worked with literal rocket scientists that can't figure out how to attach a PDF to an email. I would have a hard time describing them as 'dumb'. And don't even get me started on trying to help doctors and surgeons when I worked in medical.

Just because we might find something easy or 'intuitive' after spending most of our lives in front of computer doesn't mean it's actually easy.
