In terms of using the cord I guess I am the minority
I think you’re probably in the majority, just maybe not people you run into on Lemmy.
I personally don’t have any family members who ever transfer data with a cable from their phone that I know of. Even at work, I would say only a minority do (although the age demographic is skewed older, so just understanding the phone itself is a big deal).
Also if you google number of people who use physical connectors to backup data, you get a flood of results asking if it’s even possible lol
