As an older person, I find this observation very interesting.
Today, I would consider people in general to be much more technically knowledgeable compared to people 20+ years ago. And yet, 20 years ago, removable storage was quite common, and probably expected of most devices.
I'm pretty technical (As is nearly everyone on HN), and I have no idea where my photos are stored on my Android's file system. I have no idea where the APKs are for all my installed apps, or where their saved data sits.
Very few people know how apps actually store files on a mobile device and as people increasingly use phones / tablets instead of PCs their knowledge of PC file systems reduces. So for many people, copying photos from a phone (or cloud backup) to a computer could be quite a challenge.
BTW IDK why there are two names for the same concept
Disclaimer: I'm also an older person.
People are more capable but security like this needs to just be a part of the usual workflow or problems will continue to occur.
Moving files around on a device, extra steps, just doesn't work for the masses.
Admittedly, the technological world is nearly impossible to avoid exposure to these days, where it was entirely optional (or downright prohibitive) to be involved with in the past.
So in general, thank you older people for creating them, I have a lot of fun with them.
I had an 11 year old ask me what "right-click" was the other day. Yes, it sounds insane and it absolutely is. I blame the public school system.
They know only what they're exposed to, and no more.
Most devices don't have SD cards these days.
