there are literally millions of people who don’t even know or care about knowing how to change desktop background
I’ll cede “know”, but I heavily dispute “care”.
Plenty of Boomers are painfully aware of how awful the internet has become over the last decade. Hell, they got to experience it before the rest of us precisely because folks who never knew how to migrate off AOL or Yahoo got enshitified first.
My own mom hates using the computer in no small part because she takes too much of what she sees at face value and ends up with tons of spyware, bloat, and scams rampaging across her laptop. I have to clean it out for her every few months, and I’m constantly fighting with her over what’s actually garbage and what she’s convinced she needs.
But the end result is that she just… won’t check her email because she hates it. She won’t answer her phone because she’s afraid of scam callers. She won’t trust ANY website, so she doesn’t use Amazon or Uber or Netflix.
It isn’t that people like my mom don’t care. They care immensely, because modern technology has become unusable for people like her.
