I feel like the people I interact with irl don't even know how to boot from a USB. People here probably know how to do some form of coding or at least navigate a directory through the command line. Stg I would bet money on the average person not even being able to create a Lemmy account without assistance.
About the app thing. The other day I had to download from the Google play store. The app you search for is NEVER the first app in the resulting list. The first slot is always sponsor slot. I consider myself quite tech literate and I have accidentally installed that sponsored app because I searched for an app (with very specific search terms) and without thought selected the first. Google is one step away from that trope of the moving X button to close the ad. It's infuriating. Now imagine a tech illiterate trying to get an app.
