Earlier quoted context omitted.
It's crazy how bad the mobile epidemic has gotten. There are kids coming into a Computer Science degree that can't figure out how to unzip a zip or even finding out where files get downloaded to. (Fwiw, those I know dropped out before 2nd year)
At one point, every member of a CS program started without having ever seen or touched a computer. Everyone has to start somewhere. We do not reject new biology majors because they had never touched a microscope before entering the program.
That's like trying to learn a foreign language by picking reading War and Peace in that language, without ever having seen a single translation to that language, or having already read War and Peace in your own. There are a lot of steps you need to take before then.
I would also be pretty surprised if a biology undergrad had never touched a microscope, possibly with the exception of the most impoverished among us. I imagine most people have tried one at some point along the K-12 journey, and there are more introductory treatments of e.g. life science on the way as well.
Starting CS without having "seen or touched" a computer would be like a biology undergrad who wouldn't be able to tell you whether a dog or a tree is a plant or animal.
