You sound like you're unfamiliar with public transport?
The way trains usually work nowadays is that you open a website, enter from where to where you want to go, and when you want to arrive, push the "pay" button, and print out the resulting page (which contains your schedule, sometimes a backup schedule, and a QR code that works as your ticket). Then, you just follow the schedule.
There's absolutely no need to know any map or lingo or network.
The main point I'm making is that, for most people, computers are appliances. I use my stove, but I'm not a cook. I'm not a "stove technician", either. I just know that I need to heat stuff at a certain level for a certain amount of time, and I only have to turn a simple knob to achieve that.
Similarly, most computer users aren't programmers or techs. They just want to write a letter. They should be able to do that without knowing about viruses and SSDs and RAM and OS upgrades and file format incompatibilities.
I'm familiar with it, I see people confused everyday, myself too sometimes. It's a nice myth that you can just get somewhere and everything will unfold naturally. You'll always have to learn how to communicate your intent to a system, and for each implementation of this system it will be slightly different, be it a subway network, a word processor, a stove, or even a pencil.
