One part of this comes from the fact that some things are really difficult or impossible to repair these days. Cars come with engine computers that you need special tools to access, computers and modern electronics come so integrated that you can't easily swap out components yourself.
The other part is that people treat computers as one entity, not a combination of entities. So the whole device is one item, and if something doesn't work, it's all broken.
To drive a car, people have to learn a shit ton of things, not just about the law, but about the machine itself. And they do, because they have no other choice - and so for most it doesn't even register things could be different.
Look at professional software like Photoshop or AutoCAD - again, everyone knows it's "complicated", and so people either sign up for training courses, or sit down and learn it themselves. Somehow, the software tool being complex isn't a problem. But for most software, we've created an expectation that people should be able to use it from the get-go. I submit that this is wrong. People should be expected to read the manual, like in the old days, and the software should politely force them to.
There are schools and licences for driving a car. There is no EULA for washing clothes.
If we want to train users to not click on "I Agree" to get rid of the legalese then there should be no legalese for installing Spotify or buying from Amazon. I can buy in a shop without needing to sign a 10 page document, so why not the same with Amazon?
We, in tech, have trained users to click on the green buttons to make the computer boxes go away.
