I don’t think that’s a guide… it’s a hands on class. Maybe even a good idea to pitch to your local community college, community center, or adult edu department.
It’ll shock you how low the average person’s technical literacy is. And since you’re talking about a guide for a lot of things that update independently, the guide will begin to be outdated before you even publish it. It’s exceptionally hard to keep technical documentation in sync with software and hardware that you don’t control, and when the users of your guide hit those spots where the doc doesn’t match, they bail quickly.
What key concepts to cover probably depends on what you’re trying to teach. If it’s just how to use a web browser, the mainstream distros all do that pretty well out of the box once they’re installed (although installation can still a bit of a challenge from one laptop to the next). Maybe the greatest communal benefit would be to teach foundational concepts of online security.
Those are your opinions, not mine. I didn’t offer an opinion on capital punishment. I just pointed out the pretty f’n obvious flaw in your logic.
