My own experience, as someone who is not necessarily tech illiterate, but also not an expert either:

I decided to check out some basic Linux stuff, and found a post directing newcomers to a website that was supposed to be a top-notch beginner’s guide. This guide started with a history of Linux, written in the style of an early 2000s GameFAQs guide. It then jumped immediately into selecting a distro, and started describing each option with terms like "lightweight"and “robust” without explaining what those terms meant in that context - or even defining what a distro was in the first place.

As someone who has used Windows for around 3 decades, I could make some inferences to fill in the gaps. But I imagine someone with less experience with PCs would get completely lost.

Now on the flip side, I’ve also shared in another thread the story of how I lost interest in programming partway through my introductory university course, and mostly received positive feedback. The folks in that thread seemed happy to hear the perspective of an outsider.
