you need to improve it and not get scared [emphasis mine]

That’s the issue. The median user will get scared. They can’t accurately assess their own competence before they try it, and trying something new is scary. “What if I break something? What if I can’t undo it?” They won’t rely on docs or git pages or man pages or --help (they may not want to touch the CLI at all), because ultimately, that would require them relying on their own understanding thereof.

Impersonal docs, particularly if they’re not written with accessibility for laypeople in mind, can’t replace guides, and a general guide can’t replace specific advice, and none of these can replace the assurance of having a universally helpful support community that will hold their hand if they need it and reliably bail them out if something goes wrong. The median user cannot possibly teach themselves, because they lack the fundamental knowledge and confidence to even assess their level of understanding. You and I, we’re on the tech end of the distribution. We have a basic understanding and mindset. The median user does not.

They can’t trust themselves, so they need someone else to trust. If we want to welcome more people into the FOSS ecosystem in general and Linux in particular, we need to be that someone, and they need to know that they will have that support.

It’s not just about helping them, it’s about the public impression. If they google for assistance and only find threads telling people to RTFM, they’re scared to ask, scared to try even. The learning curve you take for granted, the skill “you need to improve”, looks a lot like a wall from that point of view.

Linux is still perceived as a rather technical thing. We need to cultivate the impression - and the community to back it up - that it’s not actually complicated, and that you’ll readily find people to help you if you take the leap.

Improving tech literacy is an important thing, no doubt, but you can’t get people on board by saying “you have to”. You have to coax them over by promising easy returns on a small investment of time and effort, then let their curiosity lead them further - if they need deeper skills at all.

or you are on the wrong documentation.

Ah yes, because you have the choice of so many different documentations for everything, and all those documentations make sure to point out the others in case you landed on the wrong one for you.

other people are just lazy that thinks the work of a programmer is easy

Doesn’t have to be laziness. If your misconception is shattered, that’s a shock. If they don’t have anyone to ease them through that shock, they’ll do the most natural thing: stay away. If you make it easy to get into, you’ll surely have more success than by walling them off so that only those willing to climb can get into your walled garden.
