I don't think this is fair to say. Could be said for the generation after me. Maybe not. I think this kind of sweeping generalisation is not fair on any generation though. There are motivated and lazy people in all generations, as there are people with good/bad attention spans.
And what you've said about YouTube might be true, but it wasn't for me. I did not go to YouTube for the community aspect, but only because like I said before I didn't even know that the Arch wiki was an install guide as well.
