I have an acquaintance like this I've distanced from. Reels out a load of nonsense based on watching YT clips.
Like most of these YT "gurus" he doesn't do much with his life at all so he's plenty of time to chill, going further down the YouTube rabbit hole. 5g, The Royals, Covid-19 is a hoax blah blah blah.
Basic local job. Doesn't travel much, not even outside London much less abroad. Doesn't study or have hobbies but knows more than scientists, professors etc just like that.
Yet this do-nothing go-nowhere man now loftily believes himself to be learned, special, and that we are all sheep who need to "Do The Research!!" If we don't agree with all that he says.
ie follow his way of spending hours daily on YouTube becoming a follower of randoms and spouting their views. I think he's going to change the world from the comfort of his chair (lazy - they never want to actually get up and do much) by alienating family and friends, just moaning at people via the internet really. Google & YT have consumed them.
I've no faith in this government and 1 or 2 theories may hold some truth, I think. But I'm not self-absorbed enough to chat my way or the highway bullshit and condemn people as sheep on the one hand, yet on the other it's ok for them to be the kind of sheep that is obsessed by the utterings of some bloke who's stuck a camera in his face and filmed himself for YouTube.
These University of Life, School of Hard Knocks people are aimless, craving a way to feel special, validated, that they matter above most. & In YouTube/social media they've found it. In their own heads, at least.
