Well, Linus is the guy who was repairing things by "reflowing" them with a hot air gun from a hardware store, among other things.
Until certain Louis Rossmann took him to task over this, in a fairly viral expletive-laden rant video. It ended up by Linus actually visiting Louis, conceding he had no clue what he was doing there (kudos for that) and that replacing/fixing a BGA chip is a taaad more tricky than what his "guide" with the heatgun suggested.
He has (waay) more money than actual technical knowledge/skill, sadly. As said by others, it is a pure clickbaity entertainment produced professionally with a large crew and budget, aimed straight at "gamers" who don't know better and who are the target group for his sponsors. He is a very good businessman milking that particular "influencer marketing" cash cow, though.
What Linus produces is a stream of stuff to keep Youtube algorithm happy, nothing more. He actually admitted some time ago that he had some major personal issues because it is a very stressful job after a while - finding material to film, produce the footage, get it edited, published, etc. Plus all the paperwork, sponsors and so on. And this a week after week because bills and salaries have to be paid.
He runs a fairly sizeable media production company (
https://linusmediagroup.com/our-team - almost 60 people!) to produce the content for his channels (he has several + podcasts, etc.) - and in every episode he is personally involved. I wouldn't want a "life" like that.
If you want actually meaningful technical content, go elsewhere.
