Linus of LTT is an ascended videogamer. His knowledge ends just past overclocking your watercooled setup to get 2 more FPS out of the latest videogame. He's sometimes entertaining but never informative.
His jokes are not even that funny. The amount of followers he has is insane.
There are only so maany ways you can overclock/mod a build or "accidentally" drop expensive computer parts.
I disagree with you on Linus though. He is still a very reliable source when it comes to product reviews, and his channel is informative when it comes to which part to pick. He realizes that the channel is not very technical, which is why he is investing heavily into equipping and staffing his new test lab.
