People think he's a tech guy. First and foremost, he is a SALESMAN. Not a tech expert. I read some info on him and he said he failed calculus multiple times and then eventually dropped out of college to do Youtube videos. He doesn't do software development, doesn't know about enterprise tech, and all he does is memorize shit about graphics cards and CPUs. His job is social media production, sales, advertising, video editing, etc. He's not really a STEM guru like people think. He makes tech videos that appeal to mouthbreathers who barely know anything.
At the end of the day, it doesn't matter whether his advice is good or bad, or if what he does is really groundbreaking. All he does is advertise shit you can buy. He makes money off that.
