I will say that he's of average intelligence, unlike Chris. But that is a low bar to clear.
I think he's a combination of autism, affluence, childhood trauma, and possible early stage schizophrenia. You could replace the trauma and schizophrenia with narcissism and drug abuse. It's not really clear unless we get some IRL reports of him and his past and present.
I do however feel strongly with the information that he is from a wealthy family, that he, in fact, is not a self made genius consulting with CEOs of companies in many industries (which he has claimed for a long time even from his early videos, a claim which he stopped mentioning at least 12 months ago).
I would bet real money that he's on some kind of ongoing trust stipend from his father. What doesn't wash for me is that he built staff around his channel due to his 'success', his videos have been fucking retarded production quality since forever. If he had an editor, the editor would say 'hey you fucking stupid retard, you can't ramble with a wall of text and expect your audience to both listen to you and read your wall of text at the same time', yet his videos since forever have been like this. Who wants to pause mid ramble to read a wall of text? That and his audio quality suddenly changing constantly.
Another user here recently suggested that he records all his dumb thoughts in various locations and stitches them all together at a later point. Which would suggest he's cataloguing his stream of thought. Which would suggest he is completely disorganized with his thoughts.
I think he is getting a monthly allowance from his rich father, and they and him are all fucking insane retarded fucks. This is what has carried him through the last few years. He is not successful, he has no real life experience, if he did half of what he claims to have done he wouldn't be so retarded.
He's a pathetic flabby dumpling.
Winston Churchill at least went to Africa and killed a bunch of cunts before he returned home to become a statesman. The only thing Rudy has killed is his reputation.
