He's a decent indication for the political climate in the idk what to call them, I guess, Leftist spaces with Anti-Capitalist sentiment. His goals seem to be to grow as much as possible, while maintaining a outwards facing anti-imperialist persona. It's most likely genuine.
His main flaws, from what I've seen, is he's not well educated on Marxism besides the foundational texts and whatever he watches on stream or learns from his friends. But then again I'm not in his position idk how much room he has to move. From what I've heard of him he wants to serve as an entry point for the lumpenproletariat Americans who then get radicalized further.
Of course the elephant in the room here and the big question is: Who is this 3rd space people are supposed to be moving towards in the radicalization pipeline? PSL? All of this radicalization will have been for naught when a populist can just sweep up the chaos, with appealing messages.
