I'll add my own opinion which is that he seems to—at least on some level—legitimately believe that all of this is extremely complicated and impossible to understand unless you're someone of his intellectual caliber. It's so complicated, in fact, that even he struggles to keep it all in his head at once. I say this because I otherwise can't come up with any reason why he would continue to give multiple interviews except that the man actually thinks that his ideas were brilliant and sound, but he just made some understandable mistakes and that if people could understand where he's coming from they'd see that he's a sympathetic victim here and not some idiot that was very obviously going to lose everyone's money from the get-go.
Of course the reality is that he's some idiot that was very obviously going to lose everyone's money from the get-go. None of this is very complicated to anyone who's ever worked in finance (admittedly not me). And absolutely fundamental basic controls were never put into place. These controls were skipped because SBF was convinced he was doing something extremely novel and complicated and such old-school concepts would only hinder his ability to execute on his brilliant ideas. Except these ideas weren't all that brilliant, they just involved doing things the likes of which you wouldn't even imagine attempting in traditional finance because… gestures wildly at the ongoing FTX debacle.
