If Elon Musk has a tragic flaw, it isn’t his temper, or his treatment of underlings, or his refusal to follow securities laws. Musk’s tragic flaw is his inability to accept that he’s extremely, painfully unfunny. At best, his brand of humor resembles dad jokes from the dad who thinks he can hang, as when he hosted Saturday Night Live, tried to start an Onion competitor, or sold novelty blowtorches for no good reason. At other times, the gags aren’t just whiffs; they’re also stunningly self-destructive.
