That's academic misconduct. Go start a substack; I'm sure Joe Rogan would love to have you on a guest, and you might even get Netflix to give you a show [2]. Three beautiful avenues available to even the most crackpot individuals; way more profitable, too.

If you walk into a doctor's appointment with a tummy ache, and the doctor says "well, its probably just food poisoning, but wouldn't it be a fun exercise to pretend its stomach cancer?"; be serious, do you believe that is an appropriate way for a doctor to behave? Why would anyone think that any professional in any field, most of all at a respected institution like Harvard, should be held to such low standards of behavior? Discussion and postulation is awesome and fine, but if you can't consider the implications of your authority and the choice of medium, you won't have either for very long.
