Yeah, Jesse will often put on a wide-eyed "Wow, I had no idea that martial art X included such-and-such", when I'm quite certain that he knew perfectly well that it did.My guess is, I don’t think Jesse ever thought Tai-Chi was useless. He’s been in Martial Arts for a while and has trained with a lot of good people.
It’s just a little click bait and that’s fine, he’s a businessman. Him posting that video just spreads the word about Tai-Chi and might increase its popularity.
Which I’m also guessing was his plan.
