Overconfidence leads to downfall

I know how this guy is a blessing in disguise for all those students who can't afford quality education blah blah blah, but isn't he going mentally berserk these days? If you see his WhatsApp channel the way he boast about himself is pretty disrespectful to other teachers. He is a good teacher no doubt but if you follow him recently he's seems more interested to be a social media clown than a teacher ig. For example just see this post he literally wrote "na kisi teacher ke notes mein" like dude 😭 the next picture I attached is from pj sir's 8th Jun class . He teaches that sh!t every year and not only hjm but most teachers teach that who are good. But these guy literally seems to have gone berserk in claiming everything that comes in exam are only from MR's notes. Like dude the original people who have studied from kota 5-6 yrs prior to this ed tech doom even know that the concept of MR star is copied from a top physical chemistry faculty. I used to like this guy and even took few classes of him, but he seems to go rogue day by day.
