If you make investment decisions based on podcast called all-in then yes you should not watch it. It is a entertainment/ news podcast, treat it as such.
No, it's actually a bad idea to expose your brain to pathologically dishonest people.
They make mistake and they also come out and apologize or call it out when they are wrong. No one is 100% correct all the time. You have never made mistake or said something wrong when having discussion with your friends ? They are not running this as a educational channel , its a podcast where 4 friends chit chat.
