I've noticed him be wrong about a couple of things. Still has some great stuff to say.

I think looking at his stuff from the early 90s with a 2020 understanding of the occult is still valuable. He goes over tons of topics worth researching for yourself.

I listened to the first 30 or so. I forget... Here are the first 6:

Bill Cooper, Mystery Babylon - Hour 1 - Dawn of Man.

everyone is a liar to a certain extent and when you make a knowledge claim sometimes you will be wrong. i think people should be careful about dismissing people because of their flaws, also because thats a favorite tactic of politicians
