I don't particularly like the OTO because of the distortion of Enlightenment Era groups and Freemasonry. Crowley and some of the esoteric philosophies are interesting but there's not many concrete ideas there.
John Fleming wrote a great book related to this called The Dark Side of the Enlightenment: Wizards, Alchemists, and Spiritual Seekers in the Age of Reason.
There's a distinction between Freemasonry, philosophy, and DMT; and the speculative ideas of John Dee, the OTO and mystical reasoning. A lot of the most fascinating things are polluted with ridiculous claims and beliefs.
I was not aware of all the controversy. I just happen to watch PBS. But I've come to realize that I shouldn't lead with the potential worst aspects of people. Or qualify everyone I like with "but I don't agree with X". It's burdensome.
His point is to not have an overly specific plan, rather have a system where you are constantly learning things and meeting people that will be helpful to you in the future. He's also a former computer programmer and has a startup for easily sharing schedules among groups.
