Do you need years more therapy, or could one conversation resolve the issue?

The author makes the classic misunderstanding of talk therapy, that it is designed to talk about your trauma and go over and over about it. This is false, any modern therapist who practices CBT, ACT, schema therapy, etc. only addresses trauma in the context of how that trauma impacts present decision making. The point isn't to discuss the trauma, it is to discuss how your mind may organize your thoughts in a sub-optimum way caused by your previous experiences.

Ultimately this lack of understanding of modern psychotherapy just makes the entire post sound like snake oil. But I suppose if the author can offer therapeutic snake oil and make money grifting on AI bros, why not.

edit: I just want to follow up, reading through some of the other posts of the author where he describes modern psychology as "poison" and that he refuses to even learn about it. This author really just gives me the exact same vibes as dutchsinse, the quack earthquake prognosticator who claims seismology is a scam, earthquakes are predictable, and that he predicts them by pointing to his custom google earth globes and saying "earthquakes happen there". Of course if he could actually predict earthquakes this would be incredible and the world would change in untold ways since predicting chaos should be impossible. Of course, this never actually happens and ends up being anti-intellectual nonsense.

If the author disagrees with modern ideas the author is welcome to publish their methods and participate in a common discussion like any other scientist studying any other system.

Sounds like a scam.
