I really liked RP's "how to position" .pdf, I hope you all have read it. While I am with him on a lot of things (BTC and the big investment), I find it curious sometimes when smart guys get duped. The radiologist comment on that one was one such example [tailwinds]. It is funny that I find in particular areas, even really smart guys often get burned by not knowing what they don't know. I think you all should have a look at this not just due to it being something about radiology, but because it is a great example of digging deeper into what is really going on, not being sold on sexy snake oil (which is modern technology/AI marketing). Have a look.
