Who do you expect to take effort to change your mind? It is much better to keep most people with skills and grit away by giving off impression that the task is impossible: it means there is more alpha for the ones who actually work with it and make a living. Because whatever alpha there is available, it is negatively correlated with the number of minds and amount of dollars trying to extract it. The markets can only get so efficient. This industry is filled with secrecy on one side, and paradoxically, with a wealth of free information on the other side. It's just that information is so abundant and complex, a normal person has no chance of using it anyway. Especially if they think it's impossible. The hoards of "get-rich-quick" dudes with no emotional control rushing into this thinking they can learn to day-trade in a month, loosing their life savings and then ranting on forums about how it is all just a big casino - they do not help the situation either. Well I guess in a way they do help real managers to keep their jobs. So you keep wondering. Just stay away from the markets :)
