Allegedly, the worst enemies of investors are - themselves. Humans are too emotional, sometimes they seek to avoid defeats instead of to reach goals or success. Machines can be superior in many cases. But they are still not humans. I think creativity is what AI doesn't have.

And emotions, passion. What is a disadvantage in many decisions, can be an advantage in other cases. Like creativity, arts, philosophy, other sciences. The same thing what makes us erroneous and vulnerable, makes us also successful and adaptive, progressive, developing. Human.
