I love the below article, and recommend you read it.
Essentially it talks about the limits of complexity, and how exotic devices can create exotic problems.
The reason this is relevant is the applicability of this principal to finance.
- Any financial model is only as good as the person or team using it
- Complex strategies can create unforeseen complications
- Some problems have no solution, so you have to choose which form of risk you want to deal with, risk now or risk in the future.
Really good article and I agree with all his points.
