In this book I take the view that TDFs are currently still in their larva stage, with challenges that include fiduciary misbehaviors and design flaws, such as one-size-fits-all. Chapters 2 through 5 form the Larva Section of this book which describes the formative deficiencies in TDFs. A TDF is a good idea, but current implementations are nowhere near the high quality they will ultimately become. TDFs are morphing and will eventually overcome their current deficiencies. In the Pupa Section of the book - Chapters 6 through 9 -- I describe these emerging triumphs. Ultimately, Adult TDFs will emerge in all their glory, as I describe in the Conclusion.
