The logarithmic benefit for exponential cost cure creates a charismatic trap.

In the beginning, you get huge amounts of value for small amounts of effort.

You then commit to that approach, but as you get further you start getting less and less return for more and more effort.

There's never a good time to switch to a bottom-up exponential-value-for-logarithimic-cost curve, so you get stuck.^[xw]
