Piponi on Automatic Differentiation

Dan Piponi of Neighborhood of Infinity has written a paper about how he has successfully used automatic differentiation in the movie industry. Unfortunately, in the course of the article he gives the best argument against the use of automatic differentiation I’ve heard:

In this paper we will present one approach to automatic
differentiation and describe one application that was used with considerable success during the post-production of Matrix Reloaded and Revolutions.

I rest my case.
