The introduction is a very nice example of how a lot of academic cryptography works and what disconnect there is often between applied and academic cryptography.

They quote Bruce Schneier, basically saying that nobody needs this and we already have plenty of ways to generate secure random numbers. This is countered with some handwavy arguments why you'd need them anyway that aren't really explained.

The truth is: We don't need any theoretical work to generate better random numbers, because we know how to do it. All security problems about random numbers come from the fact that people aren't using the secure random number sources we have.
