"The future is already here, it's just not evenly distributed" is the Gibson quote that often gets applied to technology, but it applies as well to knowledge in general.

Who is arguing against any of this?

Maybe not anyone at a certain level of academic discourse, but US society and law continue to argue against it: the average person would attempt to make an explicit argument, and laws on the whole reflect an implicit discipline-and-punish philosophy more than the rehab hypothesis.

There's a long way to go before this is democratically-actionable knowledge, and I think he does a good job of presenting some easily-digestible food for thought.
