I was interviewed for, and quoted in, this ISACA publication around Smart Contracts.
Upon reflection, what we are really seeing is just a continuation of the concept of Code = Law as pointed out by Lawrence Lessig in his 1999 book, Code and Other Law of Cyberspace.
The Smart Contracts doc is a free download (after registration) and can be found here:
