Here’s Thierer’s bottom line:

Luckily for us, Lessig’s lugubrious predictions proved largely unwarranted. Code has not become the great regulator of markets or enslaver of man; it has been a liberator of both. Indeed, the story of the past digital decade has been the exact opposite of the one Lessig envisioned in Code. Cyberspace has proven far more difficult to “control” or regulate than any of us ever imagined. More importantly, the volume and pace of technological innovation we have witnessed over the past decade has been nothing short of stunning.

Had there been anything to the Lessig’s “code-is-law” theory, AOL’s walled-garden model would still be the dominant web paradigm instead of search, social networking, blogs, and wikis. Instead, AOL — a company Lessig spent a great deal of time fretting over in Code — was forced to tear down those walls years ago in an effort to retain customers, and now Time Warner isspinning it off entirely. Not only are walled gardens dead, but just about every proprietary digital system is quickly cracked open and modified or challenged by open source and free-to-the-world Web 2.0 alternatives. How can this be the case if, as Lessig predicted, unregulated code creates a world of “perfect control”?
