    Hi Kevin,
    I think that you’d do better to respond to Goldin and Wegner’s paper on the Turing Thesis Myth, rather than a (somewhat flippant) statement by Eicher that “One joker restated the Turing Thesis as ‘a computer is defined as a device that can run computer programs.’”
    Your second argument (“except that isn’t what is proposed here”) simply shows that the proposed application of DRM is bad, not that DRM is bad as such.

    Ian, emulators work. Really, they do. The Turing thesis explains why.
    Have a look at the Android SDK – that has an emulation of an ARM processor running a linux kernel running a virtual machine running embedded applications.
    We use emulators every day in computing, because they work to solve real problems.
    That paper is a quibble about the halting problem; you can decompose the computation into a series of algorithmic responses to inputs, and run each one on a Turing machine. If you really want to understand why this is a quibble I suggest you go and read Wolfram’s ‘A New Kind of Science’, which puts forth the theory of computational equivalence in some detail.
    I’ve been blogging about DRM for 6 years now. The companies that relied on it for their businesses have died off, or stopped doing so. I’m still here.
