Chalk lines on the pavement

I don’t think this article ("Ye cannae change the laws of physics!") provides any new insights, but it uses some nice images:

Trying to make Digital Rights Management (DRM) work in the real world is like asking engineers to do "Star Trek" style magic, rather than real engineering. DRM simply cannot work. (…)

Engineers know that DRM doesn’t work, that it can’t possibly work. Yet just like Scotty when Captain Kirk calls from the bridge asking for the impossible they can’t seem to help producing ever more complicated versions of the same broken system. (…)

Claiming that this process can ever be made secure from the people you’ve just given all this information to is like believing you can create a secure bank vault by drawing chalk lines on the pavement, piling the money inside and asking customers to "respect these boundaries".
