Why DRM will win and you can’t do anything to stop it
Eventually your movies will play themselves once and self-destruct and you’ll be left with only the analog hole to get your gay pr0ns. Homomorphic encryption algorithms allow the secret evaluation of arbitrary logical circuits. In short this means that one can compute a useful function without knowing what either the encrypted inputs or outputs are, but whoever holds the decryption key can recover both. You can finally send your data off into the cloud and have it processed securely, or you can write the next Morris worm that no one will be able to fully reverse engineer. Of course, this also means that the next Sony rootkit you install on your computer via your Elton John CD will be invincible to analysis and your debugger will be about as useful as a punch card reader. Future-Stalman is spinning in his future-grave.
