Trying to make bits uncopyable is like trying to make water not wet. The sooner people accept this, and build business models that take this into account, the sooner people will start making money again.

History has taught us: never underestimate the amount of money, time, and effort someone will expend to thwart a security system. It's always better to assume the worst. Assume your adversaries are better than they are. Assume science and technology will soon be able to do things they cannot yet. Give yourself a margin for error. Give yourself more security than you need today. When the unexpected happens, you'll be glad you did.
