The problem policymakers are faced with is:<p>* Everyone is going to use encryption by default, without trying or even knowing what cryptography is.<p>* That cryptography is going to be unbreakable, not just by today&#x27;s investigators but possibly for millennia. Even if quantum attacks on crypto are possible, we have ciphers that will hold up, and computers are already small and fast enough to make their added expense a rounding error.<p>This is a very different situation than the Barksdale crew using a keypad code. 70 years ago, military grade crypto was crackable (and doing so helped us win World War 2). That isn&#x27;t going to happen in 70 years, ever again.
