Looking to the future, we can switch to quantum-resistant ciphers and go on with our lives.&lt;p&gt;But the past? Mass decryption of archived communication would lead to learning things we never wanted to know. It would cause economic ruin, social turmoil, and worse on a huge scale. And it may now be inevitable. Everyone has secrets.&lt;p&gt;We should start moving toward quantum-resistant cryptography &lt;i&gt;now&lt;/i&gt; so that by the time these machines become practical, sensitive information will have fallen out of most archives.</text></comment>
