         <p>In our digital lives, the situation is quite different: All of our activities typically happen on a single device. This causes us to worry about whether it's safe to click on a link or install an app.</p>
         <p>Qubes removes this worry by allowing us to divide a device into many compartments, much like we divide a physical building into many rooms. Better yet, it allows us to create new compartments whenever we need them and gives us sophisticated tools for using them for different activites and in concert with one another.</p>

         <p>Many of us are initially surprised to learn that our devices do not support the kind of secure compartmentalization that our lives demand, and we're disappointed that software vendors rely on generic defenses that repeatedly succumb to new attacks.</p>
-        <p>In building Qubes, our working assumption is that all software contains bugs. Not only that, but in their stampeding rush to meet deadlines, the world's stressed-out software developers are pumping out new code at a staggering rate &mdash; far faster than the comparatively smaller population of security experts could ever hope to analyse it for vulnerabilities, much less fix everything. Rather than pretend that we can prevent these inevitable vulnerabilities from being exploited, we've designed Qubes under the assumption that they <em>will</em> be exploited. It's only a matter of time until the next zero-day attack.</p>

         <p>In light of this sobering reality, Qubes takes an eminently practical approach: confine, control, and contain the damage. It allows you to keep valuable data separate from risky activities, preventing cross-contamination. This means you you can do everything on the same physical computer without having to worry about a single successful cyberattack taking down your entire digital life in one fell swoop. In fact, Qubes has <a href="https://invisiblethingslab.com/resources/2014/Software_compartmentalization_vs_physical_separation.pdf">distinct advantages over physical air gaps</a>.</p>
