&gt; - Servo: How many years do they need to build a new browser with the experience they already have?<p>Browsers are <i>big</i>. There&#x27;s not really been a from-scratch browser written since the 90s, so there&#x27;s not really any comparison point as to how long it takes.<p>It&#x27;s also worthwhile remembering that Gecko has over ten times the number of developers that Servo does—yet Servo has to catch up with much of what Gecko has done to it!<p>Servo is certainly getting there (and honestly, the progress that&#x27;s been made is incredibly impressive, both in terms of the man-hours involved per-feature and in absolute progress: many features are being implemented far quicker than they were in other browsers), and it seems plausible that this time next year there could be something relatively usable.
