What if all the world ran Linux?

None | Feb. 25, 2011

SAN FRANCISCO, 22 DECEMBER 2010 - There's a cartoon that made the rounds in the Linux community a few years back that I often think of at this time of year.

Slideshow: The Oddest Places to Find Linux

In essence, it depicts a Linux aficionado refusing to help convince someone to switch to Linux, explaining, "If everyone's using it, I'm not cool anymore."

It's a joke, of course, made funny by the fact there may just be the tiniest hint of truth underlying it, at least among some people. The reason I think of it at year's end, though, is that mainstream adoption of Linux is generally considered a goal by many in the free software community, and it's an oft-cited hope for every new year.

There are, of course, numerous critics who say it will never happen, at least on the desktop. I disagree. Either way, however, it's fun to think it through, in both a serious and a not-so-serious way: What if everyone ran Linux?

1. Malware Would Take a Hit

Certainly the biggest effect of widespread Linux adoption would be that today's Windows-dominated monoculture would disappear, replaced instead by a diversity of Linux distributions.

That, in turn, would make life very difficult for malware creators. Sure, they may begin focusing their efforts on Linux rather than Windows, but instead of having one, huge, slow-moving easy target, it would be a matter of trying to kill 100 birds with one stone.

They'd stand very little chance of hitting more than a relatively small proportion of the population at any given time, in other words.

In Linux, the way permissions are assigned also means that the potential damage an individual piece of malware could achieve is much more limited. Would malware creation still be as profitable? I'm not so sure.

2. The PC Security Industry Would Wither

Yes, it's still a good idea to use antivirus software when you're running Linux, and the increased focus on Linux may make that more necessary.

But given Linux's built-in security advantages, what now exists as the colossally huge PC security industry would no longer be able to sustain itself on such a massive scale.

That would be even more true, of course, because of the openness of Linux's code, which enables users to identify and fix vulnerabilities themselves, as they arise. No more waiting for security bulletins or fixes in a "Patch Tuesday" event far down the road.

3. Less Unplanned Downtime
