Yes, Unfriendly organizations are a major threat to humanity. The battle is ongoing. The death toll stands in the tens of millions, much higher if you want to count generously. So yes, unfriendly organizations are a real threat. But they're one that we're all aware of. Luckily, a host of Friendly people and organizations are dedicated to fighting them, studying them, and mitigating their damage. And many people end up counteracting them, simply by living generally good lives.

Taking the long view of history, I believe that, over the last few hundred years, we have been winning this battle. There's news of tragedy every day, but by many measures 2012 was the world's best year ever.

The UFAI threat, if the SIAI argument is correct, is a sudden and irreversible threat that is currently ignored even by those attempting to build AGI. That's why a small group of dedicated individuals has chosen it as their best chance to influence the future. They're applying pressure where they believe it can have the greatest effect. No one has claimed that it was the only threat, just a very important one.
