Tegmark’s Book of Foom

Max Tegmark says his new book, Life 3.0, is about what happens when life can design not just its software, as humans have done in Life 2.0, but also its hardware:

Life 1.0 (biological stage) evolves its hardware and software
Life 2.0 (cultural stage) evolves its hardware, designs much of its software
Life 3.0 (technological stage): designs its hardware and software ..
Many AI researchers think that Life 3.0 may arrive during the coming century, perhaps even during our lifetime, spawned by progress in AI. What will happen, and what will this mean for us? That’s the topic of this book. (29-30)

Actually, its not. The book says little about redesigning hardware. While it says interesting things on many topics, its core is on a future “singularity” where AI systems quickly redesign their own software. (A scenario sometimes called “foom”.)

The book starts out with a 19 page fictional “scenario where humans use superintelligence to take over the world.” A small team, apparently seen as unthreatening by the world, somehow knows how to “launch” a “recursive self-improvement” in a system focused on “one particular task: programming AI Systems.” While initially “subhuman”, within five hours it redesigns its software four times and becomes superhuman at its core task, and so “could also teach itself all other humans skills.”

After five more hours and redesigns it can make money by doing half of the tasks at Amazon Mechanical Turk acceptably well. And it does this without having access to vast amounts of hardware or to large datasets of previous performance on such tasks. Within three days it can read and write like humans, and create world class animated movies to make more money. Over the next few months it goes on to take over the news media, education, world opinion, and then the world. It could have taken over much faster, except that its human controllers were careful to maintain control. During this time, no other team on Earth is remotely close to being able to do this.

Tegmark later explains: Continue reading "Tegmark’s Book of Foom" »

Foom Justifies AI Risk Efforts Now

Years ago I was honored to share this blog with Eliezer Yudkowsky. One of his main topics then was AI Risk; he was one of the few people talking about it back then. We debated this topic here, and while we disagreed I felt we made progress in understanding each other and exploring the issues. I assigned a much lower probability than he to his key “foom” scenario.

Recently AI risk has become something of an industry, with far more going on than I can keep track of. Many call working on it one of the most effectively altruistic things one can possibly do. But I’ve searched a bit and as far as I can tell that foom scenario is still the main reason for society to be concerned about AI risk now. Yet there is almost no recent discussion evaluating its likelihood, and certainly nothing that goes into as much depth as did Eliezer and I. Even Bostrom’s book length treatment basically just assumes the scenario. Many seem to think it obvious that if one group lets one AI get out of control, the whole world is at risk. It’s not (obvious).

As I just revisited the topic while revising Age of Em for paperback, let me try to summarize part of my position again here. Continue reading "Foom Justifies AI Risk Efforts Now" »
