There are two related concepts that have a tendency to get tangled up whenever people talk about the Singularity Institute and advanced AI. These are recursive self-improvement and a hard takeoff (which practically no one is aware of or considers feasible) and Friendly AI (which, in the Asimovian sense, millions of people are aware of and assume it will be important one day).
Recursive self-improvement stems from I.J. Good’s “intelligence explosion” idea. That a very smart mind could make itself smarter, and make itself smarter at being smarter, in an explosive self-improvement cycle, presumably culminating in a godlike entity of immense intelligence and capability. I personally consider this idea highly plausible — look at the relatively small hardware differences between humans and chimps, and tell me that if an entity truly understood the mechanics of intelligence it couldn’t design something another increment above humans — but many people don’t. They presume that when an intelligent mind is put on a substrate a million times faster than biological neurons, it will operate at about the same thinking speed as a human being, because of residual dualistic beliefs about the unrelatedness of a mind and the hardware it runs on. Others probably see human beings as the smartest possible entities that ever will exist. This is anthropocentric vanity.
An accelerated, smarter-than-human, self-modifying mind — that is the essence of an intelligence explosion. Now switch over to Friendly AI.
Friendly AI is an effort to make an AI that is helpful, benevolent, and that we don’t regret making. But it means vastly different things depending on how advanced one believes AI can become in a given time. I assume that the majority of people out there envision that future AIs will look and behave similar to Rosie the Robot in the Jetsons. If so, then AI is not really much of a threat, and the research direction of Friendliness looks unnecessary and premature. This is my theory for why most people don’t care about SIAI’s effort.
The majority of people involved with SIAI believe that the first general AI is likely to be creative and smart enough to find ways to massively improve its own hardware and intelligence, quite quickly. One analogy often given is the rise of humans within the planetary ecosystem — from the perspective of millions of years of slow evolution, we were here in a flash, and remade the face of the Earth in barely any time at all. Some watchers of AI believe that AI could bootstrap itself and gain prominence in timescales considered very short by our own standards. For instance, taking over the world in a matter of weeks or days. One might laugh, but from the perspective of biological evolution, which was the most powerful force on Earth for billions of years, human civilization emerged in what might be considered hours or seconds in “evolution time”. Even an AI a little bit smarter than all humans that have ever lived could come up with a new manufacturing technology it could use to give it all the hardware it needs.
From this perspective, Friendliness gets a little more important. If the first general AI ever created has the potential to become the Earth’s top dog, shouldn’t we care about its motivations and moral beliefs?
Yes. But this is where some people say “if it’s so smart, won’t it throw out whatever goals we give it”? But that’s a topic for another post.
