Singularity objections: Singularity and intelligence

2008-01-29 · ~1,500 words

A companion piece to the SIAI-objections section, also posted to the SL4 list. Alyssa, then 16, was assembling a wiki-style catalogue of objections to the Singularity Institute’s research agenda along with draft rebuttals. This installment covers the “intelligence isn’t everything” family of objections, the question of whether an intelligence explosion is bounded by physical constraints, and definitional pushback on what “intelligence” even means. Inline annotations from Alyssa (“Tom”) and Kaj Sotala are preserved.


Intelligence isn’t everything An AI still wouldn’t have the resources of humanity.

Looking at early humans, one wouldn’t have expected them to rise to a dominant position based on their nearly nonexistent resources and only a mental advantage over their environment. All advantages that had so far been developed had been built-in ones — poison spikes, sharp teeth, acute hearing — while humans had no extraordinary physical capabilities. There was no reason to assume that a simple intellect would help them out as much as it did.

When discussing the threat of an advanced AI, it has at its disposal a mental advantage over its environment and easy access to all the resources it can hack, con or persuade its way to — potentially a lot, given that humans are easy to manipulate. If an outside observer couldn’t have predicted the rise of humanity based on the information available so far, and we are capable of coming up with plenty of ways that an AI could rise into a position of power… how many ways must there be for a superintelligent being to do so, that we aren’t capable of even imagining?

Bacteria and insects are more numerous than humans.

Possible rebuttals: Sheer population size isn’t a reasonable measure of success. We wouldn’t consider it a success if the Earth was so jam-packed with humans that there was barely enough food. Indeed, overpopulation is already considered a serious problem in many countries, particularly in non-industrialized nations where birth control isn’t readily available.

Bacteria and insects took hundreds of millions of years to grow and adapt to the huge range of environments they currently inhabit. Modern man has been around for less than .1% of that timespan, yet we have increased our numbers faster than any other species in history.

Bacteria, insects, fungi, protists, and other small organisms have always existed in much larger numbers than mammals, regardless of how successful the mammals were, primarily because of size.

Organisms with short life cycles reproduce much faster than organisms with long cycles (r-strategy vs. K-strategy). If the human race had reproduced faster, people would die much faster than they do now.

Superminds won’t be solving The Meaning Of Life or breaking the laws of physics.

Rebuttal synopsis: The Meaning Of Life has already been solved. As for the laws of physics, we can far exceed the bounds of today’s civilization without breaking any of them. There’s no physical law saying humans have to get cancer or travel at .00001% of c.

Just because you can think a million times faster doesn’t mean you can do experiments a million times faster; super AI will not invent super nanotech three hours after it awakens.

Rebuttal synopsis: All of the world’s major laboratories are now computerized, and computers aren’t secure from human hackers, much less superintelligent AIs.

Machines will never be placed in positions of power.

(Kurzweil paraphrase): If, tomorrow, all the computers in the world shut down, the entire planet would be thrown into utter chaos. Basic utilities like electricity, cable, phone, etc. would all fail. Most cars wouldn’t even start. You couldn’t get paid, or use a credit card, or take money out of a bank. The trillions of dollars transferred globally on a daily basis would come to a screeching halt. The government and the military would be crippled, unable to communicate or take action. All investments, from stocks, to bonds, to mutual funds, would suddenly disappear. And on and on it goes…

On an intelligence explosion There are limits to everything. You can’t get infinite growth.

For one, this is mainly an objection against the Accelerating Change interpretation of the Singularity, most famously advanced by Ray Kurzweil. When talking about the Singularity, many people are in fact referring to the “Intelligence Explosion” or “Event Horizon” interpretations, which are the ones this article is mainly concerned with. Neither of these requires infinite growth — they only require us to be able to create minds which are smarter than humans. Secondly, even Kurzweil’s interpretation doesn’t contain infinite anything — “there are limits, but they are not very limiting”, is what he has been quoted saying.

Infinite growth isn’t necessary; the potential for finite growth is enormous. Even right here on Earth, there’s 6 × 10^24 kg of available matter; almost none of it has ever been used for anything.

A smarter being is also more complex, and thus cannot necessarily improve itself any faster than the previous stage — no exponential spiral.

Does anyone have counter-evidence? This looks like a real possibility. — Alyssa Computation takes power. Fast super AI will probably draw red-hot power for questionable benefit. (Also, so far fast serial computation takes far more power than slow parallel computation, like brains.)

Rebuttal synopsis: Power consumption per FLOP has gone down with Moore’s Law like every other parameter, and there’s no reason to believe this trend will stop. Human brains only consume about 1% of the power currently used by human civilization.

Giant computers and super AI can be obedient tools as easily as they can be free-willed rogues, so there’s no reason to think humans + loyal AI will be upstaged by rogues. The bigger the complex intelligence, the less it matters that one part of the complex intelligence is a slow meat-brain.

I don’t understand this objection. — Alyssa It’s basically saying that AI can be used for good as well as bad, and there’s no reason to assume that the bad designs will beat the good ones. Might be useful to say something about a first-mover advantage, as well as about the fact that it’s incredibly hard to get right a mind design whose wishes are anywhere near what humans would want them to be… — Kaj Biology gives us no reason to believe in hard transitions or steep levels of intelligence. Computer science does, but puts the Singularity as having happened back when language was developed.

Rebuttal synopsis: The average human has a frontal cortex only around six times larger than the average chimpanzee, and yet the result of that change has been huge (civilization, nuclear bombs, etc.).

Strong Drexlerian nanotech seems to be bunk in the mind of most chemists, and there’s no reason to think AI have any trump advantage with regard to it.

Rebuttal synopsis: Nanosystems , Eric Drexler’s 1992 technical book on nanotechnology, has never been found to contain a significant error.

There is a fundamental limit on intelligence, somewhere close to or only slightly above the human level.

It seems that counter-evidence exists, but I haven’t seen it. — Alyssa One could note that simply making faster processors or larger stores of memory will make a mind more intelligent, and that our brains are nowhere near the physical limits for either. — Kaj On intelligence You can’t build a superintelligent machine when we can’t even define what intelligence means.

Rebuttal synopsis: Even if we can’t define intelligence precisely yet, in practical terms, we know what it does: intelligence provides optimization power to reshape the world. There are plenty of things that could give one more optimization power, for instance, faster processing and more memory.

Intelligence is not linear or one-dimensional, so talking about greater- or below-human intelligences doesn’t make sense.

Talking about human-equivalent AI is pointless. A computer mind would of necessity be much smarter than humans in some fields: for instance, in the field of doing multiplication or addition. Creating a truly “human-equivalent” AI would require needless work and involve essentially crippling the AI.

It is true that intelligence is hard to measure with a single, linear variable. It is also true that it will probably take a long time before there is truly human-equivalent AI, just as there is no bird-level flight: humans will have their own strong sides, while AIs will have their own strong sides. A simple calculator is already superintelligent, if speed of multiplication is the only thing being measured.

However, there are such things as rough human-equivalence and rough below-human equivalence. No human adult has exactly the same capabilities, yet we still speak of adult-level intelligence. A calculator might be superintelligent in a single field, but obviously no manager would hire a calculator to be trained as an accountant, nor would he hire a monkey. A “human-level intelligence” simply means a mind that is roughly capable of learning and carrying out the things that humans are capable of learning and doing. It does not mean that we’d be aiming to build an AI with exactly the same capabilities as a human mind. Likewise, a “superhuman intelligence” is a mind that can do all the things humans can at least at a roughly equivalent level, as well as being considerably better in many of them.
