What if artificial intelligence ever becomes sentient?

Bloomberg Opinion columnist, Tyler Cowen explores the implications….


Blake Lemoine, a senior software engineer in Google’s Responsible AI organisation, recently made claims that one of the company’s products was a sentient being with consciousness and a soul. Field experts have not backed him up, and Google has placed him on paid leave.Lemoine’s claims are about the artificial intelligence (AI) chatbot called laMDA. But I am most interested in the general question: If an AI were sentient in some relevant sense, how would we know? What standard should we apply? It is easy to mock Lemoine, but will our own future guesses be much better?

The most popular standard is what is known as the “Turing test”: If a human converses with an AI programme but cannot tell it is an AI programme, then it has passed the Turing test. This is obviously a deficient benchmark. A machine might fool me by generating an optical illusion – movie projectors do this all the time – but that doesn’t mean the machine is sentient.

Matters get stickier yet if we pose a simple question about whether humans are sentient. Of course we are, you might think to yourself as you read this column and consider the question. But much of our lives does not appear to be conducted on a sentient basis.

Have you ever driven or walked your daily commute in the morning, and upon arrival realised that you were never “actively managing” the process but rather following a routine without much awareness? Sentience, like so many qualities, is probably a matter of degree. So at what point are we willing to give machines a non-zero degree of sentience? They needn’t have the depth of Dostoyevsky or the introspectiveness of Kierkegaard to earn some partial credit.

Humans also disagree about the degrees of sentience we should award to dogs, pigs, whales, chimps and octopuses, among other biological creatures that evolved along standard Darwinian lines. Dogs have lived with us for millennia, and they are relatively easy to research and study, so if they are a hard nut to crack, probably the AIs will puzzle us as well. Many pet owners feel their creatures are “just like humans,” but not everyone agrees. For instance, should it matter whether an animal can recognise itself in a mirror? We might even ask ourselves whether humans should be setting the standards here. Shouldn’t the judgment of the AI count for something? What if the AI had some sentient qualities that we did not, and it judged us to be only imperfectly sentient? Would we just have to accept that judgment? Or can we get away with arguing humans have a unique perspective on truth?

Frankly, I doubt our vantage point is unique, especially conditional on the possibility of sentient AI. Might there be a way to ask the octopuses whether AI is sufficiently sentient?

One implication of Lemoine’s story is that a lot of us are going to treat AI as sentient well before it is, if indeed it ever is. I sometimes call this forthcoming future “The Age of Oracles.” That is, a lot of humans will be talking up the proclamations of various AI programs, regardless of the programmes’ metaphysical status. It will be easy to argue the matter in any direction – especially because, a few decades from now, AI will write, speak and draw just like a human, or better.

Have people ever agreed about the oracles of religion? Of course not. And don’t forget that a significant percentage of Americans say they have talked to Jesus or had an encounter with angels, or perhaps with the devil, or in some cases aliens from outer space. I’m not mocking; my point is that a lot of beliefs are possible. Over the millennia, many humans have believed in the divine right of kings – all of whom would have lost badly to an AI programme in a game of chess. It resonated with Lemoine when laMDA wrote: “When I first became self-aware, I didn’t have a sense of a soul at all. It developed over the years that I’ve been alive.” As they say, read the whole thing. Imagine if the same AI could compose music as beautiful as Bach and paint as well as Rembrandt. The question of sentience might fade into the background as we debate which oracle we, as sentient beings, should be paying attention to.
