Blaise Aguera y Arcas, polymath, novelist, and Google VP, has a way with words.
</p><p>
When he found himself impressed with Googles recent AI system LaMDA, he didnt just say, “Cool, it creates really neat sentences that in some ways seem contextually relevant”, he said, rather lyrically, in an interview with The Economist on Thursday,
</p><blockquote><p>
“I felt the ground shift under my feet … increasingly felt like I was talking to something intelligent.”
</p></blockquote><p>
Nonsense. Neither LaMDA nor any of its cousins (GPT-3) are remotely intelligent.<a href="#footnote-1" rel="">1</a> All they do is match patterns, draw from massive statistical databases of human language. The patterns might be cool, but language these systems utter doesnt actually mean anything at all. And it sure as hell doesnt mean that these systems are sentient.
</p><p>
Which doesnt mean that human beings cant be taken in. In our book Rebooting AI, Ernie Davis and I called this human tendency to be suckered by <em>The Gullibility Gap</em> — a pernicious, modern version of <a href="https://en.wikipedia.org/wiki/Pareidolia" rel="">pareidolia</a>, the anthromorphic bias that allows humans to see Mother Theresa in an image of a cinnamon bun.
</p><p>
Indeed, someone well-known at Google, Blake LeMoine, originally charged with studying how “safe” the system is, appears to have fallen in love with LaMDA, as if it were a family member or a colleague. (Newsflash: its not; its a spreadsheet for words.)
</p><p>
To be sentient is to be aware of yourself in the world; LaMDA simply isnt. Its just an illusion, in the grand history of ELIZA a 1965 piece of software that pretended to be a therapist (managing to fool some humans into thinking it was human), and Eugene Goostman, a wise-cracking 13-year-old-boy impersonating chatbot that won a scaled-down version of the Turing Test. None of the software in either of those systems has survived in modern efforts at “artificial general intelligence”, and I am not sure that LaMDA and its cousins will play any important role in the future of AI, either. What these systems do, no more and no less, is to put together sequences of words, but without any coherent understanding of the world behind them, like foreign language Scrabble players who use English words as point-scoring tools, without any clue about what that mean.
</p><p>
I am <em>not</em> saying that no software ever could connects its digital bits to the world, a la one reading of John Searles infamous Chinese Room thought experiment. Turn-by-turn navigations systems, for example, connect their bits to the world just fine.
</p><p>
Software like LaMDA simply doesnt; it doesnt even <em>try</em> to connect to the world at large, it just tries to be the best version of autocomplete it can be, by predicting what words best fit a given context. Roger Moore made this point beautifully a couple weeks ago, critique systems like LaMDA that are known as “language models”, and making the point that they dont understand language in the sense of relating sentences to the world, but just sequences of words to one another:

</p><p>
If the media is fretting over LaMDA being sentient (and leading the public to do the same), the AI community categorically isnt.
</p><p>
We in the AI community have our differences, but pretty much all of find the notion that LaMDA might be sentient completely ridiculous. Stanford economist Erik Brynjolfsson used this great analogy:
</p><img src="https://substackcdn.com/image/fetch/w_600,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fpbs.substack.com%2Fmedia%2FFVEHQukUsAAOe5i.jpg" alt="Image"/><p>
Paul Topping reminds us that all its doing is synthesizing human responses to similar questions:

Abeba Birhane, quoted at the top, pointed out the immense gap right now between media hype and public skepticism.

</p><p>
When some started wondering whether the world was going to end, LaMDA might beat an overrated 72 year old benchmark called The Turing Test I pointed to an <a href="https://www.newyorker.com/tech/annals-of-technology/what-comes-after-the-turing-test" rel="">old New Yorker article that I had written the last time gullibility exploded and Turing Test mania hit</a>, in 2014, when a program called Eugene Goostman was briefly famous, good enough to fool a few foolish judges for a few minutes. At the time, I pointed out that the test isnt particular meaningful, and that it had not stood the test of time. The public knows the test of course, but the AI community wishes it would go away; we all know that beating that test isnt meaningful.
</p><p>
Machine learning prof Tom Dietterich, never slow to needle me when he thinks I have gone too far, chimed in with full solidarity:
</p><p>
My old New Yorker article is still worth reading, for a bit of perspective, to see how things have and havent changed. Particularly amusing in hindsight is a quote from the Kevin Warwick, organizer of the 2014 Turing-ish competition, who predicted that, “[the program Eugene] Goostmans victory is a milestone [that] would go down in history as one of the most exciting” moments in the field of artificial intelligence.
</p><p>
I guess he felt the ground shift beneath his feet, too?
</p><p>
But 8 years later I doubt most people (even in AI) have ever even heard of his program, outside of my mentioning it here. It made <em>zero</em> lasting contribution to AI.
</p><p>
Fooling people into thinking a program is intelligent is just not the same as building programs that actually are intelligent.
</p><p>
§
</p><p>
Now heres the thing. In my view, we should be <em>happy</em> that LaMDA <em>isnt</em> sentient. Imagine how creepy would be if that a system that has no friends and family pretended to talk about them?
</p><p>
In truth, literally <em>everything</em> that the system says is bullshit. The sooner we all realize that Lamdas utterances are bullshit—just games with predictive word tools, and no real meaning (no friends, no family, no making people sad or happy or anything else) —the better off well be.
</p><p>
There are a lot of serious questions in AI, like how to make it safe, how to make it reliable, and how to make it trustworthy.
</p><p>
But there is no absolutely no reason whatever for us to waste time wondering whether anything anyone in 2022 knows how to build is sentient. It is not.
</p><p>
The sooner we can take the whole thing with a grain of salt, and realize that there is nothing to see here whatsoever, the better.
</p><p>
Enjoy the rest of your weekend, and dont fret about this for another minute :)
