  • Hello. This is 6 Minute English from

  • BBC Learning English. I’m Sam.

  • And I’m Neil.

  • In the autumn of 2021, something

  • strange happened at the Google

  • headquarters in California’s Silicon

  • Valley. A software engineer called,

  • Blake Lemoine, was working on the

  • artificial intelligence project, ‘Language

  • Models for Dialogue Applications’, or

  • LaMDA for short. LaMDA is a

  • chatbot – a computer programme

  • designed to have conversations with

  • humans over the internet.

  • After months talking with LaMDA

  • on topics ranging from movies to

  • the meaning of life, Blake came to

  • a surprising conclusion: the chatbot

  • was an intelligent person with wishes

  • and rights that should be respected.

  • For Blake, LaMDA was a Google

  • employee, not a machine.

  • He also called it hisfriend’.

  • Google quickly reassigned Blake from

  • the project, announcing that his ideas

  • were not supported by the evidence.

  • But what exactly was going on?

  • In this programme, well be

  • discussing whether artificial intelligence

  • is capable of consciousness. Well hear

  • from one expert who thinks AI is not as

  • intelligent as we sometimes think,

  • and as usual, well be learning some

  • new vocabulary as well.

  • But before that, I have a question for

  • you, Neil. What happened to Blake Lemoine

  • is strangely similar to the 2013 Hollywood

  • movie, Her, starring Joaquin Phoenix as

  • a lonely writer who talks with his

  • computer, voiced by Scarlett Johansson.

  • But what happens at the end

  • of the movie? Is it:

  • a) the computer comes to life?

  • b) the computer dreams about the writer? or,

  • c) the writer falls in love with the computer?

  • ... c) the writer falls in love with the computer.

  • OK, Neil, I’ll reveal the answer at the end

  • of the programme. Although Hollywood is

  • full of movies about robots coming to life,

  • Emily Bender, a professor of linguistics and

  • computing at the University of Washington,

  • thinks AI isn’t that smart. She thinks the

  • words we use to talk about technology,

  • phrases likemachine learning’, give a

  • false impression about what

  • computers can and can’t do.

  • Here is Professor Bender discussing

  • another misleading phrase, ‘speech

  • recognition’, with BBC World Service

  • programme, The Inquiry:

  • If you talk aboutautomatic speech

  • recognition’, the termrecognition

  • suggests that there's something

  • cognitive going on, where I think a

  • better term would be automatic transcription.

  • That just describes the input-output

  • relation, and not any theory or wishful

  • thinking about what the computer is

  • doing to be able to achieve that.

  • Using words likerecognitionin relation

  • to computers gives the idea that

  • something cognitive is happeningsomething

  • related to the mental processes of

  • thinking, knowing, learning and understanding.

  • But thinking and knowing are human,

  • not machine, activities. Professor Benders

  • says that talking about them in connection

  • with computers is wishful thinking -

  • something which is unlikely to happen.

  • The problem with using words in this

  • way is that it reinforces what

  • Professor Bender calls, technical

  • biasthe assumption that the computer

  • is always right. When we encounter

  • language that sounds natural, but is

  • coming from a computer, humans

  • can’t help but imagine a mind behind

  • the language, even when there isn’t one.

  • In other words, we anthropomorphise

  • computerswe treat them as if they

  • were human. Here’s Professor Bender

  • again, discussing this idea with

  • Charmaine Cozier, presenter of BBC

  • World Service’s, the Inquiry.

  • Soismmeans system, ‘anthrooranthropo

  • means human, andmorphmeans shape...

  • And so this is a system that puts the

  • shape of a human on something, and

  • in this case the something is a computer.

  • We anthropomorphise animals all the time,

  • but we also anthropomorphise action figures,

  • or dolls, or companies when we talk about

  • companies having intentions and so on.

  • We very much are in the habit of seeing

  • ourselves in the world around us.

  • And while were busy seeing ourselves

  • by assigning human traits to things that

  • are not, we risk being blindsided.

  • The more fluent that text is, the more

  • different topics it can converse on, the

  • more chances there are to get taken in.

  • If we treat computers as if they could think,

  • we might get blindsided, or

  • unpleasantly surprised. Artificial intelligence

  • works by finding patterns in massive

  • amounts of data, so it can seem like

  • were talking with a human, instead

  • of a machine doing data analysis.

  • As a result, we get taken inwere tricked

  • or deceived into thinking were dealing

  • with a human, or with something intelligent.

  • Powerful AI can make machines appear conscious,

  • but even tech giants like Google are years

  • away from building computers that can

  • dream or fall in love. Speaking of which,

  • Sam, what was the answer to your question?

  • I asked what happened in the 2013 movie, Her.

  • Neil thought that the main character

  • falls in love with his computer, which

  • was the correct answer!

  • OK. Right, it’s time to recap the vocabulary

  • weve learned from this programme about AI,

  • including chatbots - computer programmes

  • designed to interact with

  • humans over the internet.

  • The adjective cognitive describes

  • anything connected with the mental

  • processes of knowing,

  • learning and understanding.

  • Wishful thinking means thinking that

  • something which is very unlikely to happen

  • might happen one day in the future.

  • To anthropomorphise an object means

  • to treat it as if it were human,

  • even though it’s not.

  • When youre blindsided, youre

  • surprised in a negative way.

  • And finally, to get taken in by someone means

  • to be deceived or tricked by them.

  • My computer tells me that our six minutes

  • are up! Join us again soon, for now

  • it’s goodbye from us.

  • Bye!
