- See you there! Hello. This is 6 Minute English from BBC Learning English.
- I'm Neil. And I'm Sam.
- Are you feeling well, Sam?
- No headache or sore throat?
- No, I feel fine. Thanks, Neil.
- Why do you ask? Well, I've been reading some inspirational stories about the doctors and nurses fighting Covid.
- When I was a boy, I always dreamed of becoming a doctor.
- Ah, I see. Have you ever been in hospital?
- Yes, I have. And I remember the nurse's bedside manner – you know, the kind and caring way that doctors and nurses treat people who are ill.
- Nowadays, more and more of the jobs that humans do are being carried out by machines.
- But I doubt that a doctor's bedside manner could easily be replaced by a robot.
- In this programme, we'll be discussing whether the revolution in artificial intelligence – often shortened to AI – could replace human doctors and nurses.
- We'll be asking, can you imagine a future without doctors?
- In fact, machines are already doing some of the jobs traditionally done by doctors – scanning people's bodies to detect skin cancer, for example.
- Yes, that's true, Sam, and it links to my quiz question, which is about human skin.
- It's a well-known fact that skin is the human body's largest organ.
- But how much skin does the average adult have?
- Is it a Of course, our skin gets loose as we age, but I can't believe there's three square metres of it.
- I'll say the answer is A – two square metres.
- OK, we'll find out if that's correct later.
- Every year in the UK, over five million people are treated for skin cancer.
- Catch it early and your chances of survival are increased.
- Usually a skin specialist or dermatologist will examine your skin using a hand-held microscope.
- But in 2017, a team of researchers at Stanford Medical School made an exciting announcement.
- Here's Oxford University researcher Daniel Suskind telling BBC World Service programme The Big Idea what the medics at Stanford had invented.
- The team of researchers at Stanford last year announced the development of a system that if you give it a photo of a freckle, it can tell you as accurately as 21 leading dermatologists whether or not that freckle is cancerous.
- The Stanford medical team had invented an AI system to analyse freckles, small brown spots found on people's skin, especially on pale skin.
- As it turned out, the AI programme was better than doctors, telling whether a freckle was harmless or cancerous, connected to some type of cancer.
- So it seems that artificial intelligence is already replacing humans when it comes to detecting cancer and doing a better job of it.
- But Daniel Susskind isn't convinced.
- One reason is that AI systems still need humans to programme them.
- And as it turns out, knowing exactly how doctors detect illness remains something of a mystery.
- Here's Daniel Susskind again in conversation with BBC World Service programme The Big Idea.
- If you ask a doctor how it is they make a diagnosis, they might be able to point you to particularly revealing parts of a reference book or give you a few rules of thumb, but ultimately they'd struggle.
- They'd say, again, it requires things like creativity and judgment, and these things are very difficult to articulate.
- And so traditionally it's been thought very hard to automate.
- If a human being can't explain how they do these special things, where on earth do we begin in writing instructions for a machine to follow?
- Most doctors find it difficult to explain how they make a diagnosis.
- Their judgment about what someone's particular sickness is made by examining them.
- Diagnosing someone's illness is complicated, but there are some rules of thumb.
- A rule of thumb is a practical but approximate way of doing something.
- For example, when cooking, a good rule of thumb is two portions of water to one portion of rice.
- Exactly. And because identifying sickness is so difficult, Daniel says, where on earth do we begin writing instructions for a machine?
- We use phrases like where, how or what on earth to show feelings like anger, surprise or disbelief.
- I might show surprise by asking Sam, how on earth did you know the answer to that?
- Aha! I guess you're talking about your quiz question, Neil.
- And you didn't be so surprised.
- I'm naturally brainy. Of course you are.
- In my quiz question, I asked Sam how much skin there is on an adult human body.
- And I said it was A, two square metres.
- Which was the correct answer.
- With your brains, I think you'd make a good doctor, Sam.
- and I'm sure you'd have a good bedside manner too.
- Ah, you mean the kind and caring way that doctors and nurses treat their patients.
- OK, let's recap the rest of the vocabulary, starting with freckle – a small brown spot on someone's skin.
- Freckles are usually harmless, but some skin spots can be cancerous – connected to cancer.
- A doctor's diagnosis is their judgement about what someone's particular sickness or disease is.
- A rule of thumb is a useful but approximate way of doing or measuring something.
- And finally, we use phrases like where on earth as a way to show emotions like anger, surprise or disbelief.
- That's all for this programme, but join us for the next edition of 6 Minute English when we'll discuss another trending topic and the related vocabulary.
- Why on earth would you miss it?
- Goodbye for now. Goodbye. 6 Minute English from the BBC.
