6 Minute English from bbclearningenglish.com Hello and welcome to 6 Minute English.
2
I'm Catherine.
3
And hello, I'm Rob.
4
Today we have another technology topic.
5
Oh good, I love technology.
6
It makes things easier, it's fast and means I can have gadgets.
7
Do you think that technology can actually do things better than humans?
8
For some things, yes.
9
I think cars that drive themselves will be safer than humans,
10
but that will take away some of the pleasure of driving.
11
So I guess it depends on what you mean by better.
12
Good point, Rob.
13
And that actually ties in very closely with today's topic, which is techno-chauvinism.
14
What's that?
15
We'll find out shortly, Rob,
16
but before we do, today's quiz question.
17
Artificial intelligence, or AI, is an area of computer science
18
that develops the ability of computers to learn to do things like solve problems or drive cars without crashing.
19
But in what decade was the term artificial intelligence coined?
20
Was it a the 1940s,
21
b the 1950s or c the 1960s?
22
I think it's quite a new expression,
23
so I'll go for c the 1960s.
24
Good luck with that, Rob,
25
and we'll give you the answer later in the programme.
26
Now, let's get back to our topic of techno-chauvinism.
27
I know what a chauvinist is – it's someone who thinks that their country or race or sex is better than others.
28
But how does this relate to technology?
29
We're about to find out.
30
Meredith Broussard is Professor of Journalism at New York University and she's written a book called Artificial Unintelligence.
31
She appeared on the BBC Radio 4 programme more or less to talk about it.
32
Listen carefully and find out her definition of techno-chauvinism.
33
Techno-chauvinism is the idea that technology is always the highest and best solution.
34
So somehow over the past couple of decades,
35
we got into the habit of thinking
36
that doing something with a computer is always the best and most objective way to do something.
37
And that's simply not true.
38
Computers are not objective, they are proxies for the people who make them.
39
What is Meredith Broussard's definition of techno-chauvinism?
40
It's this idea that using technology is better than not using technology.
41
She says that we have this idea that a computer is objective.
42
Something that's objective is neutral.
43
It doesn't have an opinion.
44
It's fair and it's unbiased.
45
So it's the opposite of being a chauvinist.
46
But Meredith Broussard says this is not true.
47
She argues that computers are not objective.
48
They are proxies for the people that make them.
49
You might know the word proxy when you're using your computer in one country
50
and want to look at something that is only available in a different country.
51
You can use a piece of software called a proxy to do that.
52
But a proxy is also a person or a thing that carries out your wishes and your instructions for you.
53
So computers are only as smart or as objective as the people that programme them.
54
Computers are proxies for their programmers.
55
Broussard says that believing too much in artificial intelligence can make the world worse.
56
Let's hear a bit more.
57
This time, find out what serious problems in society does she think may be reflected in AI?
58
It's a nuanced problem.
59
What we have is data on the world as it is,
60
and we have serious problems with racism,
61
sexism, classism, ageism in the world right now.
62
So there is no such thing as perfect data.
63
We also have a problem inside the tech world where the
64
creators of algorithms do not have sufficient awareness of social issues such
65
that they can make good technology that gets us closer to a world as it should be.
66
She said that society has problems with racism, sexism, classism and ageism.
67
And she says it's a nuanced problem.
68
A nuanced problem is not simple but it does have small
69
and important areas which may be hard to spot but they need to be considered.
70
And she also talked about algorithms used to programme these technological systems.
71
An algorithm is a set of instructions that computers use to perform their tasks.
72
Essentially, it's the rules that they use to come up with their answers
73
and Broussard believes that technology will reflect the views of those who create the algorithms.
74
Next time you're using a piece of software or your favourite app,
75
you might find yourself wondering if it's a useful tool
76
or does it contain these little nuances that reflect the views of the developer?
77
Right, Catherine, how about the answer to this week's question then?
78
I asked in which decade was the term artificial intelligence coined?
79
Was it the 40s, the 50s or the 60s?
80
And I said the 60s.
81
But it was actually the 1950s.
82
Never mind, Rob.
83
Let's review today's vocabulary.
84
Well, we had a chauvinist – that's someone who believes their country,
85
race or sex is better than any others.
86
And this gives us techno-chauvinism – the belief that a technological solution is always a better solution to a problem.
87
Next, someone or something that is objective is neutral, fair and balanced.
88
A proxy is a piece of software,
89
but also someone who does something for you on your behalf.
90
A nuanced problem is a subtle one.
91
It's not a simple case of right or wrong.
92
In a nuanced problem, there are small but important things that you need to consider.
93
And an algorithm is a set of software instructions for a computer system.
94
Well, that's all we have time for today.
95
Goodbye for now.
96
Bye bye.

このビデオで話す練習をする理由は？
テクノロジーについての話題は、私たちの日常生活における重要な側面です。この動画では、人工知能やコンピュータの客観性について議論されており、英語スピーキング練習を通じて、これらのコンセプトを深く理解することができます。話すことによって、相手とのコミュニケーション能力を向上させるだけでなく、自信を持って意見を表現する力を養うことができます。特に、このような専門的なテーマについて話すことは、あなたの語彙を豊かにし、英語での思考をスムーズにします。shadow speechを実践し、発音やリズムを改善することは、英語スピーキング練習において非常に効果的です。
文法と表現を文脈で学ぶ
この動画では、以下のような重要な文法構造と表現が使われています。
- 「think that～」：何かについて考える際によく使われる表現で、自分の意見を述べるのに役立ちます。
- 「is not true」：否定の表現で、新たな知識や反論をする際に有効です。
- 「are proxies for」：何かの代理であることを示す表現で、特にテクノロジーの文脈では重要です。
- 「we got into the habit of」：習慣について述べる際に使われるフレーズです。
これらの表現をshadow speakで練習することは、リアルな会話の中で非常に役立ちます。
一般的な発音の罠
動画中にはいくつかの発音が難しい言葉やアクセントがあります。特に注意すべきは、「technology」や「objectivity」です。これらの単語は早口で話す際に、発音ミスをしやすいので、何度も練習してください。また、「artificial intelligence」のような長いフレーズも、正しいリズムで発音することが重要です。英語の発音を良くするためには、shadowingを利用して、著名なスピーカーの発音を模倣してみてください。この練習により、正しい発音が身につき、流暢さが増します。
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
