シャドーイング練習: Three Specific Ways AI Could Kill Us All - 動画で英語スピーキングを学ぶ

By this point, you've probably heard that  AI could be really dangerous and possibly civilization-ending if it becomes  superintelligent and goes rogue.
2
But experts usually don’t speculate on  exactly what that means for us lowly humans.
3
So when the policy wonks over at Control AI  approached us about making a video about the dangers of unregulated AI, we  agreed, but on one condition: that we could get those experts to  describe a few specific scenarios in which superintelligent AI  really could wipe us off the map.
4
Hi, I’m David, and this is MinuteApocalypse.
5
One of the main goals of AI is to automate  tasks –often things that humans can't or don't want to do themselves– so the AI models  are built to be capable and independent.
6
But they’re getting so powerful and  so autonomous that many experts are convinced that soon AI will become  far more capable than any person, corporation or even nation –they'll attain  what scientists call "superintelligence".
7
They’ll be able to accomplish their goals in  ways we humans can’t anticipate – and even come up with their own goals. And since so much in our  lives is connected and controlled by computers, a superintelligent AI could conceivably hijack those  computers, thereby controlling almost everything.
8
But what kinds of real-life, civilization-ending  scenarios are experts actually worried about?
9
One example you might have heard about is  the so-called Paperclip Maximizer problem.
10
The gist is that an AI that's given computer  control over a smart factory and directed to make as many paperclips as possible  might decide that we humans are a good source of carbon for making the steel in those  paperclips – and use us all up in the process.
11
Of course, this maximization problem could  just as easily apply to an AI that – in trying to muster the computational power to,  say, solve the incredibly complicated Riemann hypothesis – takes over all the world’s data  centers to work on the problem, and then takes over all of the world's electrical grids and  directs them to send power to the data centers, which uses up all the energy in the world,  plunging humanity into chaos and darkness.
12
Or there’s the scenario in which a  super-intelligent AI – on a mission to create better conditions for the massive data centers that power it – starts  messing with Earth’s atmosphere.
13
Because while oxygen is a necessity for humans, it is not for AI; in fact,  the element causes corrosion.
14
So the AI might take control over computers in chemical plants in order to suck  all the oxygen out of the air, creating a perfect environment for machines  that just so happens to be deadly for us humans.
15
And then there’s the scenario where  AI actively tries to wipe out humans.
16
Like, let’s say an AI biological design  tool that has been programmed to develop new drugs decides that it doesn’t want  pesky humans interfering with its work.
17
It could use its skill set to create  a hyper-engineered pathogen designed to be resistant to all current medicines.
18
After all, doing so would kill off anyone  who could potentially shut it down.
19
Experts are all over the map when it  comes to how likely they think one of these situations – or some terrifying  variant of them – are to happen.
20
Ten percent seems to be an average – although some  experts think the likelihood is a lot higher. But most of them are pretty convinced that the dawn  of AI superintelligence – and the dangers that come with it – will be here very soon. And  we will definitely need some help with that.
21
Some of these scenarios are pretty scary,  but there’s still time to make a difference.
22
Right now, lawmakers are deciding what the  future of AI regulation will look like, and if you want to learn more or have your voice  heard, check out campaign.controlai.com. There, the experts at ControlAI – which sponsored  this video – have put together really helpful educational resources about the risk  of extinction from superintelligence, as well as simple and powerful  ways to get more involved.
23
ControlAI has already mobilized tens of  thousands of people to take action on this issue; in just the last few months, they’ve  sent over 50,000 messages to lawmakers.
24
They’re building the movement to  keep humanity in control. Go to campaign.controlai.com to help secure our future.

覚えておきたい単語・イディオム

  • superintelligent:超知能の。AIが人間を超える知能を持つことを表します。
  • rogue:暴走する。AIが制御不能になる様子を形容します。
  • maximizer:最大化するもの。「Paperclip Maximizer」は紙クリップを最大化するAIの例です。
  • hijack:乗っ取る。コンピューターシステムを不正に制御することです。

アクセントを正しくするコツ

この動画のスピーカーは速めの口調ですが、重要な単語にはアクセントが置かれています。例えば「superintelligent」や「civilization-ending」のような長い単語は、途中でアクセントを上げることで意味を明確にします。shadow speechをする際は、スピーカーのポーズや抑揚を真似ることで、自然な発音が身につきます。特に「scenario」や「pathogen」などの難しい単語は、繰り返し練習して正しい発音を覚えましょう。

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。
