背景知識
今日は月曜日。週の始まりは Writing Task 2（Opinion Essay） です。IELTS Academic の最重要セクションで、配点は Writing 全体の 67% を占めます。
今日のテーマ: AI と雇用
AI（人工知能）と自動化が急速に進む中、「AI が人間の仕事を奪う」という議論は世界規模で続いています。IELTS では Technology / Society / Economy カテゴリで頻出のトピックです。Opinion Essay では、一方の立場を明確に支持し、反論にも触れる構造が求められます。

Opinion Essay（"To what extent do you agree or disagree?" 型）では、立場を最初から明示することが最も重要です。「どちらとも言える」という曖昧な立場はスコアを下げます。

ヒント（段階的）
「完全に同意」「完全に反対」どちらでもよいですが、一方の立場を明確に取ることが TR（Task Response）のスコアに直結します。「一部同意」は中立すぎてスコアが下がる場合があります。
推奨立場：「AI は確かに雇用を奪う。特に低スキル労働者に深刻な影響がある」という立場で書くと論点が明確になります。
推奨立場：「AI は確かに雇用を奪う。特に低スキル労働者に深刻な影響がある」という立場で書くと論点が明確になります。
Body 1（AI が仕事を奪う）の論点:
- AI が代替しやすい職種：製造業の組み立て・コールセンター・データ入力・配送
- 低スキル労働者が最も打撃を受けることを説明
- 具体例：自動車工場でのロボット導入 → 人員削減の実例
- Concession：「新しい仕事が生まれる」という反論を認める（産業革命の歴史的前例）
- Rebuttal：しかしそれは AI エンジニア・データサイエンティストなど高度スキルを持つ人だけが恩恵を受ける
- 結論：平等の分配ではなく不平等の拡大につながる

Introduction
The rapid advancement of artificial intelligence and automation is fundamentally reshaping the global workforce. While some argue that these technologies will generate new employment opportunities, I firmly believe that their overall effect will be the widespread displacement of workers, particularly those in low-skilled occupations.
Body 1 — AI は雇用を奪う
There is compelling evidence that AI is already replacing humans in a wide range of routine roles. In manufacturing, robotic systems now perform assembly tasks with greater speed and precision than human workers, leading factories to drastically reduce their headcount. Similarly, in sectors such as retail and logistics, automated checkouts and delivery drones are eliminating thousands of entry-level positions. These displaced workers often lack the technical skills necessary to adapt, leaving them structurally unemployed and increasingly marginalised.
Body 2 — Concession + Rebuttal
Proponents of automation frequently argue that new industries will emerge to absorb the displaced workforce, much as the Industrial Revolution ultimately created more jobs than it destroyed. While this point has some historical merit, it overlooks a critical distinction: the jobs created by AI — such as machine learning engineers and data scientists — demand highly specialised qualifications that the majority of displaced low-skilled workers simply do not possess. Consequently, rather than redistributing prosperity, automation risks deepening existing socio-economic inequality.
Conclusion
In conclusion, I maintain that artificial intelligence poses a serious threat to employment, especially for vulnerable, low-skilled workers. To mitigate this harm, governments must invest heavily in retraining programmes and social safety nets that enable affected individuals to transition into emerging sectors.
