【解答例】

From healthcare to transportation, artificial intelligence (AI) is becoming deeply integrated into our society. Some fear AI’s potential downsides, but I strongly agree that AI will have a net positive impact on society overall.

First, AI has the capacity to greatly improve efficiency and productivity. Machines can process information and perform calculations far faster than humans, enabling breakthroughs in areas like medical diagnosis and climate modeling. This not only saves time but also helps solve complex problems that were previously intractable.

Second, AI can enhance our quality of life by taking over dangerous or tedious tasks. For instance, AI-powered robots can work in hazardous environments such as mines or nuclear reactors, reducing the risk to human workers. In daily life, automation of repetitive tasks frees people to engage in more creative and fulfilling activities, potentially leading to greater overall life satisfaction.

Third, AI-driven innovation can spur economic growth and create new industries. History shows that technological revolutions, despite initially disrupting some jobs, ultimately generate new kinds of employment. The AI sector itself is creating jobs in data science, programming, and ethics oversight. Moreover, AI is enabling personalized education and healthcare, which can lead to a more skilled workforce and healthier population in the long run.

Of course, we must address challenges such as ensuring ethical AI use and retraining workers affected by automation. However, with proper governance and adaptation, the benefits of AI—greater efficiency, safety, and innovation—far outweigh the drawbacks. Therefore, I am optimistic that artificial intelligence will on balance improve our society. (234words)
