What invention in the last 30 years has made the most difference in the lives of people? Explain why it has had such a noteworthy effect. Use specific reasons and examples to support your choice.

毫無疑問，技術變化如此之快，以至於我們無法忽視它的存在。雖然它為人們做任何事情帶來了便利，但它對人類產生了不利的影響。以智能手機為例。在過去的三十年裡，它間接地改變了我們的生活方式，並產生了深遠的影響。隨著智能手機的發明，發送消息和進行交流變得更加靈活和方便，這表明我們不受限於我們是否在同一個地方。根據美國全國廣告公司的數據，超過 50% 的人經常使用手機發短信或聊天。此外，搜索信息是智能手機的另一個優勢。我們不僅可以獲得知識來豐富自己，還可以通過關注時事來開闊視野。如今，執法部門通過智能手機對違反（違反）防疫規定的人員進行合法監控。因此，智能手機在我們的生活中發揮著重要作用。正如諺語所說，“每個角落都有兩個側面。”換句話說，智能手機逐漸成為人們日常聊天和處理任務的不可或缺的媒介，但它們很可能為犯罪分子提供了網絡犯罪的機會欺詐和性行為不端。此外，我們在智能手機上的個人信息和照片可能會被黑客入侵，從而可能引發國家安全危機。鑑於智能手機的多功能和時尚外觀，人們會一個接一個地購買它們，而不考慮他們是否買得起。最終，我們陷入了一個惡性循環。智能手機有利有弊。一方面，疫情期間可以管理我們的任務，互相交流，執行法規；另一方面，它有侵犯人權，擾亂社會秩序和國家安全的風險。綜上所述，我們作為智能手機的發明者，應該物盡其用，而不是被它們控制。擾亂社會秩序和危害國家安全。綜上所述，我們作為智能手機的發明者，應該物盡其用，而不是被它們控制。擾亂社會秩序和危害國家安全。綜上所述，我們作為智能手機的發明者，應該物盡其用，而不是被它們控制。
