Technologies that Changed the World 1

Getting Started

We're going to talk about 10 technologies that have revolutionized our lives. From the smartphones we use every day to the amazing space exploration technologies, there are so many technologies that have changed the world. We've selected some of the most impressive ones.

The Birth and Global Spread of the Internet

Developed by the US Department of Defense in 1969, the internet has rapidly spread across the globe, bringing about significant changes to human life.

The birth of the internet was aimed at facilitating communication between computers. Initially used for military purposes, it later began to be utilized in various fields such as academic research and business activities. With the advent of the World Wide Web (WWW) in the 1990s, the internet became mainstream, and currently, about half of the world's population uses the internet.

The internet has facilitated information gathering and sharing, expanding the scope of knowledge, and promoted communication and collaboration among people, strengthening social relationships. It has also fostered the development of the digital economy, including e-commerce and online banking, creating economic value and playing a major role in the advancement of future technologies such as artificial intelligence and big data.

However, the spread of the internet has also brought about side effects. Security issues such as personal information leaks and cybercrime have increased, and social problems such as internet addiction have also emerged.

Nevertheless, the internet remains one of the most important technologies in modern society, and its influence continues to expand.

The Smartphone Revolution and Changes in Communication

The smartphone revolution, which began with Apple's launch of the iPhone in 2007, has sent ripples across the globe.

Unlike conventional mobile phones, smartphones are equipped with operating systems and app stores, offering a wide range of functionalities. This has enabled people to access the internet, search for information, connect with friends through social media, play games, listen to music, and watch videos anytime, anywhere.

It has also brought about significant changes in communication methods. Instead of traditional text messages or phone calls, it has become commonplace to use social media platforms like KakaoTalk, Facebook Messenger, and Instagram for real-time conversations. Sharing and enjoying diverse content through video platforms like YouTube and Netflix has also become widespread.

Smartphones have also revolutionized the way we work. Using email, cloud services, and office apps, people can now handle tasks outside the office, leading to the rise of remote work and work-from-home arrangements.

These changes have provided many conveniences to human lives, but they have also revealed problems. Excessive smartphone use has led to an increase in health issues such as text neck syndrome, vision problems, and insomnia, and social problems such as social media addiction have also emerged.

The Advancement of Artificial Intelligence and Its Application in Daily Life

Artificial intelligence (AI) is a concept built upon computer science and cognitive science, representing a technology that enables machines to mimic and implement human intelligence and behavior. First introduced by Professor John McCarthy in 1956, it has rapidly evolved since then.

It is being applied in various aspects of our daily lives, changing the way we live. Prime examples include voice assistants such as Siri, Google Assistant, and Kakao. They recognize user voice commands and provide information on weather, schedules, news, play music, make calls, and perform other functions.

Furthermore, it uses image recognition technology to identify objects or individuals in photos, and facial recognition technology to establish security systems. AI technology is also being used in self-driving cars. By recognizing the surrounding environment and making independent judgments to control driving, it enables safe and convenient driving.

In the medical field, AI technology is being actively utilized to analyze medical images like CT and MRI scans to diagnose diseases such as cancer and dementia, and suggest treatment options. It is also being applied in drug development, helping to analyze experimental results and discover new drug candidates.

Thus, AI continues to advance, and its potential and possibilities are limitless. In the future, we anticipate that AI will develop further, making human lives even more prosperous and convenient.
