This blog post explores the changes the Fourth Industrial Revolution, centered on artificial intelligence, will bring to our daily lives and society.
“Jarvis!” In the movie Iron Man, protagonist Tony Stark calls his AI assistant Jarvis as if it were a person, issuing commands and entrusting it with complex tasks. Jarvis, a high-performance AI system that recognizes voice, converses, and performs various tasks, sparked anticipation for ‘future technology’ in many people. A few years later, in 2016, AI once again captured public attention when AlphaGo, an AI that defeated humans in a Go match against Lee Sedol, emerged. This rapid advancement in AI technology soon led to the massive wave known as the ‘Fourth Industrial Revolution,’ and we now stand at its center.
As of 2024, the entire world is embracing the ‘Fourth Industrial Revolution,’ centered on artificial intelligence and digital technology. The ‘Fourth Industrial Revolution’ signifies more than just technological progress. This wave of innovation is reshaping societal structures, redefining industrial paradigms, and profoundly impacting everyday human life. Particularly in recent years, with the emergence of generative AI (e.g., ChatGPT, Claude, Gemini), AI is evolving beyond mere tools into ‘intelligent companions’ capable of collaborating with humans and even enabling creative work.
The term ‘Fourth Industrial Revolution’ was first officially mentioned at the 2016 World Economic Forum (Davos Forum). Klaus Schwab, then Chairman of the Forum, defined it as “a technological revolution that merges the boundaries of digital, bio, and physics technologies, building upon the Third Industrial Revolution.” This signifies a societal transformation driven by the convergence and advancement of existing technologies, rather than solely the emergence of new ones. In other words, the Fourth Industrial Revolution is an era built upon the information and communication technologies (ICT) developed during the Third Industrial Revolution, but one where diverse technologies—such as artificial intelligence, the Internet of Things (IoT), big data, cloud computing, biotechnology, robotics, and quantum computing—interconnect to create new value.
The core keywords of the Fourth Industrial Revolution are ‘Hyperconnectivity’ and ‘Superintelligence’. Hyperconnectivity refers to the phenomenon where people, objects, services, and infrastructure are connected in real-time via the internet. Superintelligence signifies the ability of AI to analyze and process the vast data collected through these connections, enabling insights and decision-making that surpass human capabilities. For instance, AI-based personalized services are increasingly integrated into daily life. Smartphone AI assistants understand users’ schedules and habits to provide notifications, while streaming services analyze preferences to recommend content. Technologies like Korea’s ‘Kakao AI Speaker’ or ‘Naver Clova’ go beyond simple command execution, learning from user data to respond with increasing sophistication.
In this way, AI is naturally integrating into our lives and driving innovation across industries. In healthcare, AI is used for image interpretation and diagnostic assistance. In finance, it analyzes customer spending patterns to suggest tailored financial products or detect suspicious transactions in real time. In manufacturing, smart factories are being introduced, contributing to increased productivity and reduced defect rates. The presence of AI is growing increasingly prominent across diverse fields like autonomous vehicles, drones, and robots.
Particularly since 2023, the explosive rise of generative AI has sparked a surge in social interest. As AI gains the ability to generate diverse content like text, images, voice, and video, it is performing practical tasks across multiple domains, including content creation, customer service, programming, and translation. For instance, one small business implemented GPT-based AI in its customer service chatbot, achieving a reduction of over half its operational time. Teachers are also leveraging generative AI to prepare lesson materials, enhancing the quality of education.
However, concerns also exist. According to a late 2023 survey by the U.S. Pew Research Center, 55% of respondents expressed “concern” about AI replacing jobs, while also voicing unease about AI potentially spreading misinformation or making biased decisions. Indeed, issues of AI ethics, transparency, and accountability are among the hottest topics of discussion today. The European Union (EU) passed the ‘AI Act’ in 2024, establishing regulatory standards for high-risk AI systems. South Korea is also discussing the enactment of ‘AI Ethical Standards’ and a ‘Basic AI Act’.
So, what exactly is artificial intelligence (AI)? Many people perceive AI solely as robots that think and speak like humans, but in reality, AI is a technical concept encompassing all ‘intelligent computer systems’. The term AI was first proposed by American computer scientist John McCarthy at the 1956 Dartmouth Conference, where he defined it as “the science and engineering of making intelligent machines, especially intelligent computer programs.” At the time, AI research received little attention due to limited computing power and data. Today, however, advancements in cloud computing, big data, and high-performance computing have ushered in an era where AI delivers tangible results.
Current artificial intelligence is developing primarily in two directions. One is ‘narrow AI,’ specialized for specific tasks, and the other is ‘general AI,’ capable of performing diverse tasks like humans. Most AI we currently use falls under Narrow AI, demonstrating accuracy and efficiency surpassing humans in specific tasks. However, recent generative AI is increasingly expanding towards the form of General AI, simultaneously carrying both its potential and risks.
Ultimately, the Fourth Industrial Revolution and artificial intelligence are like a two-headed chariot propelling each other forward. AI is the core engine and catalyst of the Fourth Industrial Revolution, while conversely, the momentum of the Fourth Industrial Revolution has enabled the rapid advancement of AI technology. We are living in a time of immense change, and this technological shift could be an opportunity to enhance quality of life or a source of anxiety threatening existing jobs.
What matters is how we embrace and respond to this change. Technology is neutral. Whether it proves beneficial or harmful depends on the choices of its users and society. Therefore, we must not blindly fear AI or view it as an object of unconditional hope; instead, we must continuously learn and deliberate to ensure its development and utilization proceed in the right direction.
Alvin Toffler stated, “The future cannot be predicted, but it can be invented.” In this Fourth Industrial Revolution era alongside artificial intelligence, we must become ‘active creators’ who design and lead the future, not merely beings swept along by change. Amidst this massive current, we must never forget that what truly matters is not the technology itself, but ultimately the ‘human beings’ who wield it.
