Reading Passage: The Rise of Artificial Intelligence in Modern Society
Paragraph A
The history of artificial intelligence (AI) can be traced back to ancient myths of automatons, but it was only in the twentieth century that the concept began to materialise as a serious scientific discipline. Early pioneers like Alan Turing and John McCarthy speculated about the possibility of constructing machines capable of reasoning, learning, and problem-solving. Turing’s question—“Can machines think?”—set the tone for decades of research, debate, and technological breakthroughs.
Paragraph B
With the development of digital computers in the 1950s and 1960s, computer scientists created the first programs that could perform simple tasks such as playing chess or solving algebraic equations. While these accomplishments were impressive, they revealed the inherent difficulties in replicating human intelligence. Even the most powerful computers of the era struggled with tasks that seemed effortless to children, such as recognising objects or understanding spoken language.
Paragraph C
The progress of AI research has often been characterised by cycles of optimism and disappointment. Periods of rapid advancement—such as the introduction of “expert systems” in the 1980s—were frequently followed by what researchers termed “AI winters,” when funding and public interest waned due to unmet expectations. Nevertheless, foundational work in machine learning, neural networks, and natural language processing continued in academic circles, quietly laying the groundwork for future breakthroughs.
Paragraph D
A dramatic shift occurred in the early 2010s, when advances in computer hardware and the availability of vast data sets enabled deep learning algorithms to outperform humans at image and speech recognition tasks. High-profile victories, such as IBM’s Watson winning the quiz show Jeopardy! and Google DeepMind’s AlphaGo defeating a world champion at the game of Go, captured the world’s imagination. Companies began to deploy AI-driven technologies in fields as varied as healthcare, finance, logistics, and entertainment.
Paragraph E
Today, AI applications have permeated daily life in ways that were once the realm of science fiction. Voice assistants respond to natural language queries, recommendation systems personalise online experiences, and autonomous vehicles are being tested on public roads. The ability of algorithms to analyse immense amounts of data and identify subtle patterns has made them indispensable tools for scientific research and business optimisation.
Paragraph F
Yet the rapid integration of AI has raised profound ethical, economic, and social questions. There is widespread concern about the potential for job displacement as machines automate routine work, leading to debates about universal basic income and the future of employment. Additionally, AI systems have occasionally demonstrated bias or produced opaque decisions that are difficult to interpret or challenge, prompting calls for greater transparency and accountability in algorithmic design.
Paragraph G
Governments and international organisations have begun to propose regulations aimed at ensuring that AI is developed and used responsibly. Some suggest that ethical frameworks should be established to govern not only the safety and privacy of users but also the broader societal impacts of new technologies. At the same time, there is a global race to achieve leadership in AI, as countries recognise its strategic importance for national security and economic competitiveness.
Paragraph H
Looking ahead, most experts agree that collaboration across disciplines and borders will be vital for addressing the challenges and opportunities presented by AI. Ongoing research seeks to make artificial intelligence more transparent, robust, and aligned with human values. Whether the future of AI is one of empowerment or risk depends on decisions made today by scientists, policymakers, and society at large.
