Artificial Intelligence (AI) sometimes asks us to conjure visions of a futuristic world – like a sci-fi epic that’s described in terms of robots, self-driving cars, and complex algorithms that imitate human behaviour. However, AI has been quietly weaving its way into our daily lives since 1950, long before it became a buzzword. From simple tasks like routing your morning commute to transforming entire industries, AI’s journey has been filled with groundbreaking milestones that have only truly been recognised for their impact in hindsight. Today, we’ll explore some of these pivotal moments in AI’s evolution.
The history of AI traces back to the mid-20th century, when visionary thinkers like Alan Turing laid the groundwork for what would become machine learning and artificial intelligence. Turing’s seminal 1950 paper, Computing Machinery and Intelligence, introduced the famous “Turing Test,” which questioned whether machines could think. This theoretical foundation set the stage for the development of AI as we know it.
However, it wasn’t until the 1960s when the first AI programs were created, including ELIZA – an early natural language processing computer program. While basic, these programs showcased AI’s potential to simulate human-like interactions. At this stage, AI was seen more as an academic curiosity, with limited practical application.
Dr. Fei-Fei Li, Co-Director of Stanford’s Human-Centered AI Institute, has noted, “AI’s early development was fuelled by theoretical exploration, but even then, the vision for its real-world impact was clear.”
While today we often think of AI in terms of complex systems, its first major impact on our daily lives came through more subtle applications. A classic example is traffic lights. Though not necessarily “intelligent” in the sense we imagine today, many early traffic light systems began to incorporate rudimentary AI algorithms to control traffic flow based on time of day, congestion, and other variables.
This technology, known as adaptive traffic control systems, used data inputs (such as traffic density and timing) to optimise signal changes without direct human intervention. While these systems were basic, they marked an early integration of AI in public infrastructure. Over time, this led to smarter traffic management systems, which now incorporate more advanced AI techniques, like real-time analytics and machine learning, to predict and adapt to traffic patterns.
According to AI researcher Dr. Kate Crawford, “The real power of AI has always been its ability to work quietly in the background, optimising systems we rely on without us even noticing.”
The early 2000s marked a significant shift, as AI moved from being a theoretical concept to a tool used in everyday services, particularly in internet-based applications. Search engines, most notably Google, began integrating AI algorithms that allowed them to provide more accurate search results based on users’ queries. AI-driven ranking systems, powered by complex algorithms, helped Google understand the context of each search, vastly improving the accuracy and relevance of results.
Additionally, the rise of email filters, powered by AI, introduced a new layer of automation to personal communication. These filters used machine learning to sort spam from legitimate emails, making communication more efficient and reducing the need for manual sorting.
In the legal world, this period also saw the emergence of AI-powered legal research tools. These systems began using AI to quickly sift through vast amounts of legal documents, significantly reducing the time lawyers spent conducting research.
Richard Susskind, a leading voice on AI in the legal industry, has stated, “AI is not replacing lawyers, but it is certainly changing the way they work, particularly when it comes to research and data analysis.”
The 2010s marked a turning point for AI, as it began to appear in personal devices we use every day. The introduction of smart assistants like Apple’s Siri, Amazon’s Alexa, and Google Assistant brought AI into the mainstream. These systems use voice recognition and machine learning to process and respond to commands, making it easier for users to interact with their devices without needing to type or touch screens.
From checking the weather to controlling home appliances, these assistants use AI to learn from user preferences and predict actions. In the legal sector, this shift is mirrored by the development of AI-driven legal tools that assist with contract analysis, case management, and even predicting the outcomes of legal proceedings.
Today, AI is revolutionising the legal industry, offering capabilities that were once thought impossible. Machine learning algorithms can now predict the outcomes of cases with remarkable accuracy, assisting lawyers in making more informed decisions. AI-driven document review and contract analysis tools save time and reduce human error, making routine legal tasks faster and more efficient.
Moreover, AI’s role in legal research has gone beyond simply searching databases. Modern AI tools can sift through millions of legal documents, summarise key points, and identify patterns, providing lawyers with insights that were previously buried in large volumes of text.
As legal AI expert Noah Waisberg puts it “AI is the biggest shift in legal work since the advent of the word processor. It’s not replacing lawyers—it’s enabling them to focus on higher-value work.”
