Technology has advanced significantly since the development of computers, and while machines undoubtedly played a critical role in its history, it is ultimately the people who helped shape it.
The history of technology was rooted in humans’ characteristics as restless problem-solvers, to provide effective solutions to woes that have long plagued global industries and to stretch the limits of what one can do.
From shaping the earliest tools from stone to coding algorithms that generate ideas, humans have continually sought methods to minimise effort and reduce errors. And although each technology is built differently, their origins have a common denominator – they all begin with a simple question: How can this be done better?
The Dawn of the Digital Age (1940s-1950s)
The birth of computers was not a sudden event but rather the culmination of centuries of addressing challenges.
Eight decades ago, computers were nothing like the sleek devices we know today. The world’s first all-electronic computer, Electronic Numerical Integrator And Computer (ENIAC), filled a room with wires, switches, and over 17,000 humming vacuum tubes in the 1940s.
This 30-tonne machinery is the brainchild of physicist John Mauchly and was fully developed post-World War II at the University of Pennsylvania. It was designed to quickly solve complex calculations that humans struggled to complete, but its invention was largely because of the need to support the United States Army on the battlefield.
Besides its enormous size, operating ENIAC was costly and came with hurdles, including having to manually rewire the machine. Despite its disadvantages, ENIAC was a step in the right direction.
While it may have marked the beginning of the digital age, the real breakthrough happened in the early 1950s with the development of the Universal Automatic Computer (UNIVAC).
Mauchly and engineer J. Presper Eckert used their expertise in building ENIAC to deliver UNIVAC, whose debut signals a shift from experimental machines to practical tools that could be applied to businesses, governments and everyday problem-solving, a great showcase of how technology changed work and life.
This eight-foot-tall machinery was an astounding feat of innovation during its time, capable of classifying an individual’s marital status, education, residence, age group, and birthplace, among others, in one-sixth of a second. But this advancement was miniscule compared to what made it popular – when it correctly predicted Dwight D. Eisenhower’s electoral victory in 1952.
ENIAC and UNIVAC laid the groundwork for everything that followed, demonstrating the raw potential of electronic computing and proving its value beyond the mathematical and science space.
Breaking Limits of Digital Transformation (1960s-1970s)
But as groundbreaking as ENIAC and UNIVAC were, their size and complexity revealed the need for something smaller, faster and more reliable, which was attained in the late 1950s through the invention of a microchip.
Although tiny – just the size of a fingernail – microchips are packed with thousands of electrical circuits, which Nobel Prize awardees and engineers Jack Kilby and Robert Noyce utilised to address the limited power of earlier machines.
Their invention not only resulted in reduced costs of operating computers but also paved the way for the development of personal computers (PCs), smartphones and other small electrical devices people use nowadays.
While microchips may have shrunk computers, it was the PC that brought them into society.
Before nations witnessed the rise of Apple Inc.’s MacBook line, there was Apple II, a PC developed in 1977 by Steve Jobs and Steve Wozniak. This custom-moulded plastic piece of hardware signals an invitation for people to explore, create and organise in ways once limited to big corporations and institutions.
Not long after, the IBM PC was invented, allowing users to plug it into the television and play games, redefining how people engaged and fast-tracking the development of the software industry.
The rise of these machines saw families balance budgets on a screen, students typing without a typewriter and small businesses managing data without needing to hire a specialist. The world saw that computers were no longer distant; they were personal.
When the World Went Online (1980s-1990s)
As PCs found their way into homes and offices, a new challenge emerged – how to connect them.
The Advanced Research Projects Agency Network (ARPANET) laid the groundwork for this in 1969. However, its usage was limited to government operations, which allowed authorities to share ideas and data instantly.
Despite its limited scope, ARPANET sparked a revolution, as its protocols and connections it inspired eventually grow into the Internet, a web that links billions of people today.
The birth of the Internet occurred when ARPANET adopted the TCP/IP protocol in 1983, enabling the connection of various networks into one unified system. This advancement made information accessible to anyone and is no longer confined to libraries or office cubicles.
With the Internet at our fingertips, experts wasted no time and developed tools that ultimately reshaped how we access information, communicate and collaborate online. The World Wide Web made knowledge clickable and navigable, email turned messages into instant conversations and search engines helped anyone find answers in split seconds.
Eventually, the entire world is in Web2. Social media platforms rose to popularity, emerging as hubs for conversation, self-expression and community-building, and suddenly, the Internet is no longer just a space for information-sharing but gradually became a participatory experience for all.
Blockchain Takes Back Digital Control (2010s-2020s)
While the advent of Web2 brought people together, it also posed an important question: who’s controlling our data?
This was because centralised platforms dominated communication, commerce and social interaction, leaving users with little ownership of their digital lives, sparking the development of blockchain technology in 1991 by research scientists Stuart Haber and W. Scott Stornetta.
Blockchain champions decentralisation, offering a new way to store and verify digital information. In the digital era, this decentralised ledger heralds a new form of trust online. But it is not just a mere record-keeping platform as blockchain also opened users to Web3, a digital world where users have ownership of their data, assets and online identities.
Web3 expands the concepts of blockchain – transparency, security and user control – to create a more extensive ecosystem, where the Internet itself becomes more democratic and user-driven.
While blockchain takes credit for creating a whole new vision of the Internet, its first breakthrough came with Bitcoin, a digital currency conceptualised by a certain Satoshi Nakamoto in 2008 that allowed people to send and receive payments without relying on banks or middlemen.
This simple yet revolutionary use case demonstrated the power of decentralised networks and trustless systems, but it did not stop there. Today, blockchain has grown into a tool for broader social and economic inclusion.
The Age of Smart Machines (2020s-Present)
Just as blockchain and Web3 are giving us more control over our digital lives, artificial intelligence (AI) is reshaping how we live and work.
While AI explosion only happened recently with the rise of chatbots like OpenAI’s ChatGPT and Google’s Gemini, this technology is nothing new, dating back in the 1950s and even gave rise to machine learning in the 1990s and 2000s.
Today, AI is capable of rapidly analysing mountains of data at lightning speed and even making decisions, which creates a mix of both fear and excitement among the public. While blockchain hands us ownership and trust, AI helps humans plan, create and solve problems faster and smarter.
The journey from early computers to today’s AI demonstrates how technology grows in tandem with human ambition. What started as massive machines designed to process calculations evolved into personal computers that empowered individuals, networks that connected the world and systems that give people ownership and a voice online.
Humans have come a long way in terms of advancing technology, and with our current capacity, it’s not impossible that innovation would stop at AI.
