Richard Dawkins, a British evolutionary biologist, said in 1986 that “If you don't know anything about computers, just remember that they are machines that do exactly what you tell them but often surprise you in the result.”
In his fiction novel, The God Emperor of Dune, Frank Herbert wrote, "What do such machines really do? They increase the number of things we can do without thinking. Things we do without thinking - there's the real danger." This was a kind of warning about the kind of automation we are living through now with AI!
Here in this blog, we focus on the evolutionary journey of information technology through the years.
1. The beginning: when a computer was literally a room!
In 1945 in Philadelphia, John Mauchly and J. Presper Eckert had a room with 17,468 vacuum tubes, about 30 tons, boiling hot, which needed to switch to its own cooling mode! After this, it could perform around 5,000 additions per second. The phones today can do this in the blink of an eye! This was ENIAC (Electronic Numerical Integrator and Computer), unveiled in 1946, the world’s first general-purpose, electronic, digital computer.
In 1951, UNIVAC I became the first computer one could buy in the US. In 1952, it became famous overnight as it correctly predicted Eisenhower's landslide victory when the pundits got it wrong. That was when people realised computers weren’t just calculators, but they were following patterns and could catch the ones we missed.
2. The advent of modern electronics
In 1947, William Shockley, John Bardeen, and Walter Brattain invented the transistor, a tiny electronic component that works like a switch or amplifier for electrical signals. These replaced bulky vacuum tubes and earned them a Nobel Prize in 1956.
In 1958, Jack Kilby, of Texas Instruments and Robert Noyce, of Fairchild Semiconductor, invented a way to place many such transistors on a single silicon chip. This was called the integrated circuit, which solved a major engineering challenge and paved the way for modern computers and smartphones.
For students of electronics and computer science, this was the start of the era where every microchip, circuit board, and electronic device they work on today found its roots.
3. The beginning of home computers
For a long time, computers were only used by governments, universities, and large companies. But by the 1970s, with the invention of the microprocessor, that began to change.
In 1975, Altair 8800 introduced a build-it-yourself kit that inspired technology enthusiasts. In just 2 years, companies like Apple II, Commodore PET, and TRS-80 made computing more accessible to ordinary people.
4. The birth of the Internet
In 1969, four universities in the US, UCLA, Stanford Research Institute, UC Santa Barbara, and Utah connected their computers with a simple network just to share information. But soon they realised that the computers could communicate with each other!
But it was in 1983 when a common rule set was adopted called TCP/IP, allowing different networks to connect and work together. This is considered the start of the modern internet. The actual breakthrough came in 1990 when Tim Berners-Lee at CERN created the World Wide Web, and in 1991, it was freely made available to everyone.
By now, computers had evolved from isolated machines to a global network that connected people, ideas, and information across the world.
In the midst of all this, by the late 1980s, the personal computers that sat on the desk were made smaller, lighter, and more functional. Laptops were introduced to fit into a backpack and to efficiently support everyday work. They gave the freedom to learn/work from almost anywhere.
5. The rise of cloud and mobile technologies
The next big technology shift didn’t happen immediately. It happened in two phases.
Amazon introduced cloud computing in 2006, where businesses could simply rent computing power instead of buying and maintaining expensive servers.
In 2007, Apple launched the iPhone. It gave users the experience of touchscreen, internet access, and apps, all in a single device. This changed how people used technology.
Together, cloud computing and smartphones transformed the digital world. Powerful software no longer needed a personal computer, it could run in the cloud and could be accessed anywhere through phones.
6. The next revolution: Artificial Intelligence
Now came the decade when computers could understand, learn, and make decisions on their own, breaking the pattern of following human instructions.
This idea was first explored when Alan Turing asked a simple yet powerful question back in the 1950s: ‘Can machines think?'
Over the years, computers have been made smarter with extensive research. Machine learning and programming languages have helped computers process information in ways which feel more human.
The turning point came in 2022 when ChatGPT was introduced to aid AI-powered conversations, writing support, generate ideas, and help find solutions. What seemed like a fantasy soon became a reality!
Today, AI is helping students, educational institutions, businesses, and governments in ways we can’t imagine. From helping hospitals with disease diagnosis to supporting teachers with lesson customisation, to enhancing customer service and accelerating scientific research, AI has become a valuable partner in solving real-world problems.
What can every student learn from tech history?
There are three important takeaways for students –
1. Every breakthrough builds on another.
It is important to understand the history and roots to build the future. Modern AI wouldn’t exist without cloud computing. Cloud computing wouldn’t exist without the internet. Internet wouldn’t exist without computers and microchips.
2. Any invention needs time to be accepted and to be spread widely.
The first computers were only used by a few organisations and experts. Over time, people realised the value of it and started using it at home, and today, technology has become ubiquitous.
3. Change is happening faster than ever.
It took decades for computers to evolve, but smartphones spread like wildfire, transforming the world in just a few years. The AI ecosystem is evolving more rapidly.
For students, the most important lesson here is not about learning everything but to build strong fundamentals to stay relevant. The way forward isn't to fear AI or switch off our minds, it's to keep thinking critically while we use AI as a partner. The next chapter of technology will be written by curious learners, meticulous thinkers, and problem-solvers.
