I was hooked! It was my first exposure to a computer though I had read about these in the newspapers and seen them on television. I think it was a Spectrum personal computer popular in the 1980s. My friend, Sanjay and I did a few simple tasks and played a few games on the computer. The games of the 80’s were slow and clunky by today’s standards. In those days however they were interesting and enticing. BASIC was the most popular computer language then. We also had COBOL and a few others. My good friend, Sanjay Mhatre was a bibliophile and a free thinker, and I often used to visit his place and borrow from his vast book collection. However, even in the 1980s there was uneasiness and opposition to computers and the fear that it would replace people and lead to mass unemployment was often mentioned.
The rise of information technology (IT) and the important role to be played by Indian companies was still in the future. I expect artificial intelligence (AI) will also open new jobs in the future. At my medical college in Thrissur, Kerala, India computers were still rare. Communist Kerala had a love-hate relationship with computers and technology. Maharashtra (a western Indian state) was an early adopter of computers, and my tenth- and twelfth-mark sheets were computerised while my MBBS ones were handwritten. During my postgraduation at Chandigarh, computers gained prominence in our conversations. Our head of the department was gracious enough to offer the services of his secretary for typing our research manuscripts when she was free. The only other option was to pay for the service from outside providers. In those days WordStar and WordPerfect dominated word processing.
Creating slides for presentations was a challenge. LCD projectors were not available, and we had to create physical slides with cardboard mounting. The slides were created on early versions of PowerPoint and photographed using a camera to create the physical ones. My co-guide, Dr Anil Grover (then a cardiologist) at Postgraduate Institute (PGI), Chandigarh mentioned how computers will become increasingly common and encouraged me to learn the Microsoft package of Word, PowerPoint, and Excel. PGI also started offering email facility on a limited basis. You had to write down the details of your email and take it to the IT section who will send your message. We had modems then, which took a while to connect and made a series of sounds with flashing lights while connecting to the internet.
In Pokhara, Nepal at the beginning of the twenty-first century, internet was still a luxury. Manipal College of Medical Sciences used to charge 10 Nepalese rupees to send a message. Faculty could type their message in Outlook and twice a day, the IT person would send and receive messages. In those days, a floppy disk was the most common external storage device, and I soon had a large and colourful collection of floppies. Floppies were not always reliable and sometimes the data on them could not be read. CD-ROMs were another storage device, but CD writers never became commonplace. At Mahendra Pul in the heart of Pokhara, a new cybercafé came up in the early 2000s offering internet browsing at 150 Nepalese rupees per hour. Compared to what we were previously paying, this was a steal!
The college also had an LCD projector though it was not commonly used by faculty members for teaching-learning. This was a large and clunky device. Earlier versions often had compatibility issues. You create your slides and hope for the best. These may or may not open on the laptop and may or may not be projected. One had to have a backup of the lecture on overhead projector (OHP) transparencies, just in case. We did not yet have easy access to computers or laptops. This came only later when the United States Pharmacopeia (USP) set up a drug information and pharmacovigilance centre at the teaching hospital. We got two excellent Dell computers, and the hospital provided us with internet.
The early computers were slow with a big, bulky, and heavy cathode ray screen. They had a blinking cursor and words appeared slowly after typing. The Hollywood movie, You’ve Got Mail (1998), follows the romance between Meg Ryan and Tom Hanks developed through email. The movie is a good introduction to the early days of the internet.
We had purchased a home desktop computer in 2001 or 2002. This purchase was a financial disaster. The computer required frequent repairs and drained our finances. Google launched its beta version of email, Gmail in 2004, and I was one of the early adapters. I became a fan of Gmail right from the start. It offered significant advantages over the then dominant Hotmail, Yahoo mail and Rediff mail. The storage was larger and there was no need to delete your old emails. Kist Medical College in Lalitpur, Nepal had purchased Dell desktop computers, and these were among the best ones I had used. Fast and responsive with good memory and speed. These had LCD monitors and looked sleek and modern.
Computer technology has made significant advances. I read that if cars had made similar advances to computers we could drive to the moon and back on a litre of gasoline. Chips started getting smaller and more powerful and are today fought over by the global technology superpowers. A variety of online applications started making their appearance with the spread of the internet. Some of these eventually became the internet giants of today. In India, internet became widely available, and the costs dropped significantly. Mobile technology also made dramatic advances. In India most people access the internet and carry out online tasks using their mobile phones. For around 12000 Indian rupees today you can get a decent mid-range phone. Today mobiles in the palm of your hands have greater processing power than the giants of the 1950s and 1960s. I remember reading a comic strip where a visitor from the future time travels to the present. He laughs on seeing the supercomputer, the most powerful one on earth. When asked why he shows a small ball and introduces it as a computer from his time with much greater processing power than the humungous supercomputer.
One of the major advances has been cloud computing and cloud services. We have Chromebooks that work on web-based applications and needs the internet to do things. Both Google and Microsoft offer a range of services including storage, meetings, messaging, and applications for text, presentations, and calculations. AI is now an integral part of applications. PowerPoint offers the designer option for slides and creates stunning backgrounds. I recently attended a workshop on Copilot, the AI support software from Microsoft that is fully integrated into all their applications. I like the transcribing option for interviews and focus groups offered by Teams and later by Zoom and this makes my life as a researcher easier.
When I was growing up, I had no clue about what would soon become commonplace. The world wide web, the ability to browse libraries and art collections, video conferencing, online work processes, applying for government and other services online, online fund transfer and remittance are now at our fingertips. The COVID pandemic shifted a lot of learning and even assessment online. Presently we mainly interact with computers using a keyboard. I am a fan of the sci-fi series, Star Trek, where people interact with computers mainly using their voice. Voice commands are already available and steadily improving.
I was slow getting into social media. Their judicious use is to be recommended. Facebook keeps me updated on what my friends, acquaintances and former students are doing. LinkedIn is the professional face I present to the world, Twitter (now X) is a concise way to stay connected and YouTube is a major source of entertainment. Computers have changed our life for ever. At a basic level these are based on the flow of electrons through circuits and on the pioneering work in atomic physics done at the start of the twentieth century.
The last three decades have seen developments and changes at unimaginable speed. Who knows what the next three will bring? Will progress continue at an ever-accelerating pace or will we eventually hit a roadblock? We may have to wait for Father Time to provide the answers!
