From JU to ChatGPT — What Twenty-Four Years in Communications Taught Me About the Latest "Revolution"

 

In the summer of 2002, I had no plan. I had a degree and a vague, urgent feeling that I wanted to work with words and ideas. I cleared a written exam, sat before a faculty board at Jadavpur University — alone, a little nervous — and explained why I wanted to study Mass Communications in the evening class.

That was the beginning.

learning about the newest city of my life- Kolkata. Love and Hate relationship with this city, still goes on. Newspaper writing and its craft was straightforward: find something true, make it clear, give it to people. The machines involved were a computer and a dial-up connection. I worked as a struggling reporter journalist in Kolkata, putting up in a 5X3 mess bari at Moulali, for long was getting difficult. Hated to leave the city, but 2004 had different plans for me. I moved to New Delhi. writing blogs, managing operations for a Noida based KPO Vedainformatics, with a team of ‘writers’ and super writers. learning backend coding and knowing what CMS’s are — "content writing" as it was beginning to be called. My journalist friends considered it a step sideways. I considered it a laboratory. The web was a different kind of reader: patient for structure, impatient with obscurity, completely indifferent to ego.

Over the next decade and a half, I watched every platform getting launched with its own promises. Yahoo Chat Rooms, Orkut. Facebook. Twitter. YouTube, Instagram, LinkedIn. Each one was declared a revolution and we were awed, some of friends, cringed till date. Privacy is gone. Each one (platform) was, in some way. Each one also eventually became another surface to navigate.

In July 2022, I incorporated TDC Ventures with my late father as co-director. We sat with a CA in Bhowanipore and signed the papers. Two months later, ChatGPT entered the world for public use.

I started using it in September 2022. Not experimentally. As a practitioner. I wanted to understand what it could do and what it couldn't — because that distinction would matter professionally, and quickly.

It mattered. Quickly.

Cut, 2026- Last week, Neil Patel — who has spent twenty years teaching people to rank on Google — sent me an email explaining Answer Engine Optimisation. How AI assistants now build responses from published content. How businesses whose content the engines trust will win. How AnswerThePublic can show you what questions people are asking.

It was a good email. The advice is sound.

But what struck me was the strange completion of a circle. A marketer who made his name on search algorithms is now explaining to a Kolkata-based communicator — who started in print journalism before Google Analytics existed — that the machines have changed again. The answer engines are different from the search engines. The rules have shifted.

And yet.

The thing AI engines pull from is clear, useful, well-structured content. The thing Google rewarded was clear, useful, well-structured content. The thing a good editor wanted in 2002 was clear, useful, well-structured content.

The engine is new. The job is old. People are asking questions, and during the print era, people had to wait 24 hours to get the answers. People, then would still be solving this problem – to answer people.

I think about this often: the people most rattled by AI in communications are the ones who were primarily optimising for the machine — the keyword stuffers, the listicle factories, the volume-over-value shops. They built for algorithms and the algorithm changed on them.

The ones who have been writing for people — with real perspective, real experience, real care about clarity — are finding that AI engines treat their content as source material. Because it is.

I'm not nostalgic for print journalism. I'm not mourning the old ways. I built TDC Ventures precisely because I believe lean, AI-augmented teams can now punch far above their weight class. I use AI agents, as instruments the way a journalist uses a notebook — to think faster, draft cleaner, research deeper.

But I do think the Millennial communicators — the ones who crossed from print to web to social to AI without ever having had a stable medium — have something that the pure digital natives don't quite have yet: memory of the full arc. We know what it felt like when each revolution arrived. We know what survived each one.

What survived was the same thing every time: honest work, clearly expressed.

That's the answer any engine will eventually reward. It always has been.

The Road Beneath - Barrackpore the Forgotten Twin City of Calcutta

In 1868, they buried pipes under a new road to save Calcutta from thirst. In 2026, a metro must negotiate that same past to move the city forward. First water. Now transport. The problem of today was the solution of yesterday.

In 1865, British engineers stood on the muddy northern bank of the Hooghly and faced a city in crisis. Calcutta — capital of colonial India, seat of empire east of Suez — was drinking itself sick. Its tanks were fouled, its wells contaminated, its population of four hundred thousand caught between a sacred river and the arithmetic of cholera. The solution they designed was ambitious: draw clean water from Palta, twenty-two kilometres upstream, and pipe it south along a new road built expressly for that purpose. That road was the Barrackpore Trunk Road. The pipes came first. The road followed them. What those engineers could not have imagined — and what no one in 2010 paused to appreciate — was that their solution would become someone else's problem. That the infrastructure buried beneath BT Road to save a city from thirst would, a hundred and fifty-eight years later, bring a metro line to a complete standstill.

The problem of 2010 is the solution of 1865. Calcutta did not inherit a bureaucratic delay. It inherited its own ambition.

The pipes that built the road

The Palta Water Works — now renamed the Indira Gandhi Water Treatment Plant, a renaming that tells its own story — began construction in 1865 on 482 acres of land north of the city. It was the first surface-water-based supply scheme in all of Asia. The engineers drew water from upstream precisely because the Hooghly beside the city was too compromised, too shared with the dead and the living alike.

The first pipeline was installed in 1868 at a cost of ₹6,60,000. A 42-inch cast-iron pipe, running by gravity alone, carried clean water 22 kilometres south to a reservoir at Wellington Square. For the first time in its history, Calcutta had treated drinking water. BT Road was not a road that pipes happened to run beneath. BT Road was built so the pipes could be laid.

• 1865Construction begins at Palta. Asia's first surface-water supply scheme.
• 1868First 42-inch cast-iron pipeline operational. BT Road formalised as the pipeline corridor.
• 1884A second 48-inch water main laid from Palta to Tallah by narrow-gauge tramway — infrastructure built to build infrastructure.
• 1868–1968Six further expansions. Each decade adds pipes. Each pipe adds complexity. The ground becomes its own archaeology.
• 2010Pink Line Metro, Baranagar to Barrackpore, sanctioned at ₹2,069 crore.
• 2011Project report prepared. Then silence. The pipes cannot be moved. The metro cannot go elsewhere.
• 2026RVNL and KMC reopen talks. Micro-tunneling proposed. The engineering continues.

The metro that could not move

When the Pink Line was sanctioned in 2010, it seemed straightforward: an elevated corridor running 12.5 kilometres north along BT Road, ten stations, an artery for the dense suburban sprawl between Baranagar and Barrackpore. The project report was ready by 2011. Then the engineers opened the ground and found 1868 waiting for them.

Beneath BT Road runs not one pipe but a palimpsest of pipes — 42-inch cast iron, 48-inch ductile iron, 60-inch mild steel welded, each generation of expansion layered over the last. Together they carry over a thousand million litres of water daily to more than two hundred thousand domestic connections. You cannot move them. You cannot divert them for long. Half the city would lose water while the engineers worked.

This is why the line sat sanctioned but unbuilt for fifteen years. Not laziness. Not purely politics, though politics played its role. Primarily: the inheritance of ambition. The problem was too good a solution to dismantle.

A second act of engineering

The solution being explored in 2026 is worthy of the original engineers. A new 60-inch diameter pipe, laid by micro-tunneling method — threading steel beneath the existing mains without excavating the road, without disrupting flow — will run parallel to the old 1868 corridor. Water will be staged through the new pipe, freeing the old one section by section. Only then can the metro piles be cast. Hope ECL may have the best solution. 

What the 1868 engineers did with gravity, timber scaffolding, bullock carts, and cast iron — the 2026 engineers will do with micro-TBMs, butterfly valves, and structural piles. The scale is different. The ambition is not.

On the naming of stations

There is a quieter grief running alongside the engineering one. Of the ten stations on the Pink Line, nine carry names of people rather than places. Only Baranagar — the southern terminus — retains its geography without qualification. Every other station pairs or replaces the local name with a historical figure.

These are not unworthy names. But there is a difference between honouring a person and erasing a place. When a commuter cannot find their neighbourhood on the transit map — when Khardah becomes Rishi Bankim and Talpukur becomes Anukul Thakur — something frays. Not in history books. In daily life.

01Baranagar—the one that kept its name

02Krishna Kali·Kamarhati

03Acharya Prafulla Chandra·Agarpara

04Gandhi Ashram·Panihati / Sodepur

05Sarat Chandra·Sukchar

06Rishi Bankim·Khardaha

07Dr. Rajendra Prasad·Tata Gate

08Shah Nawaz Khan·Titagarh

09Anukul Thakur·Talpukur

10Mangal Pandey·Barrackpore

There are other ways to honour the dead — a plaza, an inscription on the station wall, a library wing. The name on the transit map is the name that enters the daily vocabulary of a million commuters. Choose it with some humility toward the people who already know where they live.

First water. Now metro.

In 1868, they laid the first pipe beneath what would become BT Road, solving what felt to Calcutta like an existential crisis — clean water, the most basic right of urban life. The pipes they buried were so necessary, so deeply integrated into the city's body, that a hundred and fifty-eight years later they are still there, still flowing, still indispensable — and now, also, the main obstacle to the next great act of urban infrastructure.

The best solutions become the hardest inheritances. The pipes endured precisely because they worked. And now the engineers of 2026 must negotiate not with failure but with remarkable, durable, inconvenient success.

The Pink Line will eventually be built. The commuters of Kamarhati, Khardah, Panihati, and Barrackpore will board trains above the same corridor that once delivered clean water to their great-grandparents. Above the road built for the pipes, still flowing underneath.

First water. Now metro. The line beneath the line beneath the line.

The Summer Before Search Changed Forever - Google Vs Artificial Intelligence

                                       The summer of 2022 feels strangely distant now.

I had just stepped away from my role in the pharmaceutical sector for family reasons. Like many professionals at a crossroads, I decided to bet on experience. Along with my late father, Dr. Paresh Chandra Das — who became my co-director — we sat with a Chartered Accountant in Bhowanipore, Kolkata, and formally incorporated TDC Ventures Pvt. Ltd. on 14 July 2022.

The idea was simple: build a consulting-led marketing venture rooted in two decades of experience across content, branding, digital communication, and business growth.

Fortune favoured the beginning.

Soon after launch, I secured a content mandate with a Delhi-based startup. The requirement was ambitious — nearly 10,000 words of original content every week. Blogs, health articles, press releases, news features, lifestyle pieces — scale mattered. I built a small team of six writers, streamlined workflows, and within months, we were delivering high-volume content consistently.

For a bootstrapped founder, momentum had arrived.

Then something changed.

In late 2022, ChatGPT was released for public use.

At first, many of us in marketing saw it as another productivity tool — perhaps useful for ideation or support. Few realised we were witnessing the beginning of a fundamental shift in how information itself would be created, discovered, and consumed.

Within months, the content economy began changing rapidly. Projects slowed. Expectations shifted. Cost structures changed. Businesses started asking new questions.

The old equation of digital marketing — write more, rank more, publish more — suddenly looked fragile.

The contract that once sustained my early venture disappeared.

What followed was not resistance, but introspection.

Four years later, I can say this with conviction: artificial intelligence has fundamentally altered how people search for, process, and trust information — not only in marketing, but across healthcare, law, finance, education, governance, energy, and everyday life itself.

I still remember the feeling of opening ChatGPT’s free version for the first time.

It reminded me of seeing Google in the late 1990s.

That same quiet feeling:

Something important has just changed.

And most people do not yet realise how big the shift will be. Published on Medium - https://medium.com/p/1bad2b00e987?postPublishedType=initial

Can Online Classes Replace Traditional Classes?

 The debate over digital versus physical classrooms has intensified significantly in recent years. While technology is an inevitable part of modern life, the consensus remains that online learning cannot fully replace traditional classes. As the saying goes, "You cannot learn swimming in a classroom"; similarly, the depth of a traditional education involves nuances that a screen simply cannot capture.

While e-learning serves as a powerful tool for accessibility, several critical factors highlight why the physical classroom remains the gold standard for education.

---

1. The Necessity of Hands-On Experience

Not every topic is suitable for a digital interface. While you can learn the history of a subject or government guidelines online, complex practical skills—such as flying an airplane, performing surgery, or playing competitive sports—demand a physical environment. Practical knowledge is gained through hands-on endeavors that virtual simulators can only approximate, but never fully replicate.

2. The "Digital Divide" and Technical Barriers

Online education relies heavily on consistent infrastructure.

• Accessibility: Students without reliable internet or modern hardware struggle to participate, widening the gap between different income brackets.

• Technical Fatigue: Overdependence on technology means that a software glitch or hardware malfunction can bring a lesson to a standstill.

• Tech Literacy: Not all students or teachers are "tech-savvy." If the platform becomes a burden rather than a bridge, the quality of education suffers.

3. Social Interaction and Networking

Traditional classrooms are hubs for lively discussions and immediate feedback.

• Human Connection: The mentorship and "filtered knowledge" provided by an experienced teacher in person offer a level of personal care that algorithms cannot match.

• Networking: In higher education, the opportunity to network with peers, faculty, and industry leaders is vital for career growth—a benefit that is largely diminished in a remote setting.

4. Discipline and Distraction

Without the physical presence of a faculty member and the social pressure of a classroom environment, the chances of distraction are high. Online learning requires a level of self-motivation and time management that many students, particularly younger ones, have not yet developed. This often leads to procrastination and missed deadlines.

5. Credibility and Quality Control

The rise of online platforms has seen a surge in non-accredited programs and "scam operators." This can sometimes lead to the questionable credibility of digital degrees in the eyes of prospective employers. Furthermore, even the best instructors may find their teaching effectiveness diluted by the limitations of digital delivery and design.

---

Conclusion

Online learning should be viewed as a complement and extension of classical education, rather than a replacement. While digital tools provide excellent support for theory and flexibility, they cannot replace the human relationships, physical practice, and social development that occur within a traditional school environment. For a truly holistic education, the physical classroom remains indispensable.
