Kolkata was once supposed to be India’s Silicon Valley, not Bengaluru.
The city had everything going for it:
Indian Statistical Institute in Kolkata ran India’s first electronic computer in the 1950s, Webel was building an electronics hub by the 1980s, and the city already had colonial‑era advantages like early electricity, telegraphs, railways and a major port backing a dense belt of elite colleges and industry.
On paper, this should have been the place where India’s tech story took off. Instead, Bengal’s politics went to war with computers.
The CPM government spent the 70s and 80s backing protests against computerisation in banks and offices because they feared computers would eliminate jobs.
The message to business was very clear:
if you bring technology here, you will face resistance.
While this fear was driving policy in Bengal, Bengaluru and Hyderabad were opening their doors to the same companies.
So the big IT parks, global tech campuses, startup activity, and serious capital flowed there, not to Kolkata.
And once that happens, it is very hard to catch up.
Regions that resist new technology suffer from what economists call “technology diffusion failure”:
early adopters keep getting compounding benefits from knowledge spillovers, while laggards fall further and further behind.
When an ecosystem settles in places like Bengaluru, network effects and skills start to lock in those advantages, and late entrants face higher costs, weaker local talent pools, and capital quietly moving elsewhere.
TMC arrived promising to correct this.
And some IT investment did come in; the state talks of around ₹14,000 crore in IT and new parks in Salt Lake and New Town.
But Bengal still did not become the first choice for large product companies or global tech hubs, because the deeper issue remained: investors had seen how politics could suddenly turn against a project.
The best example of that is Singur, where Mamata Banerjee’s agitation forced the Tata Nano plant out of Bengal.
That is exactly what can finally change now.
When Tata left Singur, Gujarat under Narendra Modi showed what a pro-industry state can do by turning the same project into a showcase at Sanand.
If the newly forming BJP government brings that same investor-friendly mindset to Bengal, the pitch to companies changes in a very practical way.
