Picture two villages, sitting next to each other. One has a paved road going in. The other does not. Over ten years, watch what happens. The village with the road gets a school bus. It gets a mandi that traders visit. Its farmers hear the morning price of onions. Its children go to a college in the district town. The other village? It stays where it was.
Now change one word. Replace "road" with "internet." Everything else stays the same.
That is the story of BharatNet. And that is the story of what we now call Digital Public Infrastructure — DPI, for short. The two are connected, but they are not the same. One is the pipe. The other is the system that runs through the pipe. You need both. And in the last five years, India has quietly built the largest such setup in the world.
Let us sit with a chai and go through this properly. Because if you understand this one theme well, you can answer a mains question on infrastructure, on inclusive growth, on governance, on India's global standing, on data protection — all from the same base of knowledge. It travels.
