Did you know every night, 20 crore Indians go to sleep hungry because they don’t have food to eat?
Point is, in a country where millions of people die every year due to poverty and hunger, even thinking about IoT in the mainstream is blatantly brutal. Instead of focusing on making homes cutting-edge, government and organizations must work to feed the poor and build them homes in the first place.
But anyway… coming to your exact question….
Internet of Things won’t be in the mainstream in India for the next 10 to 15 years. Admittedly, the government has taken the initiatives of 100 smart cities. And it is expected that we’re going to see evident result from 2022 onwards. But, call me skeptic, it is highly unlikely. It would take anywhere around 10 years till we see the idea of smart city coming into shape in a couple of places.
Unless we see more of smart cities and a fast transition of rural population into urban, IoT will have only a handful of fans, which are basically the high-net worth individuals.
So yeah, in short, we have a very long way to go.
