Firstly, I think the areas Indian startups need to work on need not be just e-retail but also include :
1. Electricity power source which will allow decentralized, portable, scalable, application-specific source. Example is the NDB ( Nano Diamond Battery ) company in USA that is devising a prototype of that name and which uses radioactive Carbon-14 material which is waste from nuclear fission reactors. Readers can go the company's
website to know more but I will just mention that the applications range from heart pacemaker to spacecraft.
2. Building subsystems for Vertical Farming and Urban Farming that include sensors, lighting, computers, irrigation lines and hydroponics elements.
3. Cheap 3D Printers that can print metals, plastics, houses and even food. These should be cheap enough to be deployed at neighborhood level as per application.
4. Fabrication plants for microprocessor, memory and circuit boards. And this would require investment support from the government.
5. Universal carrier space rockets that can carry cargo or a crewed spaceship that can carry 100 people like the SpaceX Starship but which can also be spun-up in space to create artificial gravity and also provide comfortable room in addition to anti-radiation protection. There are currently three private Indian companies which are working on developing small-satellite launch rockets : Skyroot Aerospace, Agnikul Cosmos and Bellatrix Aerospace.
Secondly, to achieve the above, Indian students and professionals and their families should look at making a career not in traditional roles like in IT / ITES, MBA etc but be open to work in roles that include the above five areas.
