As India approaches the centenary of its independence in 2047, the national vision of "Viksit Bharat" aims to transition the country into a developed, self-reliant, and sustainable economy. Central to this transformation is the democratization of Science and Technology (S&T). This paper proposes that achieving Viksit Bharat requires a paradigm shift: moving technological innovation from isolated laboratories into the everyday living rooms of its citizens. Utilizing a multidisciplinary blueprint that intersects Science, Technology, Commerce, and the Humanities, this study examines how macro-innovations translate into micro-level societal benefits. Through a detailed case study of India’s Digital Public Infrastructure (DPI)—specifically the Open Network for Digital Commerce (ONDC)—the research demonstrates the necessity of integrating technical scalability with economic viability and human-centric design. The findings indicate that future S&T policies must prioritize digital inclusivity, indigenous deeptech commercialization, and socio-cultural adaptability to realize an equitable and developed India by 2047.
