When the co-founder of Infosys and architect of the unique identity project, Aadhaar, Nandan Nilekani, talks about disconnecting from devices, it certainly seems a bit odd. But, while believing in the transformational power of technology, he says everyone must practice digital hygiene to be effective. His new book, The Art of Bitfulness: Keeping Calm in the Digital World, which he co-authored with iSPIRT Foundation fellow Tanuj Bhojwani delves into this subject. In conversation with ET’s Surabhi Agarwal, Romit Guha and Archana Rai, he says that everyone should carve out their own rules and boundaries to get the best out of technology.
