Infosys Co-founder Nandan Nilekani, whose colleague Narayana Murthy sparked 70-hour workweek debate, said he spends 20% of his time as Infosys' Non-executive Chairman. "I spend another 30-40% of my time on stuff like DPI (digital public infrastructure), artificial intelligence, and other technology initiatives," the 69-year-old billionaire said. Nilekani added, "Rest of the time, I do nothing."
