India could be heading towards an extraordinary phase of economic expansion even as artificial intelligence, technology and regulatory changes transform the way businesses and economies operate, Tata Sons Chairman N Chandrasekaran said. Speaking as the chief guest at the convocation ceremony of Sai University, Chandrasekaran told graduating students that they were beginning their professional lives at a time of rapid global transformation. While the pace of change may create uncertainty, he said it would also generate opportunities that are difficult to foresee at present.
