NEW DELHI: At the India AI Impact Summit 2026 which concluded this week, the buzz wasn’t just about algorithms; it was also about an aroma. While the world’s tech elite gathered at Bharat Mandapam to debate the “Fifth Industrial Revolution,” India leveraged the opportunity to showcase its impressive Digital Public Infrastructure (DPI) as a tangible, lifestyle experience.A big viral moment, in fact, happened away from the stage, at the Bharat GI Coffee Experience Centre. Union minister Ashwini Vaishnaw’s Instagram feed became a digital gallery of this strategy, featuring a reel captionedread: “Bharat GI, UPI, and AI: We are becoming a strong product nation.”The post showed a high-tech “coffee stall” where Google CEO Sundar Pichai was seen sampling GI-tagged Malabar Arabica, paying via UPI and discussing AI-driven supply chains. The linkage between a cup of coffee and the Unified Payments Interface (UPI and Geographical Indications (GI) demonstrated that DPI is the “secret sauce” that allows AI to scale from hi-tech labs to local street stalls, said an one of the organiser.This “DPI-first” philosophy found its loudest international echo in Brazil , During the summit, Brazil’s President Lula da Silva and PM Narendra Modi advanced a landmark bilateral partnership. Brazil is not just looking at India’s code but its philosophy; The two nations are working to link India’s UPI with Brazil’s Pix and establishing a Centre of Excellence for DPI in Brazil.
