AI Daily Brief — 21 February 2026

A wind-down Saturday for the India AI Impact Summit. As of today the New Delhi Declaration on AI Impact stands endorsed by 88 countries and international organisations — including the US, Russia, China, EU, UK, France, Israel, Canada, Saudi Arabia and Singapore — with three more (Bangladesh, Costa Rica, Guatemala) joining in the days after to take the total to 91. CNBC publishes its on-the-ground post-mortem: long queues, overcrowded rooms, conflicting security instructions, an exhibitor eviction during Modi’s visit and Bill Gates’s last-minute keynote cancellation — set against more than $200B in pledged AI-infrastructure investment.
