Google I/O 2026 Highlights: Gemini Agent Mode and AI Mode Search Go Live

Google I/O 2026 is hailed as the 'biggest AI launch ever.' Key announcements include: Google Search fully enters AI Mode (AI answers replace blue links), Gemini 2.5 Pro supports 2 million token context, Project Astra launches as Android's built-in AI assistant, and Gemini Agent can autonomously perform complex tasks like web browsing, form filling, and ticket booking. Analysts expect this to significantly impact search traffic for Perplexity, Claude, and Baidu.
