This is a submission for the Google Cloud NEXT Writing Challenge => I Was Watching NEXT '26… And Something Felt Off 👀 I was watching the Google Cloud NEXT '26 livestream like every other de. Everyone was hyped about: 👉 TPUs 👉 Gemini 👉 AI agents Then Google dropped A2A (Agent-to-Agent protocol). And my first reaction was: 👉 “Wait… didn’t the industry already start moving toward MCP?” Because just days before that: 👉 OpenAI adopted MCP 👉 Anthropic was already pushing it Now suddenly - Google enters with A2A.
