AI reshapes cities and institutions in a day-in-the-life account.

A day-in-the-life column traces how AI is moving from tools to operating systems, highlighting Mumbai's AI-planned "Third Mumbai," MIT's shift toward agent literacy, and a new Massachusetts AI Coalition and state AI rollout.

A day-in-the-life column describes how AI is moving beyond software trends to reorganize cities, institutions, education, startups, and government. The piece connects an AI-planned urban project in Maharashtra with changes at MIT and a coordinated effort in Massachusetts. It follows events across a single day — from a Venture Studio class on agents to a packed MIT startup career fair to a state announcement about an AI assistant deployment. The central idea is that places that align talent, capital, education, and public leadership will shape the next phase of AI. Key developments: - The column reports an AI-led urban plan called "Third Mumbai" (or "Mumbai 3"), and notes a planned $11 billion investment from Tata for the project. - MIT Venture Studio focused on agent systems, with examples named such as OpenClaw and Moltbook and an emphasis on agent literacy over chatbot framing. - An MIT student-led startup career fair featured 62 booths and over 1,000 registered students, signaling strong interest in AI-native companies. - The article reports a Massachusetts initiative to deploy an AI Assistant across state employees in partnership with OpenAI, with public statements from Governor Maura Healey and state officials. - The Massachusetts AI Coalition launched, with founding members, nine task forces, and plans for coordinated events and support to help start, scale, and retain AI companies in the state. - Local leaders are framing AI as a platform shift affecting healthcare, education, robotics, biotech, clean energy, and other high-impact industries. Summary: The article presents AI as a platform-level shift already affecting urban design, academic curricula, startup formation, and public administration. It reports specific initiatives — including the planned Tata investment in "Third Mumbai," MIT's agent-focused coursework, and a Massachusetts rollout of an AI assistant for state employees. The Massachusetts AI Coalition intends to organize task forces and events to support local AI company formation and growth. Further coalition activities and government deployments are reported as the next steps.
