Has AI Finally Made Computers Useful for Everyone? | Chris DiBona, Microsoft

What happens when the people who could never fully use computers finally can? From open source strategy to agentic interfaces and developer tooling, almost every assumption about who gets to build with technology is being rewritten. In the third episode of Choose Your Stack, recorded at the MCP Dev Summit in New York City, Ryo Koyama sits down with Chris DiBona, Vice President from the Office of the CTO at Microsoft, to explore what decades of open source taught us about developer ecosystems and why those lessons matter more than ever in the age of AI agents. Chris breaks down why MCP succeeded where other protocols failed, why the line between programmer and non-programmer is disappearing, and why the real challenge for the industry is building AI tools that are personalizable and secure for billions of people who do not all look or think the same. 0:00 Intro 0:21 Microsoft’s open source contributions 2:07 The excitement behind MCP 5:22 CLI vs MCP 8:04 The democratization of coding 11:23 Chris’s Hong Kong cabinet AI project 14:04 Agents as toil reducers 15:19 The future of developer relations 17:04 Open source and LLM training 19:40 Hot take: the industry doesn’t know real programmers 21:08 Personalization at a billion-user scale The computer industry has been making the same promise for decades.
