Mike Vizard talks with Tim Lewis, Co-Founder and CEO of tea.xyz, about how AI-driven vulnerability discovery is intensifying pressure on open source maintainers. Lewis explains why unpaid maintainers face a new wave of agentic pull requests, supply chain threats and validation costs that existing funding models were never designed to absorb. The conversation also covers maintainer burnout, signed commits, provenance, decentralized incentives, AI-assisted security, open source sustainability and why enterprises that depend on community software need to help fund its resilience.
