Tom Tunguz published 12 predictions for 2026, and three dominate this episode: agent-first software design, vector databases becoming infrastructure-layer defaults, and AI compute costs potentially exceeding human labor costs per task. That last one is not a hypothetical. It is a trajectory.
Rob Pike got targeted by an AI-generated 'act of kindness', a form of automated slop documented by Simon Willison. The episode uses that incident as a entry point into a harder question: GitHub's consolidation of open source identity, reputation, and infrastructure into a single Microsoft-controlled platform. Ploum's January 2025 piece argues this monoculture is actively damaging the ecosystem, not just inconvenient.
Mat Ryer joins Jerod Santo and Adam Stacoviak for this Changelog Friends episode. Read the Tunguz predictions post and the Ploum piece before listening. The conversation earns its runtime because it connects those sources rather than just summarizing them.
