Summary
David Ondrej interviews Preston Baller, founding engineer at AMP (AMP Frontier Corporation) and author of widely-read Go programming books, for a deep dive into what agentic engineering actually looks like in practice at a company built from the ground up around AI coding agents. The conversation centers on how AMP has repeatedly killed its own features — including its VS Code extension — to stay ahead of the rapidly shifting frontier, and why the willingness to shed weight is itself a competitive moat.
Baller shares a concrete philosophy for the agentic era: backlogs are becoming obsolete when an agent can fix a bug in ten minutes with full context; software ’emacification’ is underway as developers fork and remix open-source tools using Claude Code, Codex, and Cursor rather than contributing generalized changes upstream; and the question for every new codebase is no longer how to ship features but how to make the repository agent-friendly. He illustrates this with a specific example — forking a diff viewer called Hunk, adding a custom theme and sidebar features via an embedded agent, and never contributing back because the customization was too personal to generalize.
The episode also covers why 99% of software taste still comes from human judgment even when 99% of code is written by AI, the risk of agents touching production databases without proper row-level security policies, and how AMP decides which models to route at which capability tiers across Claude, GPT, and GLM.
