My fireside chat about agentic engineering at the Pragmatic Summit
Summary
This talk covers how software developers are adopting AI coding agents, from simple question-asking with ChatGPT to agents writing entire programs. The speaker emphasizes that trusting AI output (like Claude Opus) requires pairing it with test-driven development (TDD, a practice where you write tests before the actual code) and manual testing, since automated tests alone don't guarantee the software will actually run correctly.
