Kent Beck Goes Live on Substack
Published on 30.03.2026
Kent Beck Is Live on Substack: "Live with Kent Beck"
TLDR: Substack sent a live stream notification alerting subscribers that Kent Beck — author of "Test-Driven Development: By Example" and the originator of Extreme Programming — was broadcasting a live session. The email contained no additional editorial content beyond the notification itself.
Summary: Kent Beck is one of those names that shows up at the foundation of nearly every serious conversation about software quality, sustainable pace, and developer practices. He co-authored the Agile Manifesto, invented the concept of test-driven development as a disciplined methodology, and gave the industry Extreme Programming at a time when "programming methodology" was largely synonymous with waterfall diagrams and long specification documents. The fact that he continues to engage with the developer community through live streaming in 2026 says something — though whether the medium of a Substack live stream is the most effective vehicle for his ideas is a fair question worth asking.
Live streaming is an interesting choice for someone whose influence has historically come through books, papers, and conference talks that reward careful reading and re-reading. The conversational format of a live stream can surface genuine thinking-in-progress, which has real value, but it also trades away the precision that made works like "TDD: By Example" so durable. There is a difference between Kent Beck thinking out loud and Kent Beck making a considered argument, and live formats tend to blur that line.
The notification itself carries no article text, no topic description, and no agenda for the session. We know it happened and that it was titled "Live with Kent Beck" — which tells us nothing about what he discussed. For followers who care about his current thinking on software design, AI-assisted development, or whether TDD still makes sense in a world where language models can generate passing tests on demand, the archive of the stream would be where the actual content lives.
What remains genuinely interesting is why Beck is on Substack at all. The platform has become a serious home for long-form technical writing, and his presence there — whether through live streams or written posts — suggests that the conversation around fundamental software craftsmanship is still alive and finding new audiences. Whether those audiences are getting the same depth of thinking that his books delivered is the real question.
Key takeaways:
- This newsletter item was a live stream notification, not an article — substantive content lives in the stream archive
- Kent Beck remains active in the developer community in 2026, publishing and broadcasting through Substack
- The live stream format raises legitimate questions about depth vs. accessibility for technical ideas
- Beck's continued relevance points to unresolved tensions in software practice, especially as AI changes what "writing code" means
Why do I care: From a senior engineering perspective, Kent Beck's ongoing public presence matters because TDD, refactoring, and the small-steps philosophy he championed are under real pressure right now — not from lack of merit, but from AI code generation tools that change the economics of test-first development. Whether Beck is engaging with that tension directly is worth knowing. A live stream notification without context is the least informative possible way to find out, but the fact that developers are still tuning in to watch him think out loud tells you that the foundational questions he raised have not been settled.
