Peter Thoeny @peterthoeny.bsky.social · 24/09/2026Gen-AI Vibe #21: I Stopped Reviewing the Code For years I reviewed every line of generated code. I do not anymore. That is not giving up on quality. I stopped reading every line. I did not stop checking. The architecture and the design work upstream are what make it possible. bit.ly/4h8CX3X 020 2
Peter Thoeny @peterthoeny.bsky.social · 19/08/2026Gen-AI Vibe #20: How to Add an AI Agent to an Existing Web App Four days, 100+ files, 13,700 lines. Adding an agent to a mature app with permissions, undo, and real-time sync is a different job than building a chatbot. Eleven points. Notice how little of it is about the model. bit.ly/3SH33l2 110 1

Peter Thoeny @peterthoeny.bsky.social · 13/08/2026Gen-AI Vibe #19: Who Wrote This? How much of my code is written by AI? Line by line, 95-99%. But coding is ~20% of shipping a feature. Both numbers are true. They measure different things. Which matters when a client concludes they're paying you for the 1%. Read & subscribe: bit.ly/45kXY4L 010 1
Peter Thoeny @peterthoeny.bsky.social · 06/08/2026Gen-AI Vibe #18: Security Isn't in the 90% Mozilla fixed 423 Firefox security bugs in April 2026. The 2025 monthly average was 21. Firefox is one of the most audited codebases on earth. The bugs were there for 20 years. Nobody could see them, until a frontier model looked. bit.ly/459LFIu 030 3
Peter Thoeny @peterthoeny.bsky.social · 31/07/2026Gen-AI Vibe #17: Code Is Cheap, Shipping Isn't AI coding agents produce 17.3x more code, and 1.3x more shipped software. 100,000 GitHub devs, NBER paper. The gain leaks at review, integration, testing. Code generation was never the slow part. How I try to close the gap: bit.ly/4h0DyoH 140 4
Peter Thoeny @peterthoeny.bsky.social · 23/07/2026Gen-AI Vibe #16: Nothing to FIXME I finished a feature and went looking for the FIXMEs to clean up. There were none, rare for AI-generated code. I used the expensive model for every phase. It went great. Which seems to contradict everything I've said about conserving tokens. bit.ly/3Tiusd1 010 1

Peter Thoeny @peterthoeny.bsky.social · 10/07/2026Gen-AI Vibe #14: The Bottleneck Moved Code is no longer the bottleneck. True, but it's half a sentence. A bottleneck never disappears. It moves. And a randomized trial found developers 19% slower with AI while feeling 24% faster. Why I gain anyway: bit.ly/4fakou0 031 3
Peter Thoeny @peterthoeny.bsky.social · 02/07/2026Gen-AI Vibe #13: Chasing Ikigai I code much less now, mostly delegating to an AI agent. But I love coding. This raised a question: if the machine does the part I get up in the morning for, what am I getting up for? It's Ikigai. And it's darker than the Western version. bit.ly/4eWrxht #VibeCoding 240 4
Peter Thoeny @peterthoeny.bsky.social · 25/06/2026Gen-AI Vibe #12: The One-Person Powerhouse With AI agents I produce like a team of 7-8 engineers. The barrier to starting a business has collapsed, but winning hasn't. The real divide: companies that improve the old model vs. those that rebuild around AI. The bottleneck is mindset. bit.ly/4eqtxPW 010 1
Peter Thoeny @peterthoeny.bsky.social · 18/06/2026Gen-AI Vibe #11: Code Quality & Blast Radius I used to deliver near-zero-bug code. Now the AI writes it, I review 30-80%, productivity is up 10x, and I ship bugs. Agents that delete production databases and plow ahead where a human would hesitate? That's blast radius.

Peter Thoeny @peterthoeny.bsky.social · 11/06/2026## Gen-AI Vibe #10: Cognitive Offloading New research on AI and thinking: the curve is U-shaped. Scattered AI use (a snippet here, a fix there) is worse than no AI at all. Benefits only kick in when you delegate entire categories of work and reinvest the freed capacity in judgment. bit.ly/4eCP5J2 020 2

Peter Thoeny @peterthoeny.bsky.social · 04/06/2026Gen-AI Vibe #9: Stay Human Loneliness. Bossiness. The yes-man effect. The slow atrophy of analytic muscles. Four quiet shifts I've noticed in myself from spending hours a day with AI agents. None of them are reasons to stop. All of them are reasons to stay aware. Article: bit.ly/4eodRfT 030 3

Peter Thoeny @peterthoeny.bsky.social · 27/05/2026Gen-AI Vibe #8: The All-You-Can-Eat Buffet Is Closing Coding with AI is changing from an all-you-can-eat buffet metered use. What this means in practice: which model to use for design vs. implementation vs. testing, why a low-hallucination model is worth paying for. Article: bit.ly/4nTf6Hf 130 3
Peter Thoeny @peterthoeny.bsky.social · 20/05/2026Gen-AI Vibe #7: Don't Make Me Think Steve Krug published a small book called Don't Make Me Think. It is about web usability -- good software should let users accomplish their tasks without too much thinking. I asking the AI agent to use this principle when writing code.

Peter Thoeny @peterthoeny.bsky.social · 13/05/2026Gen-AI Vibe #6: When Software Becomes Cheap - AI has collapsed the cost of producing code, the result will be a flood of it. - A race to the bottom that already played out in photography. - AI is democratizing software, especially for open source.

Peter Thoeny @peterthoeny.bsky.social · 06/05/2026Gen-AI Vibe #5: Putting Guardrails on Your AI Teammate The productivity gains are real for software development, but only if you invest in keeping the AI agent aligned with rules.
