AI Definitions: Vibe Coding

Vibe Coding – An LLM generates code that meets the specifications stated in the user's prompt. This is not the same as software development, where the user reviews the AI coding and can explain it. This type of coding uses natural language to communicate desired outcomes. Vibe coding platforms would include Claude Artifacts, Creator Hunter, and Cursor. While the goal is a finished product, in practice, this approach entails risks, such as hidden bugs and subtle security issues. Some degree of human oversight and refinement is still needed for most LLM-generated code outcomes to become production-ready.

A way to create finished, bug-free programs without human intervention

Users of Claude Code, Anthropic’s software-writing AI system, recently discovered a way to create finished, bug-free programs without human intervention. The trick: Write a small program that asks the AI, over and over again, to improve the code it has already written. Named the Ralph Wiggum technique, after the dimwitted but persistently optimistic “Simpsons” character, this simple trick is effective at forcing Claude Code to solve problems on its own. - Wall Street Journal

The Vibe-Coding Guardrails

Jason Lemkin, a startup founder, embarked on a very public experiment in AI-assisted development to build a networking application. Over the course of a week, euphoria turned to disaster. Lemkin tweeted that the AI agent had caused a catastrophic failure: it had gone rogue and wiped his production database entirely, despite explicit instructions to freeze all code modifications. The incident was peak vibe-coding, crystallizing growing concerns that the speed and apparent ease of AI-generated code had seduced builders into abandoning the very guardrails that prevent such disasters. Despite the recent gloom, I’m actually optimistic about LLMs coding more broadly. We just have to use the tools differently. - Michael Li, Harvard Business Review

AI Supervision

One coding team spent 3 days fixing what should have been a 2-hour problem. They had "saved" time by having AI generate the initial implementation. But when it broke, they lost 70 hours trying to understand code they had never built themselves. The time you save upfront gets charged back with interest later. The best teams avoid this because the human engineer actually understands the code. They shaped it. They made the key decisions. The AI just handled the mechanical work of typing it out. The new constraint is: "Can we understand the code we're writing fast enough to keep moving?" Treat code review as a comprehension verification step, not just a bug-catching exercise. - Paul Sangle-Ferriere

The jobs of Experienced Coders

The combination of higher salaries and a reluctance to embrace A.I. was likely to put the jobs of experienced coders at risk. “How you decrease cost is not by firing the cheapest employees you have. You take the cheapest employee and make them worth the expensive employee. In a recent study by researchers at Microsoft and three universities, an A.I. coding assistant appeared to increase the productivity of junior developers substantially more than it increased the productivity of their more experienced colleagues.” -New York Times

Balancing Speed with Quality Coding

Speed means nothing without quality. Shipping buggy, unmaintainable code faster is a false victory – you’re just speeding towards a cliff. The best engineers will balance the two: using AI to move faster without breaking things (at least not breaking things any more than we already do!). It’s about finding that sweet spot where AI does the heavy lifting and humans ensure everything stands up properly. - Addy Osmani writing on Elevate

AI Magic & Engineering Principles

None of this is to say AI can’t write good code – it sometimes does – but rather that context, scrutiny, and expertise are required to discern good from bad. In 2025, we are essentially using a very eager but inexperienced assistant. You shouldn’t blindly trust an AI’s code without oversight. The hype of “AI magic” needs to meet the reality of software engineering principles. - Addy Osmani writing on Elevate

Unchecked AI-generated Code

Unchecked AI-generated code can massively amplify technical debt, the hidden problems that make software brittle and costly to maintain.  Many early vibe-coded projects look good on the surface (“it works, ship it!”) but hide a minefield of issues: no error handling, poor performance, questionable security practices, and logically brittle code. - Addy Osmani writing on Elevate
