Vibe Coding Is Not Engineering
Coders are fighting over whether AI is a shortcut, a scam, or just the new intern
TLDR: The article argues that AI can quickly produce code, but it often skips the important planning that keeps apps safe and usable in real life. In the comments, people split between cheering that warning, mocking “gatekeeping” developers, and joking that the future might be “vibe engineering” instead.
The article’s big warning is basically this: getting a chatbot to spit out working code is not the same thing as building something safe and reliable. The author says AI can whip up a flashy login page in seconds, but it won’t stop to ask the boring-but-crucial questions, like whether two people can share one email address, how password resets should work, or what happens when things go wrong. In plain English: a demo can look great right up until real people start using it and the whole thing faceplants.
But the comment section? That’s where the real fireworks are. One camp was fully on board with the warning, with people basically saying, “Sure, AI can write stuff, but that doesn’t magically make it good.” Another camp came in swinging at old-school software culture, accusing developers of using “engineering” as a fancy shield for gatekeeping and nitpicking. That sparked the spiciest clash: is this a serious caution about quality, or just another round of tech people defending their turf?
Then came the plot twist: the self-described “vibe engineering” crowd. Their argument was less “AI does everything” and more “humans set the rules, AI does the grunt work.” It’s the thread’s funniest rebrand and maybe its most revealing one. Everyone agrees AI is fast. The brawl is over whether speed without deep thinking is a superpower, a disaster, or—classic internet compromise—just another tool with a wildly overconfident fan club.
Key Points
- •The article argues that AI-generated "vibe coding" can produce code quickly but does not replace the engineering work required to build coherent production systems.
- •It lists pre-coding engineering tasks including problem framing, requirements engineering, system modelling, architectural design, non-functional requirements, risk identification, interface design, and planning.
- •The article says LLMs skip critical system concerns such as invariants, identity, constraints, failure modes, sequencing, state transitions, contracts, boundaries, and error handling.
- •It argues that when those decisions are missing, teams encounter feature conflicts, unpredictable system state, fragile deployments, unclear errors, and difficulty extending the product.
- •A demo example involving Python, Flask, and SQLite is used to show that generated login code may work technically while omitting key requirements like unique emails, verification, password resets, roles, and security design.
