A new phrase has crept into technology conversations, and it has started arriving in ours from business owners too: "vibe coding". The idea is intoxicating. You describe what you want in plain English, "build me an app that lets my drivers log their deliveries and photograph the proof", and an AI writes the software. No developer, no lengthy spec, no invoice with a decimal point in a frightening place. Just vibes, and a working app.
Like most intoxicating things, it is partly true, partly dangerous, and entirely dependent on what you do next. AI-assisted development is genuinely one of the biggest shifts to hit software building in a decade. It is also the source of a growing pile of half-finished, unmaintainable systems that looked miraculous for a week and became a liability in a month.
We use these tools every day. They are remarkable, and they have changed how we work. So this is not a sceptic waving them off, nor an enthusiast pretending the caveats don't exist. It is the honest, from-the-workshop view of what AI-assisted development can and cannot do for your business, and how to get the upside without inheriting the mess.
What is actually happening
Strip away the term "vibe coding" and here is the real change: modern AI can turn a description of what you want into working code, quickly, and it can explain, fix and extend that code in conversation. A capable developer paired with these tools is dramatically faster than they were two years ago. The first working version of an idea, the prototype that used to take two weeks, can now appear in an afternoon.
That speed is real and it matters. It means ideas can be tested cheaply before anyone commits serious money. It means the boring, repetitive parts of building software, the plumbing that every app needs, get written in minutes instead of days. For a business, that is faster answers to "would this even work?" and a lower cost to find out.
AI has made writing the first version of software astonishingly cheap. It has done almost nothing to make the second, third and hundredth version, the ones you actually run your business on, any easier to get right. That gap is where the trouble lives.
Where it genuinely shines
Be clear about the wins, because they are worth having.
- Prototypes and proofs of concept. Want to see whether an idea feels right before investing? AI-assisted building is superb here. A rough, throwaway version to test with real users is now cheap enough that not testing first is the expensive mistake.
- Internal tools with low stakes. A small utility that reformats a report, a quick internal dashboard, a form that saves your admin team an hour. If it breaks, nobody's data leaks and no customer is harmed. This is a great place to let AI do the heavy lifting.
- Accelerating skilled developers. In the hands of someone who can read the code, spot the flaw and steer the tool, AI is a genuine force multiplier. The developer stays in charge; the machine does the typing.
Where the vibes run out
The trouble begins the moment "a quick app to test an idea" quietly becomes "the app the business now depends on", without anyone deciding it should. AI is brilliant at producing something that works when you demonstrate it. It is far less reliable at producing something that keeps working, safely, when real customers use it in ways nobody imagined, at volume, with money and personal data flowing through it.
The gap shows up in exactly the places a business can least afford surprises:
- Security. AI-generated code frequently looks correct and quietly leaves a door open, a way for the wrong person to see the wrong data. It won't warn you, because to the AI, and to you, the app appears to work perfectly.
- The unhappy path. AI is optimistic. It builds for the case where everything goes right. What happens when two people submit at once, the payment half-completes, or someone enters an emoji where a phone number should go? That is where real systems live or die, and it is exactly what a quick build skips.
- Maintainability. A pile of AI-generated code that nobody on your team truly understands is a system held hostage. When it needs to change, and it always needs to change, you are back to square one, except now there is a working thing you are afraid to touch.
- The 80/20 cliff. AI gets you to eighty percent of a real product with startling speed. The last twenty percent, the hardening, the edge cases, the integration with your other systems, the security, is where the genuine engineering was always going to be, and AI does not remove it. It just moves it later, and makes it more tempting to skip.
The question that keeps you out of trouble
Before you build something with AI, or pay someone who is, ask one thing: "What happens if this breaks or leaks?" If the honest answer is "we lose ten minutes and a laugh", then vibe away, move fast, enjoy it. If the answer involves customer data, money, legal exposure or a process the business cannot run without, then AI is a tool your engineering should use, not a substitute for the engineering itself. The stakes decide the standard, not the speed of the demo.
How to get the upside without the mess
The businesses getting real value from AI-assisted development are not the ones who use it most aggressively. They are the ones who are clear-eyed about which bucket each piece of software falls into.
Use AI freely for the disposable and the low-stakes. Prototypes, experiments, internal helpers. Move fast, learn cheap, throw away without regret. This is pure upside.
Insist on real engineering discipline for anything that matters. When software will hold customer data, take payments, or become something your business relies on, AI belongs inside a proper process, used by someone who reviews what it produces, tests the unhappy paths, checks the security, and can explain how the whole thing works. The AI makes that person faster. It does not replace them, and pretending it does is how the liability pile grows.
Never ship what nobody understands. The single most important rule. If no human on your side comprehends how a business-critical system works, you do not own that system, you are merely renting it from a black box, and the rent comes due at the worst possible moment.
The honest summary
AI-assisted development is a genuine leap, and any business builder who ignores it is leaving speed and savings on the table. But "the AI built it" is not a quality standard, a security guarantee, or a maintenance plan. The old truths did not get repealed; they got easier to postpone. The winners in this new world are the ones who use AI to build faster and keep the judgement about what deserves real care. Vibes get you a demo. Discipline gets you a system you can trust with your name on it.
