AI coding tools have become remarkably good. Describe what you want and you can get a working page, a form or even a small app back in seconds. It is fair to wonder whether you still need a developer at all. The honest answer is yes, and the reasons matter more as these tools get more popular.
The first is security. AI writes code that looks right, and often is right, but it learns from a huge amount of public code, including code that was careless or out of date. It can leave a form open to abuse, skip checking what a visitor types in, or suggest a software package that is old, unmaintained or simply does not exist. It does this confidently, with no warning that anything is wrong.
A developer reads that code with suspicion. They ask what happens if someone sends something unexpected, who can see this data, and what an attacker would try first. That mindset comes from experience of how real sites get broken into, and it is not something a tool brings to the job unless somebody thinks to ask.
The second is judgement. Building a site is a long series of trade-offs: speed against cost, simplicity against flexibility, what to build now and what to leave for later. An architect weighs those against your actual business, your budget and where you hope to be in three years. AI answers the question you asked. It does not know which question you should have asked.
Then there is accountability. If a site leaks customer details or breaks the law on privacy or accessibility, the responsibility sits with the business, not the tool. Someone has to understand how the whole thing fits together, make decisions they can explain, and stand behind them when something goes wrong.
None of this means AI is the enemy. I use it myself for drafts, repetitive tasks and quick ideas, and it saves real time. But everything it produces is checked, tested and tidied by a person before it goes near a live site. Think of it as a quick assistant, not the person in charge.
The practical result is that the work is shifting, not disappearing. Less time goes on typing out routine code, and more on design, security, testing and making sure the finished site does what your business needs. Those are exactly the parts that are hardest to automate.
If you have a site, or a tool someone built with AI, and you are not sure it has been properly checked, I am happy to take a look. It is a quick way to find out whether it is safe, sensible and built to last.
