AI Coding Tools Increase Security Risks and Erode Skills

Anand Naidu is a veteran of the software development world who has witnessed the industry transition from the manual “whiteboard era” to the modern “copilot era.” As a resident expert in both frontend and backend systems, Anand has a front-row seat to how artificial intelligence is reshuffling the deck for engineering teams across the globe. He brings a pragmatic perspective to the table, balancing the undeniable productivity gains of AI with the cold, hard data regarding security risks and the erosion of foundational skills. Our conversation focuses on the friction between rapid AI adoption and the long-term health of codebases, exploring why “working code” is no longer a high enough bar for modern enterprise standards.

We discuss the mounting evidence that AI-generated code is frequently a house of cards, built on shaky security foundations and a declining grasp of basic logic among early-career engineers. Our conversation touches on the specific technical vulnerabilities that AI struggles to identify—such as cross-site scripting and log injection—and how companies must recalibrate their hiring and training processes to prioritize cognitive reasoning over raw output. Anand provides a deep dive into the psychological and professional gap between junior developers who feel empowered by AI and the senior leaders who see a looming crisis in code quality and system maintainability.

The industry is currently obsessed with the speed that AI coding assistants provide, but you’ve often cautioned that this speed might be an illusion. Looking at the recent story of a fintech company where a “perfect” authentication feature failed a security audit three weeks later, how should teams redefine what “successful code” actually looks like?

We have to move away from the idea that code is successful just because it passes a test suite in a staging environment. In that fintech case, the logic worked perfectly for the happy path, but the AI-generated code completely bypassed a permission check in an edge case that no human had thought to verify. This is the “hidden cost” in action; the developer felt the thrill of finishing early, but they weren’t actually “done” because they didn’t understand the underlying security architecture enough to spot the omission. Successful code shouldn’t just be measured by its functional output, but by its transparency and the developer’s ability to explain every single line of logic. If a junior dev can’t tell you exactly why a specific permission check is placed where it is, that code is a liability waiting to happen, regardless of how fast it was “written.”

The data regarding security is quite startling, with studies showing that 45% of AI-generated code samples contain at least one OWASP Top 10 vulnerability. Why do you think AI models are hitting a plateau when it comes to fixing these security flaws, even as the models themselves get larger?

It’s a classic case of pattern matching versus actual understanding. Veracode’s testing has shown that while models can handle common patterns like SQL injection because they’ve seen millions of examples, they perform very poorly on context-dependent flaws like log injection and cross-site scripting. These aren’t just snippets of code you can swap out; they require a deep understanding of how data flows through a specific, unique system architecture. The 45% failure rate has stayed stubbornly flat since 2025 because the models aren’t “thinking”—they are predicting the next likely character based on a dataset that, frankly, contains a lot of insecure human code. When you realize that AI-generated pull requests have a 2.74x higher vulnerability density than human-written ones, you start to see that the AI is effectively amplifying our own worst coding habits at a massive scale.

There seems to be a massive disconnect between how junior developers and senior engineers perceive the impact of AI, with 85% of juniors feeling more capable while only 16% of seniors agree. What is happening beneath the surface of that perception gap?

That gap is one of the most dangerous trends in our industry right now. A junior developer using an AI tool feels a rush of dopamine because they can move from a blank screen to a “working” solution in seconds, which creates a false sense of mastery. However, the 2026 BairesDev survey of over 1,500 developers across 77 countries confirms what many of us suspected: that confidence isn’t backed by comprehension. Seniors look at that same code and see a lack of structural integrity and a fundamental misunderstanding of how the pieces fit together. It’s a sensory mismatch—the junior feels like they are flying, but the senior sees that they’ve forgotten how to walk, and eventually, everyone has to land.

The Anthropic study highlighted a significant “learning tax” when juniors delegate code generation to AI, showing a drop in comprehension scores from 65% down to below 40%. From your perspective, why does delegating the writing of code lead to such a steep decline in debugging skills specifically?

Debugging is essentially a detective story where you have to understand the “why” behind the “how,” and if you didn’t write the code, you lose the mental map of its creation. In the Anthropic study, the group that used AI for conceptual questions scored 65% or higher because they were using the tool to sharpen their own logic. But the group that let the AI write the code plummeted below 40%, effectively failing the comprehension test because they never engaged their own cognitive muscles. The most telling part of that study was that the AI-assisted group only saved about two minutes on average, which is statistically insignificant. We are effectively trading away a massive chunk of our intellectual growth—a two-letter-grade gap—for a measly 120 seconds of saved time, which is a disastrously poor bargain for any career.

In languages like Java, which power the backbone of global finance and enterprise systems, why is the risk of AI-reliance even more pronounced than in other environments?

Java is a language built on strict structures—object-oriented models, rigorous exception handling, and complex memory management—and it’s designed for code that is meant to live for a decade or more. When a junior developer skips the fundamentals of Java because they are relying on a prompt, they are missing the very guardrails that make Java reliable for high-stakes environments like Android development or backend infrastructure. If the AI hallucinates a memory management approach or skips a catch block, the result isn’t just a minor bug; it’s a systemic vulnerability that might not be caught for years. You cannot evaluate AI-generated Java effectively if you don’t understand the JVM (Java Virtual Machine) or how classes interact, and per the data, that lack of understanding leads to security-sensitive logic being wrong nearly half the time.

Technical interviews are starting to change, moving away from “write this function” toward “explain this output.” How should a candidate prepare for this new era where their ability to reason about code is more important than their ability to produce it?

The signal has shifted from “can you code” to “can you reason,” and candidates need to adjust their practice accordingly. Instead of just grinding out solutions on LeetCode with an AI assistant open in another tab, they should spend time taking AI-generated snippets and trying to break them or find the hidden vulnerabilities. Interviewers are now looking for that “aha!” moment where a candidate spots a log injection flaw or explains why a certain object structure is inefficient for memory. If I’m hiring, I want to see you struggle with the “why” and demonstrate that you don’t just trust the tool blindly. The goal is to prove that you are the pilot and the AI is just the navigation system—you need to show you can still fly the plane if the GPS goes dark.

Engineering leaders are now being told to treat AI-assisted code review as its own distinct category. What does that look like in practice, and how does it change the daily workflow of a senior developer?

It requires a total shift in mindset where you treat AI-generated code with a much higher degree of skepticism than you would a trusted colleague’s work. Standard review checklists aren’t enough because AI tends to fail in ways that humans don’t—it might produce syntactically perfect code that is logically hollow or structurally unsafe. Reviewers need to be trained specifically to look for those context-dependent flaws, like the 2.74x higher density of vulnerabilities we see in AI pull requests. Practically, this means slowing down the review process, not speeding it up, and using those reviews as teaching moments to show juniors where the AI’s “logic” fell apart. It’s about building a culture where “the AI wrote it” is never an acceptable excuse for a security flaw.

What is your forecast for the future of developer education as these AI tools become even more embedded in the coding process?

I believe we are going to see a “renaissance of the fundamentals” where the most valuable developers aren’t the ones who can prompt the fastest, but the ones who can audit the most deeply. We will likely see a split in the market: a tier of “prompt engineers” who produce high volumes of low-quality, high-risk code, and an elite tier of “systems architects” who use AI as a high-speed chisel but still understand the grain of the wood. Organizations will realize that skipping a structured, fundamentals-first course—like a deep dive into Java basics—is just deferring a massive technical debt that will eventually be paid in the form of a 45% vulnerability rate. My forecast is that within five years, the “senior” title will be reserved exclusively for those who can demonstrate they don’t need the AI to solve the problem, even if they use it to finish the task. We are moving toward a world where human judgment is the only true bottleneck, and those who invest in that judgment now will be the only ones left standing when the novelty of AI speed wears off.
