How AI is Rewriting the Rules of Software Engineering

Artificial Intelligence is no longer a futuristic concept—it’s a practical, evolving force that is reshaping industries in real-time. One area undergoing significant transformation is software engineering.

A recent article titled “A Perspective on AI Opportunities in Software Engineering” by Bernard Murphy brought some of these shifts into focus. Drawing from a research paper published by the University of Auckland, the article explores how AI, particularly through large language models (LLMs), is influencing the software development lifecycle. It also touches on broader implications for other fields, including hardware engineering.

This blog explores key insights from the article and examines both the opportunities and risks of AI-driven development in software engineering.

The Decline of Traditional Coding Habits

StackOverflow, once the go-to platform for developers to exchange ideas and troubleshoot code, is seeing a decline in traffic. According to Murphy, this shift is largely due to the rise of LLMs like GPT-4, which can summarize user queries and provide ready-to-use code snippets without the need for browsing external links.

This signals a shift in developer behavior. Instead of synthesizing code from scratch, many now rely on retrieval-augmented generation (RAG)—an AI approach that pulls and adapts existing code snippets based on the context of the user’s prompt. As a result, platforms that were once essential for collaborative problem-solving are being sidestepped in favor of more streamlined AI-powered solutions.

GitHub Copilot and the Rise of AI-Assisted Coding

Perhaps the most striking indicator of AI's growing role in software engineering is the rapid adoption of GitHub Copilot, an AI-powered code assistant developed by Microsoft. The tool now boasts over 1.3 million paid developers across 50,000 organizations and continues to grow at an impressive 30% rate each quarter.

The takeaway is clear: AI-assisted coding is no longer an experiment—it is becoming a cornerstone of modern development workflows.

Beyond Code: AI’s Expanding Role in the Development Cycle

Before a single line of code is written, the requirement-gathering phase often becomes a bottleneck. Translating a client’s abstract needs into actionable development objectives is a complex and error-prone process. This is where AI agents show significant promise.

AI can assist in eliciting requirements interactively, resolving ambiguities, and providing scenario-based examples to better align developer understanding with client expectations. These tools can also validate requirements by highlighting inconsistencies or vague language.

Another area where AI can drive substantial value is in maintaining documentation. As software evolves, keeping documentation aligned with the latest codebase is time-consuming and often neglected. AI-powered documentation systems can track changes in real time, update technical documentation accordingly, and generate tailored views for different stakeholders—from developers and product managers to clients and end users.

Risks and Limitations of AI in Software Engineering

Despite its many benefits, AI in software development is not without drawbacks. One of the most pressing concerns is hallucination—instances where the AI confidently generates incorrect code or logic. While model accuracy is expected to improve over time, it is unlikely to reach the level of reliability offered by traditional tools like calculators, which always provide correct results.

Another growing concern is over-reliance on AI, leading to a decline in developers’ problem-solving and critical thinking skills. Without expert review, erroneous suggestions could slip through into production environments, causing costly and even catastrophic failures.

There’s also a structural concern about how the training data for these models is evolving. As more of the content used to train AI models is itself AI-generated, the quality and diversity of the codebase may stagnate. Without mechanisms to reward and highlight original human contributions, innovation may be stifled.

Mitigating the Downsides: Strategies for Safe AI Adoption

To address these challenges, one of the key recommendations is maintaining independent unit testing. Relying on AI to both write and test the code is a recipe for undetected errors. Separation of duties is fundamental to software quality assurance.

Additionally, Murphy highlights the potential of metamorphic testing—a technique that validates expected relationships between input and output, even as the implementation evolves. While finding such relationships can be difficult, AI may assist by proposing candidate invariants. However, these must still be vetted by human experts to ensure they are not artifacts of limited test scenarios.

Surprisingly, the article does not deeply explore how AI could connect requirements gathering to automated testing—a natural progression that could further streamline the development lifecycle. Nevertheless, this remains an exciting area for future exploration.

Conclusion: AI as a Partner, Not a Replacement

AI tools are poised to dramatically improve efficiency, scalability, and precision in software engineering. From writing code and maintaining documentation to helping define project requirements, the opportunities are immense. However, these gains come with responsibilities.

Engineering precision demands human oversight. AI should be viewed not as a replacement for skilled developers, but as a partner—augmenting their abilities while still requiring their judgment and expertise.

As we move forward, the goal should be to harness AI thoughtfully, maintain high standards of quality, and ensure that innovation continues to thrive through the unique insights only human engineers can provide.
