Read Blue Hat's Kai Widdeson’s guest blog on techUK’s AI Adoption Hub for their #SeizingTheAIOpportunity campaign week 2025.
Learn how AI is reshaping software development through modular code and automation.
Kai discusses the use of AI for code generation, debugging, testing, and project management, emphasising increased productivity and reduced human error. But this transformation comes with its own set of challenges.
Kai looks the risks around code reliability, ethical decision-making, and the necessity of human oversight. Ultimately, it presents AI not as a replacement for developers but as a powerful assistant that enhances efficiency and innovation in software engineering.
About techUK’s AI Adoption Hub: 2025 is the year AI becomes an integral part of everyday life, as organisations across industries prioritise embedding AI into their core strategies and operations. To help promote greater levels of responsible AI adoption, techUK will continue to work alongside its members and key stakeholders across the AI ecosystem, to demonstrate the significant benefits of this technology for both the economy and society. www.techuk.org
Artificial intelligence is rapidly changing how software is built. From writing simple functions to automating tests and debugging, AI is increasing the pace and precision of development work. AI is becoming a powerful assistant that can help teams build smarter and faster - augmenting developers rather than replacing them.
Modular functions: speed through composition
One of the most promising uses of AI in coding is the generation of small, modular functions. These bite-sized blocks of logic can be reviewed, tested, and assembled into larger systems. Rather than building the entire solution, AI provides developers with high-quality building blocks, like well-shaped bricks, that speed up construction but still require human hands to create the full structure.
This modular approach accelerates development without sacrificing control. It gives developers a flexible toolkit that reduces the overhead of writing boilerplate code while preserving architectural oversight.
When AI is used in this way - as a builder of well-defined, discrete components - it becomes easier to manage code quality and reduce the risk of introducing hard-to-trace bugs. The developer remains the architect, ensuring the final product meets performance, security and design requirements.
Debugging, testing and documentation
AI’s pattern recognition abilities make it a handy tool for debugging. It can identify syntax issues, propose optimisations and even highlight logic flaws that might be overlooked. It helps trace runtime problems and can offer context-specific fixes that speed up resolution.
AI can also automate test generation. By analysing code paths and predicting inputs, it improves test coverage and helps catch issues earlier in development. This improves reliability and reduces the burden of manual testing.
Documentation is another area AI can assist. It can explain code behaviour, summarise changes, and improve project visibility. This supports maintainability, collaboration and onboarding.
These forms of automation allow developers to focus on design and architecture while helping teams move faster without compromising quality.
Challenges: control, clarity and accountability
Despite its strengths, integrating AI into coding workflows brings important challenges. One of the biggest is explainability. Developers must still understand the code, how it works, why it was written that way and how to adapt it in the future. Relying on AI for complex logic can lead to code that is harder to maintain or audit.
AI may also miss edge cases. While it handles standard code well, it may not anticipate unusual inputs or subtle conditions that a human would catch. Without careful review, these gaps can result in hard-to-detect bugs or security vulnerabilities.
Another concern is design ownership. Letting AI make decisions about how features are implemented can lead to inconsistency and architectural drift. Developers need to stay in control of design direction and uphold coding standards to ensure long-term quality and cohesion.
How can developers prepare for the AI Age?
To make the most of AI, developers must go beyond simply knowing how to use tools. They need to assess AI-generated code critically, understand its implications, and know when human input is essential. Recognising the limits of AI is just as important as knowing how to apply it effectively.
Understanding the reasoning behind the code remains a core responsibility. Without that insight, developers risk inheriting systems they can’t explain, maintain, or evolve. Skills like refining AI-generated documentation, spotting missed edge cases and guiding design choices will continue to be essential.
The developers who succeed in an AI-assisted future won’t step away from the craft. They’ll stay close to the work - reviewing, shaping and maintaining code - to make sure software is not just delivered quickly, but is built to last.
