UK employers may need to rethink how they approach technical skills development as new research suggests software professionals are rapidly shifting their learning focus from traditional programming topics towards artificial intelligence.
Analysis by learning platform O’Reilly found that usage of Generative AI content among UK learners increased by 89% between the first quarter of 2025 and the same period in 2026. Overall learning in AI and Machine Learning rose by 51%, while Data-related content now accounts for almost one-third (31%) of all UK platform usage, making it the largest subject area.
The findings suggest experienced developers are increasingly relying on AI-powered coding assistants and integrated development tools to support day-to-day programming, allowing them to dedicate more formal learning time to emerging AI technologies.
Over the same period, engagement with Programming Fundamentals fell by 73%, while Agile and Git training declined by 31% and 20% respectively. However, O’Reilly argues this reflects changing learning behaviours rather than diminishing technical capability.
The findings underline the importance of evolving workforce development strategies to balance AI skills with strong technical foundations.
Despite the rise of AI, employers continue to value established software engineering skills. Technologies including React, Node.js and Java remain among the UK’s most sought-after skills in technology recruitment, while cloud certifications continue to be highly regarded by employers.
The research also found continued demand for software engineering best practice, with learning around Clean Code increasing by 19% and C# growing by 17% year-on-year.
Alexia Pedersen, SVP International at O’Reilly, said the data reflects a workforce making deliberate decisions about where to invest its learning time.
She said many experienced developers are using their existing programming expertise as a foundation for adopting AI tools, but warned that AI should complement, not replace, core software engineering knowledge.
The report highlights the growing need to tailor learning and development programmes differently for experienced professionals and early-career employees. While established developers may be well placed to accelerate AI adoption, newer entrants to the workforce still need opportunities to build the programming knowledge and technical judgement that underpin long-term career development.
