What AI changes about the work of developers: how many programmers are needed, PHP in 2027 and teams that no longer understand their own AI code.
AI writes a growing share of the code. This topic is about what that means for the work of developers, with figures and research instead of predictions.
More or fewer programmers needed in 2027? puts the figures from CBS, UWV, Eurostat, the American BLS and Indeed side by side, and shows why starters in particular have a hard time. PHP and AI in 2027 is about what the models can do now and what changes for PHP developers.
Code nobody on the team understands any more is called cognitive debt. The first article explains the idea; the 2026 follow-up shows what research says about it now and where it leaks in web applications. And What AI did to databases compares Oracle, SQL Server, MySQL, MariaDB, PostgreSQL and SQLite, measured in PHP, with a choice per kind of web application.
Almost every database gained a vector type, but MySQL Community cannot search with it. What AI changed in Oracle, SQL Server, MySQL, MariaDB, PostgreSQL and SQLite, measured in PHP, and which database to choose for which web application.
In 2026 cognitive debt gained a model, a place on the Thoughtworks Radar and a first experiment with a web application. What the research says now, where it leaks in backend and frontend, and what a web team can do.
Will we need more or fewer programmers in 2027? What CBS, UWV, Eurostat, the US BLS and Indeed show, what AI really delivers in controlled studies, and why beginners have it hardest.
Where do AI models stand in October 2026, and what does 2027 bring for PHP developers? On PHP2Shell, the flaw AI found after twelve years, prices and benchmarks, PHP 8.6, versions running out, the Cyber Resilience Act and a working day in 2027.
Cognitive debt is the gap between how your system works and how well your team understands it. What research says about it, and how to prevent it without ditching AI.
