Why hasn't AI improved design quality the way it improved dev speed?

Upon reviewing the topic, it's clear that the disparity between AI's impact on development speed and design quality stems from fundamental differences in the nature of these two disciplines. Development Speed: AI has significantly enhanced development speed primarily due to its ability to automate repetitive, well-defined tasks such as: Code completion : AI-powered tools can predict and complete code snippets, reducing the time spent on manual coding. Bug detection : AI-driven testing frameworks
