AI was supposed to help juniors shine. why does it mostly make seniors stronger?

AI was expected to make junior developers more valuable, but instead is primarily benefiting seniors. While AI excels at generating boilerplate code and speeding up routine tasks, it struggles with architecture, security, and high-quality code design - areas where senior developers provide crucial oversight. This technology amplifies the effectiveness of experienced programmers who can properly direct and evaluate AI output, rather than democratizing coding as initially predicted.
