Research from McKinsey and GitHub shows that AI-assisted development can improve productivity by 20% to 55%, depending on the tasks. The advantage is so clear that for many companies, this has stopped feeling like a competitive edge and started feeling like table stakes. But something quieter is happening underneath that progress.​For years, junior engineers learned by doing unglamorous work. Writing simple implementations, debugging messy edge cases or poking around in code that didn't quite behave as expected. That's because those tasks helped engineers grow a feel for how systems actually work: from watching things break and figuring out why. There was no shortcut to it. They had to sit with the problem long enough to internalize it, and that process of internalization is what eventually became instinct.That kind of judgment doesn't arrive in bulk. It builds up slowly, through repetition. With AI now handling more and more of that early-stage work, a structural tension is emerging. Teams ship faster, but the surface where junior engineers develop critical thinking keeps shrinking.Speed Is Rising, Judgment Is NotThe International Journal for Multidisciplinary Research reported that junior developers experience greater productivity gains from AI tools than senior engineers. That difference sounds like good news until you look at what's driving it.Junior developers tend to accept AI sugg...
