Writing code is the equivalent of swinging a hammer. A more experienced engineer might swing it better than a junior, but swinging hammers isn't what makes an engineer valuable.

These AI models don't actually understand anything about what they're generating, not to mention the world they're supposed to building solutions for. They're just using statistics to predict the next likely output based on some input. Maybe there is a way to incorporate these things into the development process today, but I think we're still far away from seeing an AI replacing a human engineer.
