AI code is cheap now, but the real cost starts later when you have to find out whether it can be trusted A few years ago, people in technology were valued for producing the first version fast. Today the first version is becoming cheap. A page of code, a summary, a plan, a reply, a draft solution can appear in seconds. That does not make people less important. It changes where their value lives. The real work is now in seeing what the machine did not understand, catching the quiet mistake inside a polished result, adding context, choosing what is safe, and carrying the responsibility when something affects real users, real money, or real decisions. The next strong person in IT may not be the one who writes the most from scratch. It may be the one who gives direction, sets limits, asks better questions, and turns fast machine output into something another human can truly rely on. AI is making production cheaper. That is exactly why judgment is becoming more valuable.
