AI like ChatGPT, recall what it actually does and doesn't do. It doesn't know things. It doesn't learn, or understand, or reason about things. What it does is probabilistically generate text in response to a prompt. That can work well enough if the context you need to describe the goal is so simple that you can write it down and include it with the prompt. But that's a very small class of essentially trivial problems. What's worse is there's no clear boundary between software development problems that are trivial enough for an LLM to be helpful vs being unhelpful. The LLM doesn't know the difference, either. In fact, the LLM doesn't know the difference between being tasked to write javascript or a haiku, beyond the different parameters each prompt would activate. And it will readily do a bad job of responding to either prompt, with no notion that there even is such a thing as a good or bad response … The hard part of programming is building and maintaining a useful mental model of a complex system. The easy part is writing code. They're positioning this tool as a universal solution, but it's only capable of doing the easy part. And even then, it's not able to do that part reliably. Human engineers will still have to evaluate and review the code that an AI writes. But they'll now have to do it without the benefit of having anyone who understands it. No one can explain it. No one can explain what they were thinking when they wrote it. No one can explain what they expect it to do. Every choice made in writing software is a choice not to do things in a different way. And there will be no one who can explain why they made this choice, and not those others. … But it's worse than AI being merely inadequate for software development. Developing that mental model requires learning about the system. We do that by exploring it. We have to interact with it. We manipulate and change the system, then observe how it responds. We do that by performing the easy, simple programing tasks. Delegating that learning work to machines is the tech equivalent of eating our seed corn. That holds true beyond the scope of any team, or project, or even company. Building those mental models is itself a skill that has to be learned. We do that by doing it, there's not another way. As people, and as a profession, we need the early career jobs so that we can learn how to do the later career ones. Giving those learning opportunities to computers instead of people is profoundly myopic.
