>Software engineers are able to step back, think about the whole thing, and determine the root cause of a problem.

Agree strongly, and I think this is basically what the article is saying as well about keeping a mental model of requirements/code behavior. We kind of already knew this was the hard part. How many times have you heard that once you get past junior level, the hard part is not writing the code? And that It's knowing what code to write? This realization is practically a right of passage.

Which kind of begs the question for what the software engineering job looks like in the future. It definitely depends on how good the AI is. In the most simplistic case, AI can do all the coding right now and all you need is a task issue. And frankly probably a user written (or at least reviewed, but probably written) test. You could make the issue and test upfront and farm out the PR to an agent and manually approve when you see it passed the test case you wrote.

In that case you are basically PM and QA. You are not even forming the prompt, just detailing the requirements.

But as the tech improves can all tasks fit into that model? Not design/architecture tasks - or at least without a new task completion model than described above. The window will probably grow, but its hard to imagine that it will handle all pure coding tasks. Even for large tasks that theorhetically can fit into that model, you are going to have to do a lot of thinking and testing and prototyping to figure out the requirements and test cases. In theory you could apply the same task/test process but that seems like it would be too much structure and indirection to actually be helpful compared to knowing how to code.

What if LLMs get 'a mental model of requirements/code behavior'? LLMs may have experts in it, each with its own specialty. You can even combine several LLMs, each doing its own thing: one creates architecture, another writes documentation, a third critiques, a fourth writes code, a fifth creates and updates the "mental model," etc.

I agree with the PM role, but with such low requirements that anyone can do it.
