I've been away from the corporate software industry for a while and currently use AI tools through their free or limited plans. One tool handles basic frontend work surprisingly well, but needed much more guidance when I asked it to build a Flutter app. Another coding agent is so slow and quota-limited that it is difficult to use consistently.
I keep seeing two very different claims: some developers say tools such as Claude Code let them work so quickly that they barely write code anymore, while others say AI still hallucinates, needs constant supervision, and produces code that requires extensive cleanup. Those statements sound contradictory, so I'm looking for a realistic picture of where AI actually helps software engineers today, what its limitations are, and which skills remain important.

AI’s value depends heavily on the person using it. Developers who understand architecture, debugging, testing, security, and the business problem can delegate more work safely. Someone who cannot evaluate the output may simply produce more code and more defects. It is also worth remembering that many people use AI only for autocomplete or repetitive tasks, while others use it to generate whole features, so reports about productivity are not directly comparable. The profession is changing, but software fundamentals and the ability to reason about systems are still essential.
Those views can both be true. AI can complete a large amount of routine work, but it does not reliably understand the product direction, hidden constraints, or consequences of an architectural decision. It is a bit like an aircraft’s autopilot: it handles many normal operations, but an experienced pilot still needs to set the course and take over when conditions become unusual. The more complex or unfamiliar the task, the more important it is that someone can inspect and correct the result.
AI is usually strongest on well-defined tasks in a codebase with clear requirements, familiar patterns, tests, and linting. It can produce a useful first pass, refactor repetitive code, generate scripts, and handle transformations across many files. It behaves much more like a very productive junior developer than an autonomous senior engineer: generally capable, but prone to rough code, odd design choices, missed edge cases, and security mistakes. Experienced developers often get more value from it because they know how to specify the work and review the output.
The biggest danger is letting AI-generated requirements and AI-generated code feed into each other. If the requirements are vague and the project is already mostly machine-written, the tool can create increasingly complicated code that appears to work but is difficult to maintain. Human-written specifications, clear boundaries, conventional libraries, and incremental changes help prevent that. AI is useful as an implementation assistant, but it should not be the only source of design decisions.
A productive workflow is to use a stronger model for planning and clarification, then use a cheaper or faster model to implement the approved plan. Spend time defining acceptance criteria, interfaces, edge cases, and what must not change. Afterward, run unit, integration, and end-to-end tests along with linters, security scans, and architecture checks. These guardrails turn AI output into something more dependable instead of trusting it because the code looks plausible.
That matches my experience too. I use AI for throwaway utilities without caring much about the generated code, but production changes still need careful review and a second human review. Good tests and static checks make repetitive changes much safer.
