Are companies moving away from AI-generated code and back to fully human-written code?

The wording makes this sound like companies went back to handwriting code, but compilers already made that obsolete decades ago. If you mean reverting from AI-assisted development to code written entirely by humans, then yes—many organizations are effectively still operating that way. AI is widespread in discussion, but not necessarily in production workflows.

Most companies never really switched away from human-written code. AI coding tools are usually optional or limited to things like autocomplete, chat assistance, or small experiments. Outside companies heavily focused on AI, the majority of production code is still written and reviewed by people.

There are definitely developers and companies that avoid AI-generated code, either because of quality concerns, security policies, licensing questions, or simply because the tools aren’t worth the extra review time. In many workplaces, human developers still do the core implementation while AI remains a minor convenience.

Some teams may experiment with agentic coding systems and then scale them back when the generated code takes too long to verify or maintain. That’s less a formal return to an old process and more a decision to use AI only where it provides a clear benefit.
