Ask HN: Do you know of any company that went back to hand-written code?

A Hacker News user asks whether any companies have abandoned LLM-assisted code generation and returned to purely hand-written code, noting that some organizations have already scaled back their AI usage policies. Responses suggest this is unlikely to happen broadly, with commenters arguing that AI productivity gains are too valuable to abandon, though one startup founder mentions considering a partial revert to human-only code for their core functionality due to difficulties managing code quality and developer discipline when using AI tools.
