Good question and since you asked so nicely, here is an answer:
Based on the search results, AI is significantly contributing to the amount of code being written in 2025. According to Elite Brains, AI now generates 41% of all code, with 256 billion lines written in 2024 alone. This indicates a substantial shift in the software development landscape, where AI is playing a major role in both generating code and assisting human developers.
The adoption of AI coding tools has been rapid, with 84% of developers using or planning to use AI coding tools in their workflow, as reported by Stack Overflow's 2025 Developer Survey. This widespread adoption suggests that AI is becoming an integral part of the development process, enhancing productivity and efficiency.
However, there are still concerns about the quality and reliability of AI-generated code. Developers are increasingly using AI tools but are also expressing less trust in them, which highlights the need for human oversight and review. This trend is reflected in the findings that developers are not satisfied with code that merely compiles; they want intelligent, context-aware suggestions that adhere to conventions and are backed by tests.
Despite the advancements, human coders still hold an edge in certain areas, particularly in competitive coding. For instance, at the 2025 AtCoder World Tour Finals, a human coder narrowly defeated an AI model, showcasing that human intuition and adaptability remain valuable in complex, high-pressure scenarios.
Overall, while AI is generating a significant portion of code, human developers continue to play a crucial role in ensuring the quality, safety, and maintainability of the final product. The future of coding appears to be a collaborative effort between AI and human developers, each leveraging their unique strengths to drive innovation and efficiency in software development.
