AI can migrate your entire codebase. Reviewing it is another story

The text discusses the challenges of code migration and PR (Pull Request) reviews in the context of evolving AI tools, highlighting a shift from the burden of generating large diffs to the complexity of effectively reviewing them. It uses the example of the Bun project, which underwent a significant migration from Zig to Rust, facilitated by AI, to illustrate how such migrations are becoming more common. Despite AI's assistance in code generation, the review process remains challenging due to the sheer size of PRs and the difficulty in understanding changes across different programming languages. CodeRabbit aims to address these challenges by providing tools that emphasize context and intent in reviews, making it easier for developers to comprehend and discuss large-scale code changes. The text underscores the importance of understanding the intent behind code changes and improving the review process to adapt to the increasing size and complexity of PRs in both corporate and open-source environments.
