Episode notes
AI Excels At Human Signals
- AI shines at extracting human signals (comments, names) that static analysis cannot prove.
- Use those signals to guide transformations but rely on AST-based codegen for correctness.
Cedar Rust Converter Exists Today
- Matt describes translating C/C++ to idiomatic Rust and stresses most code can be lifted into safe Rust.
- Cedar (Rust converter) is product-stage but still early and available to try on Compiler Explorer.
High-Correctness AI Is Underexplored
- Many AI efforts focus on IDE autocomplete while the bigger opportunity is high-correctness code migrations.
- Matt argues for AI that augments analyses to reach 99.9% correctness for automated changes.
