Local Reasoning for Global Properties

The author believes that programming languages can help prevent bugs in AI-generated code by enforcing global properties, such as data race freedom, through local reasoning. The author uses Rust as an example of a language that enforces data race freedom through ownership types and traits, and suggests that this approach could be applied to other languages to improve code reliability and productivity.
