🔗 I'm sorry, but you still have to think.

DHH, the creator of Ruby on Rails, chose to rewrite Campfire Once from Ruby on Rails to Rust, relying on a developer to handle the Rust code due to his discomfort with it. This decision, along with rewrites in languages like Elixir and Go, offers insight into the challenges faced by those using AI agents for coding without understanding the code themselves. The results weren't promising; they highlighted the necessity of specificity in prompts, as many programming decisions come down to subjective choices. While Elixir's version stayed closer to the original Rails architecture, both rewrites exhibited significant trade-offs. Rust payments weak performance in certain aspects, including a low new post delivery rate under heavy load due to its limited broadcast channel capacity. The comparative analysis emphasizes that programming decisions are complex and a single metric doesn’t tell the whole story. Ultimately, it reinforces the importance of thoughtful coding practices and understanding the nuances of each programming language's features and limitations.
