Ruby for Good | Hacker News

A Hacker News post argues that method-level assertions make code easier for both humans and AI agents to write and maintain.

It also reports strong results using AI coding agents with Crystal, suggesting static typing can help agent-driven workflows.

Despite that, the post still recommends Ruby on Rails as the best choice for new full-stack applications.

Overall, it frames Ruby and Crystal as practical languages for AI-assisted development, especially where clarity and checks matter.
