• The rewrite was completed in just 6 days, showcasing the potential of AI-assisted development.

The Internet’s Verdict: 70% Hyped, 30% Skeptical

The Reaction

Some developers are excited about the potential benefits of the Rust rewrite, while others are skeptical about the use of AI in the development process.

Developer Insights

One developer who works on Bun notes that the rewrite is still experimental and may not be committed to the main project.

I work on Bun and this is my branch. This whole thread is an overreaction. 302 comments about code that does not work. We haven’t committed to rewriting. There’s a very high chance all this code gets thrown out completely.

Another developer expresses concerns about the project’s direction and the potential consequences of using AI-generated code.

Completely unbased, but I don’t want to have to do anything with bun anymore. It’s just a gut feeling, but I don’t trust them and support them.

However, some developers are optimistic about the potential of Rust and AI-assisted development.

Rust is perfect for writing all of code using LLM. It’s strict type system makes is less likely to make very dumb mistakes that other languages might allow.
