My Thoughts on the Bun Rust Rewrite

4 hours ago

Jarred initially had 'beginner energy' which was healthy for learning but led to mediocre engineering outcomes.
After Bun took venture capital and became a startup, Jarred's management style caused issues: poor communication, unrealistic expectations, and low empathy.
The Zig team found Bun's codebase problematic with hacks, abuse of assertions, and reckless feature development, leading to social distance.
The relationship between Zig and Bun deteriorated, culminating in relief when Bun was acquired by Anthropic and stopped donations.
The Rust rewrite announcement was welcomed by the Zig team to distance themselves from Bun's engineering practices.
The blog post about the rewrite is criticized for misrepresenting bug elimination, test suite effectiveness, and performance improvements.
Zig's compiler performance is highlighted as efficient compared to Bun's unmentioned compilation speed post-rewrite.
Despite criticisms, there is gratitude for Bun's donations to Zig and no personal ill will towards Jarred, but happiness that business interests are no longer intertwined.
