It was poorly justified up-front but frankly I did not need the examples to understand Jarred’s frustration.

What I found helpful were his explanation of how the interaction with JavaScript’s garbage collector created unique challenges for Bun. Andrew did not address this point at all. It was also helpful to understand how the test suite covered the new code - many people had assumed the tests were also vibe translated and couldn’t be trusted. Andrew pretends he didn’t understand that tests don’t catch all bugs, which is true of all software including Zig.

To me this whole exchange is mostly the typical “memory unsafe languages lead to time consuming and disruptive defects that can be almost entirely prevented with a choice of programming languages” versus the “git gud and don’t write bugs” response.

Layer on the AI tension, Anthropic’s involvement and Andrew’s classic Linus impersonation and of course its viral.
