“Wow, everything is broken lol.” That was the top comment on a GitHub issue about a Rust tool—ripgrep—crashing with a segfault during a large search. The internet laughed. But they weren’t just joking. They were accidentally telling the truth.
You’ve been sold a beautiful lie. That if you just use the right language, the right framework, the right set of safety guarantees, your software will be bulletproof. Rust promises memory safety without a garbage collector. It’s the golden child of modern systems programming. And yet, ripgrep—a Rust binary—segfaulted. Not because of a bug in Rust code. Because of a kernel bug. And a bug in musl libc. The layers beneath the language collapsed, and the safety guarantees evaporated.
The only truly safe system is a disconnected, unpowered pile of sand. Everything else is a house of cards.
Let’s be clear: this isn’t an indictment of Rust. Rust did exactly what it was supposed to do—it kept its own house clean. But the illusion of safety is that you can build a fortress on a foundation of marshmallows and call it secure. The ripgrep crash is a perfect, terrifying metaphor for modern computing: we stack abstraction upon abstraction, each layer promising invulnerability, but the reality is that every layer is held together by hope, duct tape, and decades-old C code running in the kernel.
The real story here isn’t the bug. It’s the philosophical wake-up call. Developers spend hours chasing segfaults in their own code, assuming they made a mistake. But often, the mistake is trusting that the ground beneath them is solid. It’s not. The kernel is a sprawling, untamed beast maintained by a handful of humans. libc is a legacy of compromises. The hardware has errata longer than a novel. And you’re supposed to write a safe app on top of that?
We need to stop pretending. Software reliability is not a property you can buy with the right language; it’s a continuous negotiation with entropy. Every segfault is a reminder that the universe is laughing at our attempts to impose order on chaos.
But here’s the twist: this is not a bug report. It’s a feature. The fact that such a crash is rare enough to be newsworthy is a miracle. The fact that we can build systems that work 99.999% of the time on top of this quicksand is a testament to human ingenuity. The problem isn’t the crash. The problem is our expectation that crashes shouldn’t happen.
Stop looking for the perfect tool. There is none. Every layer of abstraction is a promise until it’s broken. The only way to build resilient systems is to assume that every layer will break, and design for that. Graceful degradation. Defensive programming. Monitoring. And a healthy dose of existential dread.
So next time your tool segfaults, don’t curse the developer. Curse the universe. Then fix the layer you can control, and deploy a fallback for the layers you can’t. Because everything is broken—and that’s okay. It’s the only way anything ever works.
FAQ
Q: Does this single crash mean Rust is unsafe?
A: No. Rust's safety guarantees apply to the code you write in Rust. The crash was caused by bugs in the Linux kernel and musl libc—layers outside Rust's control. It's a reminder that no language can protect you from the entire stack.
Q: What should developers do differently after this?
A: Adopt a 'defense in depth' mindset. Assume every layer will fail. Use fault injection, monitor for unexpected crashes, and design fallbacks. Also, report bugs upstream—the kernel bug was fixed. The real lesson is to never trust any single layer implicitly.
Q: Isn't 'everything is broken' just a cynical excuse for sloppy engineering?
A: It's the opposite. Acknowledging the fundamental fragility of systems forces you to be more rigorous. The most reliable engineers are those who distrust their tools. The quote 'everything is broken' is a starting point, not a conclusion. It's a call to build with resilience, not resignation.
