I shipped my first Rust kernel module last month. Zero panics in 14 months of production. But getting there? That was a nightmare. The initial setup took three days.

Different language, same plot. Five years ago, it was Go that would save us. Three years ago, it was microservices. Now it’s Rust. 500px Here’s what I’ve learned from watching rewrites: the lan...")

(Created page with "500px Have you ever imagined how a Rust async function resumes from the middle when an async I/O is complete? It feels like pure magic what rust does under the hood, for example: <pre> async fn get_user(id: i32) -> Result<User, Error> { let url = format!("https://api.example.com/users/{}", id); // wait until the api call completes let response = reqwest::get(url).await?; // then wait till the json stream to User struct,...")

But here’s the truth teams won’t admit publicly: the language is collapsing under its own complexity, and Go is quietly winning the only battle that matters — production velocity at scale. 500px The Hype vs. What Actually Ships Rust was marketed as the cure for memory bugs and systems-level fragility.

A transfer path slipped past a validator and moved money when it shouldn’t.
The rule existed in comments.
It didn’t exist in the shape of the code.
We reshaped the code around types.

The first time I saw a RefCell in Rust, I closed the tab. It felt like a betrayal. 
Rust was supposed to be safe, predictable, immutable by default. And now this thing — this box of interior mutability — was promising to mutate data behind an immutable reference. My brain screamed: “Isn’t that literally what Rust was built to prevent?” But then… it clicked.
