Rust never sleeps — it argues
The limits of Rust, or why you should probably not follow Amazon and Cloudflare
Even Rust fans are fighting over whether copying Big Tech is a costly trap
TLDR: The article argues that Rust, a popular newer programming language, is often a bad fit for ordinary teams despite the hype from giant companies. Commenters split fast: some called the warning obvious or overblown, while others agreed that following Big Tech trends can turn into expensive busywork.
A Rust expert just lobbed a spicy warning into the software world: don’t copy Amazon or Cloudflare just because they’re obsessed with Rust. His case was simple but brutal: the language can be great for some high-stakes jobs, but for many normal teams it can become a time sink full of rewrites, update churn, and library chaos. In plain English, he’s saying the shiny “safe and modern” language may not be worth the pain unless your team already lives and breathes it.
And the comments? Instant food fight. One camp basically yelled, “This is just common sense dressed up as anti-Rust drama.” Aurornis argued that “don’t pick a language your team doesn’t know” isn’t some grand revelation, while others rolled their eyes at what they saw as exaggerated doomposting about updates and complexity. cbsmith went full meme mode, calling it “a bizarre article,” while irishcoffee delivered the most exhausted take of the thread: Rust is a tool, not a religion, and people need to stop acting like choosing a coding language is a moral crisis.
But the post also found backup. Some readers said the author’s real point was refreshingly practical: for small and medium projects, especially ones needing lots of internet-related juggling, Rust can be more hassle than hero. The funniest running joke was that Rust is starting to sound like the metaverse of coding: everybody talks about it, admires it, and then quietly uses something else at work
Key Points
- •The article argues that Rust is usually not the best default choice for a project unless the team already has substantial Rust expertise.
- •The author says large-company adoption of Rust by firms such as Amazon, Cloudflare, Google, Meta, and Discord should not be treated as a universal model for other teams.
- •The article identifies async programming in Rust as a major source of complexity, including event-loop blocking, ownership difficulties, and incompatible runtimes and libraries.
- •The author states that Rust’s frequent releases and editions create maintenance overhead for toolchains, dependencies, and older projects that need updating later.
- •The article argues that Rust’s standard library is too limited and that developers need a stronger library ecosystem to solve business problems efficiently.
