为什么值得看
Rust 书籍作者发文指出，除非团队已有 Rust 专家，否则不建议跟风 Amazon、Cloudflare 等大厂迁移至 Rust。核心矛盾在于学习曲线陡峭与业务交付压力之间的错配。

这篇文章的争议性恰恰在于作者身份——他靠教 Rust 赚钱却劝退新手，说明问题足够真实。大厂迁 Rust 的隐藏前提是：有专人做基础设施抽象、有预算养编译时间、有权限拒绝业务 deadline。
中小团队真正该算的不是 Rust 多快，而是'第一个生产 bug 出现时团队能不能在 2 小时内定位'。如果答案是否定的，Go 或甚至 Python + Rust 扩展的混合架构才是更务实的路径。
另一个被忽略的点是：Cloudflare 们迁 Rust 往往是从 C/C++ 迁，不是从 Python/Go 迁。你的起点不同，成本收益完全不同。

核心争论：Rust 是否适合无专家团队的业务后端开发，学习成本与收益是否匹配
Lots of tortured logic in this post. 1. You shouldn't pick a programming language the team doesn't know. That's common sense, not an argument against Rust. 2. Rust ranks lower on the most used languages list because it's newer than Java, Python, C, and all of the others higher on the list. 3. You do
For the use cases the author is alluding to, you do need to use async. Non-cooperative threaded multitasking isn't a real choice for backends, and Rust doesn't have virtual threads. Before Java got virtual threads in Project Loom, people were typically using some promises equivalent even though it m
> why Rust and Python put so much effort into adding event loops after the fact. Perhaps Python, but Rust went the other way - it had all that stuff built and it was removed.
