Expected result
Here is a file with the extra line breaks manually removed.
Here’s a **clear, technical, no-nonsense comparison of Rust vs Go**, tailored for someone who works with infrastructure, backend systems, and performance-sensitive tools like you do.

# 🔥 **Rust vs Go: A Practical Comparison**
Both languages target system-level and backend development, but they are optimized for _very_ different design goals. Here’s how they compare across the dimensions that actually matter in real-world engineering.
---
## 🧠 **Philosophy**
### **Rust**
- Zero-cost abstractions, maximum control.
- Guarantees memory safety _at compile time_.
- Focuses on correctness, performance, and low-level control.
- Prefers explicitness; avoids hidden behavior or magic.
### **Go**
- Simplicity and speed of development above all else.
- Garbage-collected, opinionated, minimalistic.
- Designed for large distributed systems and teams.
- Focuses on readability and maintainability.
---
# ⚙️ **Performance**
### **Rust**
- As fast as C/C++ in many workloads.
- Zero-cost abstractions, no GC pauses, fine-grained control.
- Better throughput for CPU-heavy tasks, async event loops, crypto, compilers, image processing, etc.
### **Go**
- Still fast, but GC can introduce latency (though much improved).
- More overhead in tight loops, high-CPU workloads, or where memory layout matters.
- Fantastic for IO-bound server workloads.
**Verdict:** Rust wins for raw performance and predictable latency; Go wins for most web servers.
---
# 🛑 **Memory Safety & Concurrency Model**
### **Rust**
- Borrow checker ensures no data races at compile time.
- Fearless concurrency: if it compiles, it’s safe.
- But learning the ownership/borrowing model can be _hard_.
### **Go**
- Simple concurrency model via goroutines + channels.
- GC removes memory-management burden.
- But data races are still possible; requires discipline + `-race` detector.
**Verdict:** Rust = safety; Go = simplicity.
---
# 🧵 **Async Model**
### **Rust**
- `async/await` is powerful but… complicated.
- Ecosystem fragmented (`tokio`, `async-std`, `smol`).
- Exceptional performance for async IO.
### **Go**
- Goroutines are lightweight threads with synchronous syntax.
- No async/await ceremony.
- Much easier to write and reason about.
**Verdict:** Go’s concurrency model is one of the best in all of programming.
---
# 📦 **Ecosystem & Tooling**
### **Rust**
- Cargo is arguably the best build system + package manager in any language.
- Excellent compiler messages.
- Strong library ecosystem for:
- systems programming
- cryptography
- WASM
- embedded
- Weaker for high-level web frameworks or enterprise-y stuff.
### **Go**
- Standard library is shockingly complete.
- Tools (formatter, linter, vet, benchmarks) built in.
- The ecosystem revolves around cloud/server workflows:
- HTTP servers
- microservices
- DevOps tooling
- CLIs
- Less pleasant for low-level binary manipulation, unsafe code, custom allocators, etc.
---
# ⏱️ **Developer Experience**
### **Rust**
Pros:
- Beautiful types
- Strong guarantees
- Compiler guides you
Cons:
- Steeper learning curve
- Compile times can be slow
- More code to write for simple tasks
### **Go**
Pros:
- Dead simple
- Very fast builds
- Easy to onboard new engineers
- “It just works”
Cons:
- Too simple for some (error handling boilerplate)
- Limited generics (improving)
- Fewer safety guarantees
---
# 🧰 **Use Cases**
### **Rust is best for:**
- High-performance servers
- Network proxies, load balancers (e.g., Linkerd, Fly.io, vector.dev)
- Cryptography
- Embedded systems
- CLI tools needing speed + safety
- Replacing C/C++ libraries
- WASM
### **Go is best for:**
- Cloud native services (Kubernetes, Docker, Terraform, Vault)
- Backend APIs
- DevOps tooling
- Distributed systems
- Anything with high IO / concurrency
- Team projects with mixed skill levels
---
# 🥇 **Which Should YOU Use?**
Given your background (Python + infra + security + CLIs + backend tooling):
### **Choose Rust if:**
- You want max performance + safety.
- You’re building a performance-critical CLI or backend service.
- You’re replacing or interfacing with C/C++.
- You want deterministic latency for networking/security tools.
### **Choose Go if:**
- You want to ship quickly.
- You’re building distributed infra tooling or microservices.
- You need concurrency without pain.
- You want something maintainable by a broader engineering team.

If you want, I can also compare:
✔ Rust async vs Go goroutines
✔ Rust vs Go for CLI tools
✔ Rust vs Go for Kubernetes-friendly microservices
✔ Example code in both languages side-by-side
✔ Performance benchmarks for your specific workload
Just tell me what angle you want next.

Additional information
Note: I found the thread Copy-And-Pasting Headers From ChatGPT -> formatting mess - #12 by rigmarole in the Help category, but most of that thread doesn’t describe the issue well, although this post in the thread does a decent job, these were not bug reports.
Issues with extra line breaks in lists in from non-ChatGPT content was mentioned 4 years ago, but again, not as a bug: Fixed issue with "Pasting formatted text gives double line breaks between list items".
