I've seen someone rewrite a wireguard proxy in rust for performance without realizing that it's just a daemon that interacts with the kernel to setup routing... But hey, at least the key generation is faster!
With the advent of A.I. these rewrites should be Full, but the generated code should only be used as a starting point. The code should be refactored so the engineers can take responsibility for maintaining and updating it.
But I'm afraid managers will force engineers to put the generated code straight into production unaltered so they can claim their million dollar bonuses. And when things go South they'll call on those same engineers to fix things yesterday.
Mostly the reasons are not of technical, but of political nature.
I mean no one likes to be told that their language is "not good enough". Or "not safe enough". It is our instinct to defend what we love and have put so much time and effort into. But reality is, that Rust really helps eliminate whole classes of errors, that can happen even to the most experienced C or C++ devs.
Accepting that things will and should be rewritten in Rust - until an even better language comes along - is necessary. That does not mean that Rust needs to replace all code on earth. For sure there are many cases where it should not. But in the times of Fable and GPT 5.6, it becomes even more important to reduce any attack surface as much as possible.

Step 3. Get internet points because an LLM Rewrote it in Rust!
2. Ignore any technical tradeoffs and considerations but solely lean on your guts and hypes on the Internet.
3. Ask Claude to rewrite the entire codebase to rust. Boom! Now you’re allowed to show off yourself on LinkedIn and HW as a super great rust engineer.
Honestly there should be a filter for these types of articles. I’m not going to bother reading something another person did not even bother writing.
memory usage dropped to half, execution speed is now 2x. Cross deployment is easy from silicon man to x64.
There are many low level optimizations available which i can exploit, compile is super fast for my project so development experience is better.
LOC dropped to half of the original.
Rust made life so much easier :)
