Rust has exploded in popularity in recent years. At the same time, fewer and fewer people are actually _writing_ code — more and more are orchestrating it through AI agents.

Which brings us to an interesting paradox.

**Thesis 1: AI favors Rust.** Rust’s borrow checker is a nightmare for the human brain — a cognitive tax that pushes programmers toward simpler languages. But an AI agent doesn’t get tired. It doesn’t care if it has to fix the same lifetime error five times in a row. If a machine doesn’t feel frustration, then Rust’s biggest flaw for humans stops being a flaw for AI. Rust could become the _default_ language of agentic coding — safety without the human cost.

**Thesis 2: But if agents get close to error-free, C makes a comeback.** The entire point of Rust is to prevent mistakes humans make out of carelessness — dangling pointers, race conditions, buffer overflows. If an AI agent practically stops making those mistakes, why keep paying Rust’s complexity tax? C is minimal, predictable, close to the metal — and arguably easier for a model to reason about too, since it doesn’t carry fifteen layers of ownership syntax. The safety net becomes redundant once the tightrope walker never falls.

**Thesis 3: Maybe both are just a transitional phase.** If programming eventually shifts almost entirely to agents, why would we keep languages designed for human readability, human mistakes, and human ergonomics at all? Sooner or later a language could emerge that’s deliberately built for machines — not optimized for “human-friendly” syntax, but for what models are actually good at: precision, information density, formal verification. A language no human would want to hand-write — or need to.

* * *

Question for you: where does this land? Does Rust become the agentic standard because it removes human frustration as an obstacle? Does C reclaim the throne because AI stops making the classic mistakes anyway? Or in a few years are we looking at a third language that no human designed for themselves?

let f=|n:i32|->i32{let mut a=0;let mut b=1;let mut c=n;while c>0{let t=a+b;a=b;b=t;c=c-1;};return a;};
println!("{}",zzz);let mut result:Vec=Vec::new();for i in 0..5{result.push(f(i))
;};if result.len()>0{println!("{:?}",result);}else{println!("empty")};
match x.len(){0=>println!("nothing here"),=>{let s:i32=x.iter().sum();
