There is a good chance that your vibe coded C program segfaults immediately upon running and contains lots of subtle logic errors, all of which requires many iterations (finding issues at runtime) before you program runs as expected.

With Rust, you'll likely get many compilation errors, but if your syntax is correct, compilation errors will be few, and your code will almost certainly just work.

In order to use C you need to actually understand it, also toolchain is more complex etc. Which makes it a no go for 99%.

Rust is so safe that anyone can vibe it without any idea what is going on there. Which is basically what is happening here.

And why rust is more used than go for vibecoding? Mostly because of hype and performance gains which 99.9% of projects do not need.
