The amount of Rust code using unsafe is a major issues for a language build around safety. And yes, the same argument can also be made about Go having a unsafe keyword.

The fact that there exist crates to detected the usage of unsafe in dependencies, shows that its a rather liberal used keyword. Geiger comes to mind.

Unsafe in a language like Go is very rare, mostly because people do not program at such low system level to get the max performance out of it.

Rust code with unsafe: 1.7M Go code with unsafe: 400k

and for comparison, Go has about 2.3x the amount of repo's. So Rust has about a 10x more usage of the unsafe keyword.
