Is Rust really the Solution to Security?

Rust is mostly the solution to some common security problems.

It's not the total solution because you can still to unsafe things in Rust. You just have to try harder.

And it's not the solution to every security problem. Rust will (I suspect) let you read data from the net, save it to a file, and then call "curl | bash" on that file. That's not the kind of issue that Rust tries to prevent.
