Reasons not to use Rust

- You think programming languages should be closed and proprietary
- You like random pauses caused by forced collection of the garbage
- You think program start-up should take minutes so you use stupid VM-languages instead
- You like broken features and memory corruption
- You sell hardware and want to deploy inefficient scripting languages only to sell more
- You only do pure programs that don't interact with the world
- You are a retard who doesn't understand the concept of ownership

Anything else?

The Rust implementation is open source. Because of this it is absolutely possible to know what a piece of code does without relying on human interpretation.

No one has ever produced a widely useful language in the way you are proposing.
