I’ll let others chime in here as well, but some thoughts:
- Rust is a systems engineering language; while it’s very powerful some of its capabilities may not be very useful for developing IC apps
- Rust is about 10 years old at this point so documentation and libraries are more mature than Motoko
- Motoko is purpose built for the Internet Computer; as such it will always feel “native” to IC development
- Both programming languages are strongly typed, statically compiled languages
- Motoko is designed to be readable and familiar to JavaScript
If you already know Rust, then going with Rust makes sense. If you are a JavaScript developer, Motoko might be an easier path. You can find Motoko examples in our dfinity/examples repository.
If you are an expert in an alternative language whose Wasm compatibility is stable for production usage and are interested in a challenge, we are actively looking for teams wanting to implement canister development kits.
