"Hey, you might be able to use Rust trivially if you stick to XYZ, but if you dare touch systems programming you're in for some real hurt. Dragons everywhere."
Why say that? It's not even remotely true - it's a gradient of learning. You can use Rust for simple problems as a gateway into systems programming.
Rust is honestly a great alternative to Python or Golang for writing servers. Especially given that you can deploy static binaries or WASM.
We need more people learning the language, not to scare them away.
Rust is getting easier year over year, too! People can choose Rust for their problems today and not struggle.
Give them a cookie and let them see for themselves.
