You're right, this Hello World doesn't tell anything about the language, its syntax, semantics, what these have to do with safety. But you find this nonsense, as you say, everywhere.
But how to begin? The opinions vary. They depend on the audience - beginner, experienced,...

I say: Give them a simple problem and ask: What kind of (numeric) type do you need to fulfil the needs of the solution.
Others disagree: It's to complicate for a beginner to say "type Meter_Rod is range 0 .. 2_000;", just use Integer for the beginning.

The question is: How to avoid bad habits from other languages from the beginning?
