It does really help, in modern languages where they provide tools in the box and the ecosystem just accepts those as the default† tools, to have the default be that when you make a new project it just works, often by having it print "Hello, World!" or something else simple but definitive as proof we made a program.

† Default means just that, neither Rust's own compiler nor the Linux kernel need the cargo tooling, but these projects both have actual toolsmiths to maintain their build infrastructure and your toy program does not. There should be a default which Just Works at this small scale.
