This is plain wrong, and it undermines the credibility of the author and the rest of the piece. Rust did not invent ownership in the abstract; it relies on plain RAII, a model that predates Rust by decades and was popularized by C++. What Rust adds is a compile-time borrow checker that enforces ownership and lifetime rules statically, not a fundamentally new memory-management paradigm.
However, I also don't understand how people don't see the usefulness of what Rust put to the mainstream: algebraic data types, sum types, traits, etc.
I also get super annoyed when people think Rust is only chosen for "safety". Says frustrating things like "so I can just use unsafe", because no you don't and if you do I would reject your changes immediately.
Honestly, in general, I am just annoyed when people don't use the right tool for the right job. And attempts to fix the tool with more bespoke stuff on top it.
This is the kind of hostility (which is frankly toxic) that’s become associated with parts of the Rust community, and has fairly or not, driven away many talented people over time.
