Every Rust talk/paper currently starts with "Rust is a systems programming language offering memory safety and performance ...", surely at some point we have to start assuming the audience know about Rust like Java and Python?

Whenever I watch a talk on Rust (except in a Rust-specific conference), I have to skip the first minute or so because the all the speakers just repeat the same basic description about Rust. Some even go on much longer and try to introduce Rust's ownership and borrowing system from scratch. But in a Java talk, no one starts with "Java is an object oriented language running on a cross-platform VM blah blah blah", and they don't try to explain how garbage collection works (unless that's relevant to the talk, of course), they just go straight into the topic. The same goes for academic papers.

If the audience are Rust learners or CS freshers, then it's fair to start from the basics. But most talks target people who have been doing CS professionally or academically for years. I understand that this was necessary when Rust was "novel" and "experimental", but haven't we passed that mark already? If not, then when can we start assuming a professional CS audience all at least know what Rust is about?
