The vast majority of anti-Rust people are stubborn and toxic types who don’t know it and refuse to learn. On the other end you have those who do use it, know why it’s such a good language, and criticize it constructively so that it continues to improve. Rust lacks many quality of life features that other languages have, but that is by design. It’s meant to create rock-solid software and forces you to think about things like lifetimes and ownership scopes that other languages let you take for granted.

You can’t easily move from languages like C++ or Python to Rust without learning and accepting new concepts and patterns. If someone can’t or won’t do that, they should not be doing any programming.
