You are wrong here, mate. If borrow checker prevents mass adoption, I am okay with that. I have dabbled enough problems in poorly written code by "full stack" developers who write code by combining different blog-posts from Medium without any thoughts to underlying memory model, that I am happy that some language feature prevents these folks to take up a Language.
You might not care if Rust fades into obscurity, but many do.
