I do know that Linus is on record with low opinion of C++. I have heard of him compare the cult-like following Rust has with the whole Vim/Emacs tribalism thing.
I've had discussions about my impression that Rust's build chain can be a bit surly compared to other popular languages.
I don't particularly mean it as a criticism - of course Rust's security enforcement comes with more warnings and errors.
But the novel part of the interactions, for me, was Rust community members coming at me with 'well get gud, newbie'.
These interactions are particularly ironic, given my experiences and specialties. I'm an old school veteran software developer. I have spent over half of my career in dedicated Cybersecurity roles.
These conversations converted me from a mildly interested Rust proponent into a casual Rust critic.
