I'm not saying they don't exist, but they are a much smaller portion of the community than HN would have you believe.
You're telling me you don't see "why not rewrite it in Rust" posts in a forum dominated by people who are enthusiastically working on Rust codebases?
In the meantime, you did noticed that RiiR is already a meme, didn't you?
When one comes with this advocacy that safety === Rust in every discussion thread, this automatically shuts off the recipient of the message, which could otherwise be willing to actually listen to it.
'Rewrite it in Rust' is a mantra that makes a whole slew of assumptions that need to be validated before it can be considered a realistic option.
