Have you even used Rust? Based on your other comments, it just seems like you have an axe to grind against anyone who uses Rust, coming up with accusations of "Rust devs trying to take 'er jerbs"
I like Rust fine. But Rust is not suitable for my work, where C++ is.
So, anyone saying "no programs should be written in C++" is saying, exactly, that I should not be able to do my work, and that I should not have employment.
That my current employer will not necessarily obey such an instruction does not make the attempt any the less offensive.
It's finally clear - You don't actually think that people are advocating for you to be fired[1]. You are just taking an absurd extreme position because after a career of not having to think too much about other languages something comes along that can actually threaten the C++ crown. Now you are worried that you'll be relegated to the niches along with your language, like assembler and cobol. Don't worry - there'll be room for you there even as C++ fades away: you can stay in the niches, or you can maintain the mountains of existing C++ code, or you can evolve and move forward with the rest of us.
You are a great case study in why the rest of us shouldn't comingle our identities with the identities of our tools.
[1] I did note that you changed it from "no new projects" to "no programs" a dirty trick that I'm only going to address by pointing it out.
Try to explain the difference between "no new projects" and "no programs". Any program I have not written yet would be a new project. Any old project is one where the program has already been written.
So you are being dishonest in pretending to a distinction without a difference.
Switching from the legitimate "you should use my new language because it is good" to "you should demote everybody coding <otherlang> to legacy maintenance, and put us in their place" admits a very ugly fact about yourselves and about your beliefs about your language's legitimate prospects.
If you believed it deserves a place on its own merits, you would not be trying to tear down other languages to try to make a hole for it. It is disgraceful behavior.
You should be ashamed of that, and you should be more ashamed of calling people who object "delusional".
> Any program I have not written yet would be a new project. Any old project is one where the program has already been written.
That is simply not any definition I've ever heard for a new project. You are assuming a binary of written or not written, and yet there are codebases that are incompletely written. That is what the parent means about ongoing projects that wouldn't migrate to Rust where you'd still be able to work on them, and who knows, maybe Rust won't overtake C++ and it'll continue, like many C projects have.
But that you have made yourself a "C++ developer," and not a developer in general who solves problems with whatever tool is best, does mean that whenever something comes along that threatens your identity, you seem to take it to absurdity, as the parent says.
