That’s an interesting thought. It would run counter to everything we know about human nature, but interesting nevertheless.
Rust is already pretty successful adoption wise. It’s powering significant parts of the internet, it’s been introduced in 3 major operating systems (Windows, Linux, Android), many successful companies in a variety of domains have written their entire tech stack in it. Adoption as measured by crates.io downloads has doubled every year for the last 10 years.
Now I’m imagining how much more widely Rust would be used if they had adopted your visionary approach of never saying anything positive about it.
