When you have to prove your intelligence level (or rather "street cred") in a competitive market you have to show that you can learn the newest complicated things quickly. Rust is pure cryptonite in such a world.
It has been adopted by most large tech companies and several high profile open source projects within ~5 years of it's stable release. It certainly has been rapidly and widely accepted.
For important projects too: Google is using it in Android, Microsoft is using it in Windows, Amazon is using it for Lambda, Meta is using it for their source control tool, Dropbox is using for their storage backend AND in their client apps, Cloudflare is using it for their core proxy, etc.
