> ...you don't know enough about Rust to see why they are promoting it.
If you have to know a lot about Rust to find out why you're using it in the first place, you certainly do have a chicken-or-the-egg problem. And, if the promotion doesn't leave you with a clear idea of why you might want to use Rust, that promotion couldn't have been very successful.
The same is true of any technology. One cannot give an informed opinion without first being informed about the technology in the first place. Technology moves forward because there are many whom are willing to leave the comfort of their boxes into the unknown to try things without being required to be convinced.
