It's not marketing. They created a solution to a problem no one 
else has been able to. Trying the language, and it solving your 
problems and then continuing to use the language afterwards isn't 
marketing. It is a completely refined package all the way down to 
it's package manager.

It's not just memory safety. Have you used Rust? How you written 
Rust? Have you had to deal with a new version of Rust that breaks 
all your code? Have you used cargo? Have you used a cargo package 
that uses a different version of Rust that you use and it just 
works TM?

Rust is memory safe, but to attribute its success entirely on 
that is moronic. A GC is memory safe, do you think Rust would 
have been as successful with a GC? Rust provides more guarantees 
than simply being memory safe. Something a GC doesn't provide.
