 # Quote of the Week
 
-> Python and Go pick up your trash for you. C lets you litter everywhere, but throws a fit when it steps on your banana peel. Rust slaps you and demands that you clean up after yourself.
 
-– [Nicholas Hahn on his blog](http://www.nicolas-hahn.com/python/go/rust/programming/2019/07/01/program-in-python-go-rust/)
 
-Thanks to [UtherII](https://users.rust-lang.org/t/twir-quote-of-the-week/328/662) for the suggestion!
+> > Are we trying to steal the JVM’s “compile once run everywhere” concept?
+
+> No, we just borrow it mutably.
