 # Quote of the Week
 
-<!-- QOTW goes here -->
+> At Cloudflare we have big Rust projects/teams and onboard new developers regularly.
+>
+> There is a learning curve. Rust is rigid and unforgiving, and noobs need assistance when the compiler says “no” (although error messages and Clippy do a good job for common mistakes).
+>
+> However, the big upside is that noobs can contribute safely to Rust projects. Rust limits severity of the damage an inexperienced programmer can cause. Once they manage to get the code to compile, it already has lots of correctness guarantees. “Bad” Rust code may just clone more than strictly necessary, or write 10 lines of code for something that has a helper method in the stdlib, but it won’t corrupt memory or blindly run the happy path without checking for errors. Rust prefers to be locally explicit, so it’s also easy to review.
