I have spent my career as a C++ developer. What is more interesting to me about Rust isn't memory safety, but safe concurrency. But I have so much legacy code to deal with that all I can do is be influenced by Rust ideas: force all code to document assumptions about ownership and lifetimes, as if we had a borrow checker, and focus attention on redesign of code where this doesn't work cleanly.
