Convincing your manager to let you try Rust

Rust is motivated by an overarching idea: developer happiness and low-level control aren't mutually exclusive. But many developers aren't in an environment where they can easily try experiments with new languages. Wouldn't it be nice if languages like Rust came with a business case?

In this talk, John will show you how Rust gives you superpowers, while also tying them to valuable outcomes your manager will care about. By the end of the talk, you should feel empowered to try it out yourself with your team!


Rust: try it!


  • Equip folks with an understanding of the core ideas and syntax of Rust
  • Show them how to get started and write simple Rust programs
  • Connect the value propositions of Rust with business outcomes that managers care about


Developers and team leads who want to expand their horizons.
