Why I Chose Rust Over C and C++ for Drengr

Why I Chose Rust Over C and C++ for Drengr I'm the creator of Drengr , an MCP server that gives AI agents eyes and hands on mobile devices. I started this blog to share the engineering behind it. No pretending to be a neutral observer writing a think piece — I built this, and I'm here to talk about it. When I tell people I built a mobile automation tool in Rust, the first question is always "why not Python?" I've written about that in a separate post .
