I built interactive playgrounds where AI helps...

How it all started A few years ago, I created RustInsight. It was a set of step-by-step Rust courses where the reader built an application by following instructions — kind of like assembling a LEGO set. You’d go step by step, adding code to source files, and that’s how you learned Rust. At the same time, the application was being built as you progressed, so you could always see what the final result should look like and compare it with your own work. In the end, you didn’t just learn — you pract
