There comes a time in parents’ life when they need to accept the kid has grown up, and have to let the child interact freely with the world, while offering support.
There comes a time in project author’s life when they need to accept they can’t control every line of code (= develop), and have to let the project be developed by others, while overseeing it (= project lead).
The natural order of things.

The part about Rust is the ever-repeating echo of similar words about other programming environments across the years. My last language before I got retired was Java and in 2010 I’d say something along the same lines.
