A young engineer may attempt what nobody has ever done, but if somebody has already done it they are obliged to call that person and hear their advice.

It is totally okay for a young engineer to do something they've never done before just the way it's okay for them to do something that nobody has ever done before. But uh but if somebody has done it before in the world, uh our rule is you have to go find one of those people, call them, and ask them your advice. And you don't have to take it. You just have to hear it.
