Disagree. A lot of experience comes from a long career of changing projects and domains. You keep on encountering the same issues and problems in different contexts. I've been doing that for thirty years or so. Getting productive in new projects quickly is a good skill to have. It requires being efficient and mastering new things.

This is also the number one skill you will learn by getting a good education. Education can come in many forms. Some people never go to university for this and are self taught. It's easier than ever to teach yourself whatever you want to learn. In the end it's not about the stuff you learn but about learning to learn stuff. And having learned a lot of stuff, makes learning a new thing relatively straightforward. It's more of the same.
