For me personally has been a good productivity tool. Mostly if I'm doing a side project, I can get up to speed with pretty much any language/framework and have it running in FAR less time than if I had to go through docs and set up my dev environment for said project.

There's really a lot to get from this "tool". Because in the end its a tool, and knowing how to use it is the most important aspect of it. It takes time, iteration, and practice to understand how to effectively use it
