"We learned that being first is important, but should not be the only factor when determining the viability of a project. If you have an evolved approach to a preexisting concept, you are likely doing something original and the results have a good chance of being meaningful." So, in one sense, it's another physical mirror. But: I like this point, that sometimes, you have to do a thing for yourself to learn about it. And by learning about it, you might ultimately differentiate your own work. As long as you don't claim you were first, there is no shame in doing what other people do. How else do you learn things? Not by other people yelling "OLD!" at you, that's for sure.
