Copying the surface structure is normal. Every generation that follows the previous tends to copy the surface structure of its predecessors until they develop their own culture based on that generation's realities. Do you really think the culture of Silicon Valley of today is a facsimile of the culture of the 70's and 80's?

The thing to pay attention to isn't whether they're copying it exactly right, it's that they're copying the spirit and adapting it to their own circumstances.
