This is very hyperbolic, everything in human history is a product of ‘artificial time’. You didn’t invent a hammer, or figure out how to read and write by yourself, or have to build a printing press to distribute messages, those were handed down to you.

Chess champions before Magnus would’ve had books of strategies to learn from as well, thereby benefiting from the time spent of players long gone.
