Summary: the computer has changed -- memory latency measured in CPU cycles has grown a lot. So we should not be using traditional struct/class-like programming model, where we put all properties of an object next to each other. Instead, we should be using game-style "data oriented programming" a.k.a. "column databases" for a much higher performance.
However, most modern languages (C, C++, Python, Java, etc..) are not making it easy, and this is bad! Meanwhile you can data into columns and enjoy faster programs.
