It's not a competition, except it sort of is: claiming to be the first as well as acknowledging previous is serious business in academia, and in an indirect way also an indicator of how much people did their homework or how willing they are to play nice with others. So if they don't view the demoscene as relevant previous work to their paper then I want to understand why they think their work falls under a different kind of procgen.
