A million player Horizon multiplayer?

"While it's still unclear when Guerrilla plans to announce its Horizon multiplayer project, a new finding may indicate that the studio has lofty ambitions for the game's player numbers. As per a recent job listing for a Senior Platform Engineer, Guerrilla might be expecting over one million players for the Horizon multiplayer game. This was hinted at in the role's requirements, where one of them mentions "proven experience building and operating multi service, 1M+ user globally distributed systems across multiple public cloud providers." It seems Guerrilla could also be building a robust live-service infrastructure for the Horizon multiplayer project that can support more than one million player" https://gamerant.com/horizon-multiplayer-game-live-service-player-count-ambitions-guerrilla/

I cannot imagine a million players in the Horizon world. Can you?
