There's a classic episode of The Twilight Zone where a guy survives the end of the world. He's happy because he's a huge misanthrope, and just wants to read books in solitude. The twist is he breaks his glasses, so even though he inherited his perfect world, he can't enjoy it.
Chantal will no doubt outlive us all. Once the very last cockroach dies, she will be momentarily happy that there are no more fat-shamers, twitter Karens, or fucking DEEDEEDOODOOs. But wait! There's also no Nader, no DoorDash drivers, and worst of all, no Beezers to hear her plaintive howls.
