'The end of history' is bullshit, we're currently stuck in a local minima, but nothing about this is essential or predetermined or necessary. This is the peak of nothing.
'It's easier to imagine the end of the world than it is to imagine the end of capitalism' is also bullshit. It's easy to imagine something better.
