This, essentially, is the summary of Homo Deus as a whole. We have embraced a liberal / humanist / capitalist society and from our point of view it’s hard to see how any other option could possibly be the ‘right’ one. By examining our history, we realise that nothing is fixed and we have the power, if we want, to shape the values of the future if we chose to do so.
