The article is about how people into "futurism", like people over at /r/futurism or a large part of HN's userbase, keeps wishing people would stop "concerning" themselves with society and politics to bring technological future faster, have a big blind spot about what really matters and changes our lives.
G.K. Chesterton points out, in reply to the original manifesto:
Suffice it to say that Futurism has a gratifying dislike both of Liberal politics and Christian morals; I say gratifying because, however unfortunately the cross and the cap of liberty have quarrelled, they are always united in the feeble hatred of such silly megalomaniacs as these. They will "glorify war--the only true hygiene of the world--militarism, patriotism, the destructive gesture of Anarchism, the beautiful ideas which kill, and the scorn of woman." They will "destroy museums, libraries, and fight against moralism, feminism, and all utilitarian cowardice."
The essay fleshes this out in a less combative way, making less assumptions about what Futurists are for, and merely critiquing their blind spots.
