The building blocks for the torment nexus are mislabeled. Few people would be stupid enough to build the torment nexus if the labels were honest.
The building blocks for the torment nexus have many labels. Each one is desirable. This one says that no more children will be abused. That one says transportation will be cheap and fast. The one over there says that you'll get all you need without any work. Who would object?
Most people building the torment nexus don't care to torment anyone. Some believe they're building a better future. Others question a little, but they've got to feed their family, and questioning too hard makes it difficult. They're not evil. But the world is adversarial, and what can be used for advantage will be. Questioning is tiring, and life is hard enough. It's easier to be a cog.
Those who mislabeled the bricks, too, are rarely cartoon villains. Some are, but most are desperate for an edge, and if building the torment nexus will give them that edge, they're not so concerned about stepping on a few people to win. As long as the people getting hurt are abstract, it's ok.
And thus, the brick used to save children allows authoritarians to monitor and arrest journalists. The brick used for transportation demolished minority neighborhoods and put in freeways and misery. The brick used to end work ends negotiating power. By the time that people realize what they lost, protests will be safe to ignore. The economy will go on without workers. We're currently investing an awful lot into that last brick, looking for the next breakthroughs.
So, brick by brick, the torment nexus gets built. Brick by brick, people look at the labels, shrug, and ship them.
Are you building the world you want to live in?
