It's a vision to give one pause, not totally implausible.
In a near-future science fiction novel, human intelligence evolves into a hivemind that makes people the violent cells of a collective being.
Adam Roberts asks us to imagine a near future when electronic communications technologies enable groups of people to communicate with one another instantaneously, and on secure private networks invulnerable, or nearly so, to outside snooping. Imagine that such groups arise -- not created but self-organized and (at first) self-funding -- and are devoted not to radical Protestant Christianity but rather to radical democracy. And imagine one more thing: that such New Model Armies (NMAs) arm themselves and fight on behalf of those who pay them.
