Prototype for the plot of Terminator and other technodystopic iconographics. Tries to out-psych 1984, combining the classics (Vulcan's hammer? As in, those flying things were forging something?) with some shamelessly artless workmanship. It's all tediously first order; if two "sentient", mechanised intelligences are waging a proxy war on each other, wouldn't you expect the smarter one to figure out a robust winning strategy?
It seems pointless to read Dick now; his ideas have either been absorbed into the popular culture or are just dross, and I can't always tell. Some may argue that he got there first, but others have polished the product and gone deeper.
