New technologies kill old gods and give birth to new gods. That’s why agricultural deities were different from hunter-gatherer spirits, why factory hands fantasised about different paradises than peasants and why the revolutionary technologies of the twenty-first century are far more likely to spawn unprecedented religious movements than to revive medieval creeds. Islamic fundamentalists may repeat the mantra that ‘Islam is the answer’, but religions that lose touch with the technological realities of the day forfeit their ability even to understand the questions being asked.
