The present hegemonic doctrines of fundamentalist Islam are a product of "modern civilized society". The Iranian revolution was in 1979 (and Iran was a prosperous, modern industrial country at the time - it is not so prosperous these days what with sanctions and so forth).

Sayyid Qutb wrote Milestones in 1964, drawing inspiration from mass popular movements - religious and secular - of the 19th and 20th centuries. It is probably the single most influential text for Islamism (it was even, despite differences of sect, translated into Farsi by Khomeini, as I understand it). For Qutb, submission to Sharia law would unleash a new golden age of progress - it was secularism, rather, which was holding us back.

It's nonsense, yes. But it is modern nonsense. Separating modernity from the ongoing contestation of its meaning is the purest nonsense of all.

tl;dr - islamic fundamentalism is perfectly compatible with computers and stuff.
