His study of machines arguably reflected both a delight in scientific advancement, and a fear of
the destructive capabilities of technology, in the wake of the nuclear stand - off and America's war in Vietnam.
Contemporary warfare has in fact taken the form
of local conflicts, more often than not civil wars, in which no great alliances
of nations are involved; these have been wars fought for reasons based in local rivalries, typically inflamed by historical animosities, ethnic disparity, or religious difference, rather than for reasons
of global Realpolitik; they have been fought not with nuclear weapons (or, indeed, other types
of weapons
of mass -
destructive capability) or the latest in military
technology, but instead with conventional weaponry, often
of old design, and often limited to rifles, knives, grenades, and light, crew - served weapons which individual soldiers can carry on their persons.
Yet we reckon with our own
destructive capabilities in extraordinary acts
of hope - filled creativity: we collect the DNA
of vanishing species in a «frozen ark,» equip orangutans with iPads, and create wearable
technologies and synthetic species that might one day outsmart us.
