(46) They were called "Luddites" after one of their leaders, a term that is now used for anyone who puts up resistance to new teclmologies. (47) The odd thing about nanotechnology’s Luddites is that they have started resisting before the technology has really established itself. As people start to buy products involving nanotechnology, from odour-resistant shirts to window glass that repels dirt, they will realise that many of these new things are useful and harmless. And as awareness of nanotechnology grows, they will begin to understand that it covers a range of different ways of doing things, some of which carry some risk and others do not. As a result, the technology’s detractors will probably become more nuanced in their complaints.
Nanotechnology has the potential to cause an industrial upheaval, just as electricity did in its tim
