Technology drives innovation in the modern world, but there is an innate nature in human beings to mistrust anything machine related. Interested in knowing what techniques are used to change this behavior. I heard all bad things about Cell Phones, Microwave ovens et al before adopting them; now these technologies are a major part of my life. What changed and how ? What were the techniques used to make this change by the manufacturers of these technologies ? Would appreciate any information in this regard.
