Technologies: blessing or curse?

What do we know about present day technologies? Do they make our life easier or dangerous? Well, a century ago the only danger was a mechanical one but now we are at risk of being killed or injured by many technologically advanced devices such as cars, planes, nuclear plants, etc. Some people even predict that soon our world will be conquered by robots and we will be turned into slaves.

But I think that there are many useful things in our life that make it easy and enjoyable. For example, mobile phones (we can call from any place and know where our kids are), computers (delete all the borders), spy earpiece (can be very useful when you need some secret communication), and so on. I’m in favor of reasonable usage of modern technologies and I wouldn’t like to live at the end of the 19th century with no technologies.
