Science and creativity
Development of good technology is obviously strongly based on science. But, it also requires a good deal of creativity. It is through the synergy of these two that the really interesting innovations evolve.
This is also a very important aspect of technology. And it is a difficult one, because it largely depends on culture. To me, however, there are obvious examples of unethical technology. The weapon industry is one. I think everyone agrees that no technologies in history has caused more human pain than those used to create weapons.
Not in the same league, but still largely unethical and potentially devastating for companies and organisations, are computer viruses and malware.
The good stuff
Luckily, the majority of technologies today are used to improve human life. And luckily, we are seeing an increasing global awareness. A will to share technology in order to develop countries in the third world and give people better lives. A will to develop technology that is sustainable and environmentally friendly, and prevent exploitation of our planet that is potentially life-threatening.
