There’s an old Chinese saying– “Water can carry a boat; it can sink a boat”, and I think it can also describes technology perfectly. There’s no black-and-white judgement for technology, and in my opinion any innovation is neutral. It is human that makes the difference. For example, text message can be an excuse to avoid talking to someone(causing isolation), but at the same time it’s efficient to send quick and clear information(saving time). It all depends on how human use it.
But, I don’t mean that inventors don’t need to be aware of their doings. At least not in the vicious way. Inventors cannot control the usage of their invention by others, but at least they should, or try, to hold an intention to make this world better. Villains are not welcome to this world, sorry.
