The purpose of technology should always be enhancing humanity, not being its substitute. If any new technology doesn't enhance our life in a positive way, it isn't worth developing.
Technology shouldn't be something that to be feared, but it should be something useful for people. All technological development should put peoples needs and interests first, so that it makes their lives better and enjoyable. It should be adding value to our lives, not subtracting from it.
People should be at the center of every technological development. There should be clear commitment to make the world a better, and how it'll meet that commitment. There shouldn't be any development just for the sake of doing so, just because something can be done doesn't mean it should be done.
The purpose of all and every technology is to be at the service of society. There should be no need to question this, and it should be the basis for all technological development. It doesn't mean that all development should be practical, in the sense that it should always come with something that can be sold or used by the masses.
It could help develop the skills of our children, or help us gain a better understanding of the universe by pushing the boundaries of knowledge even further.
Technology has brought us so this far, and it can still takes us places we can't even start imagining. That's why we should keep making it better, while making sure is at our service.
