Humanity is definitely at a crossroads of deep ethical complexity, science and technology are apparently surpassing all human powers to be above society, but this is only apparently. Genetic transformation is already a reality, I do not doubt that we are able to modify human genes to obtain superior beings, they can be soldiers, sportsmen or mere mortals capable of resisting incurable diseases. I do not believe that we should fear the future of science and technology, the limits are not in these developments, the limits are moral. But we must be aware that science and technology are not neutral. Both science and technology respond to the interests of the social groups to which their creators respond, to the interests that financed their creation, to the groups that pay for the scientific complexes where they are produced. That is why we must not put limits to science and technology, the limits are in their creators, in the interests that are involved in the processes that create them. Science can and should be an ally of man to solve the problems of today. For example; Communication technologies bring people who are separated by great distances in an incredible way, today there are thousands of programs that allow us to "talk" with our family and friends who are far away. But paradoxically it distances people who are very close, today it is usual for people who work in the same office to send messages when they can talk to each other. It is a question of humans, of the way in which they conceive their social relations, of how they perceive the usefulness of technology. Humanity has to learn definitively that science and technology must be allies of its social development, of improving the quality of life of millions of human beings on the planet. Transgenesis must be an ally of man to overcome diseases, to produce more food, etc. What can not be is a weapon to put an end to genetic diversity, to end traditional crops, to provoke concentration of power in transnational corporations such as Monsanto, which is destroying small farmers in Latin America. It seems to me that the problem, independently that science and technology are not neutral, is in the way we use them and how they become levers for new developments.

Thank you Juan for great discussion. i wish see other people comments.

Muchas gracias por su reflexión, estoy convencido que el principio que hará posible la consolidación tecnológica y científica en el futuro es la ética.

JM...good dissertation.
