Pope Benedict XVI has an interesting reflection on technology on his homily for Palm Sunday this year. You can read it in full here. He has spoken before on this issue. Below the most relevant points:
All the inventions of the human spirit are ultimately an effort to gain wings so as to rise to the heights of Being and to become independent, completely free, as God is free. Mankind has managed to accomplish so many things: we can fly! We can see, hear and speak to one another from the farthest ends of the earth. And yet the force of gravity which draws us down is powerful. With the increase of our abilities there has been an increase not only of good. Our possibilities for evil have increased and appear like menacing storms above history. Our limitations have also remained: we need but think of the disasters which have caused so much suffering for humanity in recent months.
The great achievements of technology are liberating and contribute to the progress of mankind only if they are joined to these attitudes – if our hands become clean and our hearts pure, if we seek truth, if we seek God and let ourselves be touched and challenged by his love.
