The Church views the person as primary, the most important, rather than the tools and applications of these tools. They see that technology and the use of technology forms people, it can literally change societies and people.

One example would be asking your buddies for a lift to the airport. Now we use an app. And then afterwards a year or two even thinking about asking your friends for a lift, or offering your friends to drive them is inappropriate and wrong. That reduces the connections between people, it reduces love.

A positive example would be the web2.0 social network, forums, message boards, communication increase. An explicit example is this submission, it's on the Vatican's website! A neutral example might be the medicine industry - new weight loss drugs improve the health of at risk people but at the cost of making them dependent on the industry and reducing personal agency in their change.

There are 2 main factors that the Church thinks wrt tech 1. Tools and technologies are not amoral, they have a moral component; against the argument of "this tech is innocent, it's how you use it". and 2. What we do, what we pay attention to, forms us. Our tools shape ourselves and the societies that we make us.

It's not anti tech, anti science or reactionary, it's pro person.
