We are social beings. In fact, we cannot live in isolation. Yet, our society has been constructed to over rely on screen-based technology and keeping people in their homes alone.
We must build community centers at the local and city levels that can serve as public meeting places and forums. This sort of online forum is good, but part of the marketplace for ideas is that it is in person. We must be able to meet together and speak face-to-face. The Greeks did this in agora. There are no places today in US cities specifically purposed for people to go to in order to meet in a natural, open, free conversation.
Work with urban deisgners to make sure that local communities in urban areas have places to congregate in order to share and exchange ideas in a free and natural, non screen-based manner
