Why are there no longer front porches in fahrenheits 451 society?

In Fahrenheit 451, front porches are a symbol of community and human connection, which have been lost due to the dominance of technology and distraction. People in this society are more interested in isolating themselves with technology in their homes rather than engaging with their neighbors outside on front porches. This lack of community interaction contributes to the overall sense of disconnection and alienation in the society depicted in the novel.
