Any signs community might grow/strengthen in the future?
Community and extended family are different things.
Community is a choice blood doesn’t specify. You can choose or find yourself lucky enough to live in a community that’s engaging. I live in a major US city. My particular block isn’t super engaging but I know, and am jealous of, a number of nearby blocks and neighborhoods that are incredibly supportive and engaging with each other - despite or in spite of the appearances or affiliations of the individuals.
Inversely, extended family may be more physically separated than in generations past. We’ve lost most connection with relatives in favor of the choice to live in an area that’s more advantageous to us - be it financially or spiritually or physically beneficial.
I’ve observed more instances of people establishing their own “extended family” through their communities. I’m not so sure there’s an inherent advantage of the extended family being made of blood or friendship.
Also, I’m not sure how you define “extended family”. I hang out with some of my first cousins all the time. Second cousins, not so much. Are aunts and uncles extended family - if not “nuclear family”? I see them too often, tbh.
