If part of your identity comes from maintaining connections through generations and if change happens quickly because nuclear families get smaller due to family break-up or generational estrangement, some young people may end up being disassociated from certain cultural values and perspectives and in the process traditions are lost or changed. This probably leads to people feeling a bit emotionally lost and disconnected in the process - while positives can come out of these processes of change, there are usually corresponding negative outcomes as well.
Some might seek to replace what is lost with something else to anchor themselves. The something else will need time to take hold in society and be tested and adapted as problems are identified and resolved and new problems emerge.
Individual nature/ nurture probably leads to some people feeling energised by constant change and flux and not requiring a place to land, or needing a sense of familiarity or a foundation, while others feel lost, adrift or even oppressed by the lack of security caused by constant change in social values. This could have unintended repercussions if people are looking for quick fixes or easy solutions to complex problems of identity.
