The 'quiet quitting' that worries me the most is the one from citizens toward democracy all around the world. Brexit, Trump, and the rise of both abstention and extremism are clear signals of a real trend.
Initiatives in the digital democracy space (e.g. https://lnkd.in/g2YY57Bj or https://newvote.org/) and reports from organisations such as the Pew Research Center are promising. I believe Service and Product designers can play a big role but there is only so much that digital can do to address this systemic risk.
