Would online dating apps be needed if we had a bunch of free time, actual attachment to our communities, and a variety of activities that others would participate in?

Yeah I feel like that is the big question

plenty of people will still likely have anxieties and proclivities to staying inside / being shy

just because socialism gets rid of a lot of economic stress doesnt mean people cant be shitty anymore. there will still be abusive people that would make people anxious and stuff and drive people to online connections
