My 15-year-old stepdaughter went on a 10-minute-long explosive rant about how conservative politicians are retarded and seem incapable of doing math at a basic high-school level which ended with her storming off to write a "book on how they can do better that she will send to the governments". I could not have been more proud. She has even started expressing frustration with the amount of advertising that is going on and is coming to understand just how much information is taken from us every day.
If it's true that younger folks are more tech illiterate then Lemmy would be a non starter for them because it's more complicated to understand and use compared to centralized services.
