I don't think it's that apocalyptic.
Generations are made of individuals. Most of these people are of peasant stock, and in any generation, do what is useless. In fact, per the Dunning-Kruger effect, they think they're geniuses and do what is useless so they don't interrupt their own brilliance.
Generation Next, or X+3, because all generations post 1980 are apocalyptic "now we become Brazil" generations, will be more of the same -- slightly less informed, slightly less moral, slightly less alert -- except for the individuals in it who have a clue.
Those will go on, raise healthy families, and keep humanity going. The peasants will do what they always do: loaf unless forced to work, create landfill, have sex like monkeys and throw tantrums if anyone asks them to do anything productive.
