No, young people do not have to be optimistic. They have to think with their own brain, and form their own opinions.

People in the 1980s were optimistic in technology because they didn’t have the chance to see the social upheaval that youth in the 2020s have grown with. Only a complete idiot would remain steadfastly optimistic after seeing what the rise of the internet, social media and mass surveillance has done in the name of this promised technological utopia. Only the sociopath would tell a young person to happily embrace AI in the worst economy in decades while headlines about AI-related job losses are everyday news.

Blind faith in anything leads to terrible outcomes, and that includes technology.
