It’s fun to think about adhd re:tech, but a less fun hypothesis is that it’s something biological not yet identified.
Gov should do an annual sample computer-scored interactive test on 1000 5-year-olds to see adhd truly is increasing irrespective of increasing diagnostic criteria.
Some has already be done, in 2012 I think a team from harvard found biological markers which were identicals in patients suffering from autism/bipolar disorder/schyzophrenia and adhd and since adhd is a group of symptoms which can be caused by every "real" disorded listed above we found the biological something you mention.
