"The democratisation of information has destroyed more young minds than Syphilis and Pinball combined!"
To put context on your 'Gen Z' assertion, as of Q3 2023, the average global screen time is approximately 6 hours and 40 minutes per day for users aged 16 to 64 - with most of that wholly attributable is due to a shift in the consumption from legacy to digital media, rather than an across the board increase in consumption.
The percentage of 12th graders who read a book or a magazine every day declined from 60% in the late 1970s to 16% by 2016, and 8th graders spent almost an hour less time watching TV in 2016 compared with the early 1990s. Trends were fairly uniform across gender, race/ethnicity, and socioeconomic status.

In the grand scheme of things, the Victorian invention of 'childhood' has been effectively pushed up to about 21-25 in most of the Western World as a consequence of ladder-pulling and the increasing training necessary for the Information Economy.
