I am GenX. I would not roll back the internet. People look at their phones because they choose to look. Some are addicted, yes. It's their responsibility to recognize the issue and do something about it.
For example, I'm a software dev. I'm involved with the internet all day long. But I purposefully do not have an account for Twitter, Instagram, Faceplant, Truth, Mastodon, etc. I made a conscious decision not to engage there.
In other words, each individual GenX that prefers a world without screens has the ability to make that happen for their own life, and should do so.
