Adulthood was going to happen with or without phones and internet. The only difference with phones and internet is you now have access to more than just the regional opinions and limited sources of curated news.

But to your point, without extended awareness that phones and internet give you, the ignorance that you are surrounded by absolutely horrible scumbags would be blissful.

However, flip side, you would likely never know your pastor rapes children and your dinner guests are Nazis. Not sure that is really bliss.
