I agree with your conclusion though.
I can now travel into a city I’ve never been to, find directions to and make reservations at a popular restaurant, follow it up with directions to a nice scenic spot, and finally find a last minute nice hotel to stay in all without ever interacting with another person.
None of that was possible with radio/tv.
Very true. And not only information but 'stuff' as well: we buy (and now order) all sort of specialised tools that we will only need once, because they are now cheap and widely and quickly available, instead of borrowing them or asking a neighbour to come over with one.
But yeah, information availability is the main change: instead of asking a neighbour/friend where to get something, how to do something, how to choose something and so on, we browse the web alone for those pieces of information.
All this quickly brings more individualism since we become pseudo-self-reliant, do not need interactions any more, and since those 'forced', interested interactions are absent, the other interactions are lost too.
You life literally depends on what others think about you.
It still true for us, but an order of magnitude less after high school.
Your credit score does. In some places and situations, more directly than others.
Social connections require work, they also are slow and unreliable.
Before the information age, to get to know something, talking was the main way.
But now with books, panels, displays, packaging, signs, internet, GPS, etc., we have access to a huge quantity of information without having to talk to each others.
And we choose to do so because on average it's faster, more accurate, and avoid to deal with annoying people. After all, human relations also include a part of risk.
I lived 2 years in Africa, and there, you don't have that much information immediately available. You are back to talking, creating a social network and playing the game. People are way more friendly there, there is greater solidarity. But things are also way slower, unreliable, and you are a lot more at the mercy of popularity games even in the most simple activities.
This century we have been mutating our lives in deep ways, very fast. And it's not all bad. But we will need some time to reconcile the efficiency of our new life styles with the social needs we have at the primitive level. A few decades is way too short for that to have happened already, especially since we are not done with technical progress.
