Look I can do a full list of errands and without having to say a single word to anyone.
1- I go to Sainsbury's for my weekly supermarket shopping and there are the self check-out tills. No questions asked I'm even working for the damn company scanning the items myself and packing them.
2 - Next I go to Boots same story
3 - And I need to post a letter to someone... Royal Mail... same story
4 - Next I'll pass by the library to fetch that book I reserved online. I go straight to the shelf...Scan the barcode and done.
5 - At night order a deliveroo and me and missus can have whatever we want from different food chains. Ah damn, I'll have to say to one word to the delivery guy: "Thanks mate!"
Yeah, we are more disconnected than ever, and it will only get worse.
problem is, people have less and less reason to interact with each other. Much of people's social anxiety probably boils down to lack of interaction. Like you say people don't even need to talk to workers on checkouts anymore. Those simple, small pieces of human interaction in everyday tasks are drying up. Its becoming increasingly abnormal to talk to people. I usually say "hello" to people when Im out and most of the time they just look at you like you are mentally ill.
Its probably a big reason why things like tinder have become so popular, people don't need to address their social issues but rather hide behind an app to meet people, its ideal, they dont even need to leave their house. The skill of learning to accept rejection is disappearing, tinder keeps it hidden from you, people have no idea how to approach someone in person, the concept is too terrifying, they want all of the reward and none of the risk. Again, approaching a person in a public place is becoming increasingly abnormal because no-one knows how to both do it and react to it.
one day it will probably end being like that "surrogates" movie where no-one leaves their homes except through the virtual reality of an android because people are both too terrified and too lazy to leave the house themselves.
people's laziness and desire for ease of use is isolating them from people, people dont even really physically interact with their friends and family anymore because of social media. Its really no mystery why loneliness is such a problem, people dont need to interact with people and when they do, they are so terrified of doing it that they try to avoid it. They just sit alone, looking into a phone at a edited version of someone's like wondering where they went wrong.
technology is amazing and has some really great advantages but it would be ignorant to ignore the clear disadvantages it is bringing upon people. Simple interaction is being lost.
