I already have seen a massive decline personally and observationally (watching other people) in conversation skills.
Most people now to talk to each other like they are exchanging internet comments. They don't ask questions, they don't really engage... they just exchange declaratory sentences. Heck most of the dates I went on the past few years... zero real conversation and just vague exchanges of opinion and commentary. A couple of them went full on streamer, like just ranting at me and randomly stopping to ask me nonsense questions.
Most of our new employees the past year or two really struggle with any verbal communication and if you approach them physically to converse about something they emailed about they look massively uncomfortable and don't really know how to think on their feet.
Before the pandemic I used to actually converse with people and learn from them. Now everyone I meet feels like interacting with a highlight reel. What I don't understand is why people are choosing this and then complaining about it.
