Texting is also damn convenient, I can deal with several conversations at once without having to pause the movie I’m watching.
Speaking on the phone doesn’t just tie your line, it ties your whole life too.
Another advantage of text, for me at least, is that I can read much faster than I can listen. This is why I prefer text articles to news videos, even though video can often offer extra visual information over what photographs can offer.
That said, I do somewhat agree with the article’s concern that live conversation is an independent skill and potentially has its own unique side-benefits that might be becoming rarer.
