The entire premise of the article seems to be based on the following paragraph and I simply did not understand it:

"In other words, the propensity for email, texting and quick-type apps has led us to forget some of our people skills, including distinguishing the nuances of language and meaning, fostering of a feeling of belonging among groups of people, and knowing our bosses and colleagues well enough to have confidence that others will pull their weight. That, in turn, has diminished implicit and earned trust among the people we work with."

How has has the use of quick-type apps eroded trust exactly? I don't follow this. Can anyone clarify?
