This doesn't seem to be an issue with people I associate with, but that's because I'm older. Among the people I know who are in their twenties and thirties, they don't seem to be like this. They text more than I do, but they aren't doing it almost exclusively, and they are fine with speaking on a phone.
I do think that there is a major problem with communicating via text or email instead of talking directly to someone on a phone or in person. With text and email you don't get the person's tone or facial expressions. This can lead to miscommunication or hurt feelings. Emojis can help, but I have known people who received emails and took them in a way that was not intended.
Another example would be in a situation where you need to communicate about something that is a touchy subject, or you need to communicate with an acquaintance or relative that you aren't always on good terms with. I've seen threads on this site or on the old site where people were communicating with emails, and I would think that they would do better with a phone call.
