Indeed, and I'm afraid it's only going to get worse - mostly because of those cell phones.
Furthermore, people are becoming less and less able to communicate face-to-face amongst one another. This is also notable in the workplace. I've seen a progression, or might I rather say a regression, of younger people in the workplace. I work in China, and this phenomenon seems very apparent for Americans under the age of 30 who come here for work; they have extremely poor communication and social skills and don't know how to handle even somewhat slightly challenging things that occur on the job. Plus, they are way too indoctrinated with Political Correctness, gender sensitivity and all that other crap they were fist fed in college. Sad.
