However, in addition to the observation that the communication modes or skills differ, the author makes the claim that the development of one mode/skill will produce deficiencies in the other. I don't think the author provides sufficient evidence that such an effect occurs, and I would further argue that such evidence would have to come from a more empirical rather than introspective source of knowledge (although for sure, personal experience would be what inspired the more rigorous experiment). My own experience is that quite opposite skill sets can and should be developed by individuals. Also from my own experience I would argue that knowing when to employ each different approach to communication is itself an important skill for hackers who use many different programming paradigms and technologies, as well as people who communicate with all different kinds of people (various subcultures of "creatives", scientists, academicians, business people, different socioeconomic/ethnic cultures). I think that being self-aware and well-developed is the key skill for both human-human and human-computer interaction.
