A sensationalist article title, for sure. My answers to the three "dangers" listed in the article:
No separation between home and work: in the late afternoon I shut down my computer and have a glass of wine and snacks with my wife. Work day is officially over.
The prevalence of distractions: earphones.
Lack of human interaction: I broke up my work day today by spending 90 minutes at our local shooting range with my wife and three friends. On Mondays and Thursdays I go on 2 to 3 hour hikes with several people. (Anyway, human contact is probably over rated :-)
The bottom line is that people should do whatever works for them. One caveat about working at home: you either really have to love your work or to have a strong work ethic.
