It seems more than a little patronizing for Westerners to lament the loss of the good old days when life in the Khumbu was so much simpler and more picturesque. Most of the people who live in this rugged country seem to have no desire to be severed from the modern world or the untidy flow of human progress. The last thing Sherpas want is to be preserved as specimens in an anthropological museum.
A significant number of people believe tribal people still live and dress as they did 300 years ago. During my tenure as principal chief of the Cherokee Nation, national news agencies requesting interviews sometimes asked if they could film a tribal dance or if I would wear traditional tribal clothing for the interview. I doubt they asked the president of the United States to dress like a pilgrim for an interview.
