 According to the author, why do people stop themselves from sharing as much as they could?
People generally like to share what they create, but in a culture that tells them to be protective of their ideas, people start to believe in the danger of sharing. Much of their “culture” will be protected, but the net result is the direct loss of many other precious ideas, and the subsequent loss of all the potential gains of sharing.
