“What’s Mine Is Yours” is a book that reveals a powerful socioeconomic groundswell called "Collaborative Consumption" — traditional sharing, bartering, lending, trading, renting, gifting, and swapping redefined through technology and peer communities — that is transforming business, consumerism, and the way we live.
If the 20th century was defined by hyper consumption, the 21st century will be defined by collaborative consumption, according to Rachel Botsman. She defines collaborative consumption as being about "reputation, community and shared access" as opposed to "credit, advertising and individual ownership". It is about connecting to each other and sharing and exchanging all kinds of assets, including cars, skills and money.
One of the most important parts of collaborative consumption is trust between strangers. Social, mobile and location technologies are coming together to make efficiency and trust. Technology creates the social glue for trust to form between strangers. Sometimes the author mentions Collaborative Revolution, as a turning point where we use technology to reinvent entire sectors, and find a healthy balance of needs of individuals, needs of companies and the greater good of the society. This idea emerges the need to be “human again”, which means to lend/borrow real money to real people; to stay in real homes with real people. This kind of investment provides not only with the required service but also with a social connection, and this way man is back from virtual to real world. At the same time, they enable people to save money, time, and space; build closer relationships; and move from passive consumers to active collaborators.
Collaborative consumption has the power to revolutionize how we manage idling capacity, and by doing so change the way we view and become a part of communities in unique and meaningful ways.
