 In order to solve the most complex problems facing our society we have to address which of those problems we are to prioritize and I would argue from a human rights perspective that we need to focus on privacy and privacy in as much as how do we preserve freedoms in the way that we build our increasingly transforming societies. When we talk about smart cities, when we talk about contactless payments, when we talk about using the metro in a way where you just have to tap something instead of paying with cash. We are trading off our privacy and freedoms for convenience so it may be more convenient to live in a smart city where you can just kind of float through your day without taking anything out of your wallet but in that kind of sense you're reviewing everything about you to third parties whether they be governments, corporations etc. When we're at this frontier of the cashless society we have to think really carefully about what these new transformative technologies will do to our rights and freedoms.
