To answers on this, I think the same way as Bruce Schneier:
GAZETTE: You’re one of the most well-known cybersecurity experts in the world. What do you do to protect your privacy online?
SCHNEIER: I don’t have any secret techniques. I do the same things everyone else does, and I make the same tradeoffs that everybody else does. I bank online. I shop online. I carry a cellphone, and it’s always turned on. I use credit cards and have airline frequent flier accounts. Perhaps the weirdest thing about my internet behavior is that I’m not on any social media platforms. That might make me a freak, but honestly it’s good for my productivity. In general, security experts aren’t paranoid; we just have a better understanding of the trade-offs we’re doing. Like everybody else, we regularly give up privacy for convenience. We just do it knowingly and consciously. ... Opting out doesn’t work. It’s nonsense to tell people not to carry a credit card or not to have an email address. And “buyer beware” is putting too much onus on the individual. People don’t test their food for pathogens or their airlines for safety. The government does it. But the government has failed in protecting consumers from internet companies and social media giants. But this will come around. The only effective way to control big corporations is through big government. My hope is that technologists also get involved in the political process — in government, in think-tanks, universities, and so on. That’s where the real change will happen. I tend to be short-term pessimistic and long-term optimistic. I don’t think this will do society in. This is not the first time we’ve seen technological changes that threaten to undermine society, and it won’t be the last.
