on: Email will last forever
Something is weird about email: Everyone can pretend to be someone else. It would be sane to reject all emails from a domain, that has no SPF record. I was asthonished when i realized that this is not already happening. Designing a large communication system it is just pure insanity to not include a sentence like this in the spec: "One can only send messages as one of the names he has power over." This could be ensured simply by SPF. It should be safe to assume, that a domain that has no SPF-record is not used for sending emails. I know that this is not the case right now, but it would change really fast, if you would push an update to the SPF-checkers, to enforce that rule. SPAM would be much less of problem than it is right now. Today you have to block ip-addresses, which is a large mess. With this rule enforced, you could block domains. Which are much harder to obtain and have a way smaller quantity.

on: A Conversation with Edward Snowden at HOPE X [video]
The big difference between the two is, that Edward Snowden realized that a positive vision is needed. Full respect for whistleblowing, but people need an alternative vision of society they can work towards. I would like to see more Hackers follow this approach of inspiring people to use technology to empower people. I mean we all know that evil things happen, so there is no point in repeating it all the time. The majority of people won't care. Especially here in germany the focus is way too much on influencing the world by talking. What Edward says goes in the right direction, but the vision is still too biased towards privacy concerned people. It's not about making encryption more accessable, it's about building great products people want to use and building encryption in as a byproduct. Lets take socialnetworks for example: Facebook is highly addictive, but without real value for the consumers. They don't want to connect the world, they want to generate adrevenue. It should be possible to build a platform where communication happens in a less perverted, self-centered way with encryption added on.
