I don't know, maybe you cannot guarantee it -- similarly, you cannot guarantee the trustworthyness of Google, or Verisign, etc. They have good reputation in general (let aside the recent NSA stuff), therefore you trust them when you use them. Current systems can be broken as well (starting from DNS poisoning to hacking the actual service, etc.). The idea is not to fix all the problems once -- I'm mostly concerned with a) distributing responsibility, data and therefore power across more parties b) lowering barriers to entry into complex information processing, and as a result, increase innovation. A bit like a cathedral vs. bazaar approach. Again, I don't consider myself a computer wizard who could implement every aspect of this stuff; I am mostly interested in the algo that selects/evolves processing routes based on queries. But then there's the security, payment, service discovery, etc.
