I feel like while there always is some trust built in, that in the near future using a blockchain with special nodes that recieve rewards just like miners, but operate an exchange by having a node on each network and confirming exchanges between these cryptocurrencies (through proof of work or proof of stake) could be fairly trustless in the same way that Bitcoin is: that the computing power of the network is way too high for any single node to be able to scam you and steal the money you exchanged. Everything is trustful, even Bitcoin! You have to trust that the code is good and unhackable. While we will never eradicate having to have trust in our society, the blockchain has already removed a lot of it, and will in the future.

Thoughtful statements, @shredz7. This technology will enable us to choose more independently who or what we trust (computations, internet consensus, technology) instead of being forced to trust entities that do not have our best interests in mind (banks, government). It's a democratisation of trust, in a sense.
I agree that the trust does always have to be placed somewhere, just transferring it away from the ones who we are directly giving our value to is a good step and making sure they have enough incentive or prevention to not be allowed to abuse that trust is a huge step that crypto is solving.
