Joscha Bach: Artificial Consciousness and the Nature of Reality [video]
I was quite intrigued by semi-proposal of building a meta social network (it starts around 1:37:45). He proposes a service where anyone can start a social network using any features of existing ones (Facebook feed, Twitter conversation, Reddit threads...), with each network cultivating its own rules and reward function (criteria for what content is reshared or upvoted).On one hand it's over-ambitious and doomed to fail, and yet it could lead to more coherent and constructive hive mind.
