Vitalik responses to a presentation at Deconomy

[Chaotic_4]

In the following video, Vitalik explains why Graig's presentation makes no sense I can understand some of his points however I can not hear everything and I don't understand everything because I am not familiar with all the terms and definitions. Could you please write down for me what he said? For instance, he is talking about the percent of the network which colludes with a miner, he calls that "kyano" or something? Also, he says "for NP-hard problem we can implement heuristic solutions which are..."   what?  ".....near-optimal in practice"?
