I don't know what will happen to the stalled BIP-110 chain and how successful will be blake2b mining. I myself cannot orange pill anyone else because when I did, I believed in the default game theory known to all. Clearly that is not the case anymore and 95% of the hash colluded to a solution that was not an attack on their position. There is no chance that they did not made a pact and with that, there is no way that it is not a 51% attack. SHA256 has been captured and it is lost to the game theory blake2b time will tell. But it is going to need a lot of time in the best of the scenarios
