1. BU does not cause bilateral fork. LEARN CONSENSUS
Yes it does cause a split. You are mistaken.
He is mistaken, but for different reasons. BU is a
unilateral split. If, after BU pulls the trigger on their hard fork, the Core chain
ever overtakes the BU chain,
all BU coins will be permanently destroyed and all transactions involving them will be forever invalid. Mass panic will ensue and their altcoin will be worthless.
That's why Core devs are begging BU to make their fork bilateral, but they won't listen (or they pretend not to listen because they don't have the competence to implement a bilateral fork).
if BU pulls the trigger.. it would do it with majority NODE (over50%) and majority hash(over 50%)
it wont trigger without consensus.
also all that occurs is a orphan which will inevitably and naturally find a single chain.
at a small majority (say 51-60%) just means clusterf*ck of orphan drama.
at a high majority (say 80-95%) just means less orphan drama
at superhigh majority (say 95%) just meand bearable amount of orphan drama, slightly above what happens daily anyway
just taking longer(more orphans) with lower amount of majority to get a single reliable chain
the only way to get the 2 chains to independantly survive is to intentionally ban communications with the opposition. which is what happened in ethereum
oh and emphasis on majority.. which also bursts your bubble of core overtaking lol (learn consensus please)
