Are we supposed to be using BitCoinXT yet? I forgot when we are supposed to change, I'm lazy and haven't moved over or read about it.. I just don't want my 1 PH/s farm to abruptly work on the wrong chain.
No. That is never going to happen. Just keep mining with what you're used to.
I wonder why you didn't close this thread yet? XT is done, thus there is no need to discuss it.
BIP101 will continue to live on as long as people still believe in it. It can not die in the same way that Bitcoin can not die, so long as there are people that still believe in it, it will live on, it is the power of ideas. I am running several XT nodes myself, so my experience is a counterfactual to your declaration. It seems like some major players within the Bitcoin space now also support BIP101 so this is certainly far from done.
