XT is a temporary solution, at best. Everyone understands that. Segregated witness is a better solution in the short run, and in the long run we'll have something else (lightning network?)
So XT does not make much sense, don't think they'll be able to pull it through
XT makes a great deal of sense...if the goal is to ensure that ultimately the last vestiges of infrastructure distribution among the masses are eliminated.
Hearn said semi-famously that '
there is no difference between confiscating someone BTC and keeping them from spending it for 20 years.' The numbers were just to be an illustration of a principle. The reason for he '20 years' rather than 'forever' is that some segment of the infrastructure might still be independent of a central blacklisting authority. Even now it is theoretically possible for a CPU miner to beat the datacenters full of ASIC in finding a block...it would just be really lucky and an exceedingly rare occurrence.
