bitcoin 0.1.0 was deemed "production-ready" by satoshi.
and he subscribed to the same damn make blocks bigger and bigger scaling vision.
does that make him an idiot?
XT failed because poeple didnt like the idea that nodes on the network would eventually cost 1000's of dollars yearly to run should the network grow to visa like TX/sec, not because it was technically flawed. they see increased cost to nodes as having a centralizing effect. they are WRONG, but thats just my opinion... and few subscribe to it.
you small blockers like to pretend everything would come to a grinding halt if blocks were huge, ( some of you would say 2MB is "technically impossible") but thats not true, it just makes running a node more expensive
