premise: -- what weighs in that balance, because to go back for one second, in practical, economic terms I gather the difference between a copyright that lasts for 100 years, lasts for 1,000 years, lasts forever, is probably something less than 1,000 -- on $1,000 a penny.
hypothesis: Going back one second is important.
reason: It's never directly stated the importance of going back for one second, only what can be achieved. It's only implied that it's important, but it's not in the context.
