I think you can easily guesstimate how difficult something will be by listing the "new" stuff. But I think you can't easily estimate how easy something will be because you can't list everything, so anything you miss could easily delay. Said another way: We should have known it would take at least a decade, but should never have said it will take at most two decades. (as technologists). And yeah - agree - lvl 3 is pretty good, feature-wise.
