Yes, humanity is definitely degrading in every capacity. Think about Adam, the first man. He would have been an absolute genius compared to the smartest man or woman alive today. And Noah would've been a genius too, compared to the smartest people today (much less so after the Fall, but still he and Eve were probably the smartest people to ever live - except for that bit about eating of the fruit of the Tree of the Knowledge of Good and Evil). We have more advanced sciences and technologies available today, but that's only because we've built on the progress and successes of the many generations before us. Also, in the time frame since the Fall, we've lost knowledge and wisdom too. And rediscovered it again only much later or not at all. I'm not saying that Noah had laser tools or anything, but they could very easily (in terms of time and know-how) have created huge wooden cranes to build the Ark.
