It's been downhill ever since. Allow entropy go on long enough and you could theoretically have all energy transferred from where it is to a great hyper-heated toxic dump in the sky, with the result that the whole universe would just burn up. Fortunately, there is still debate about this. Entropy causes enough problems as it is, such as the tendency in nature for things to move towards an equilibrium of disorder and towards a simple, inert state. Thus while we can easily burn wood in our fireplaces, no one has figured out how to take the ashes and turn them into a tree limb again, let alone recreate a whole rain forest.
Information theorists say entropy goes on in communications as well.
The repeated transfer of information results not in knowledge, they argued, but noise and static as the information degrades in its repetition, much as a fifth generation photocopy of a fax becomes unreadable. Cultures lose energy, too. Which is why the Egyptians don't build pyramids any more, and why Guatemalans have to import digital watches rather than just checking their Mayan calendars. The creation of a great civilization or a great world power wastes a enormous amount of energy. As Barry Commoner put it, in nature there is no free lunch.
