Let me put it this way: assume you have a full double-chest of every resource available and 10 of the biggest EU storage units available full of EU. What do you do with it?
Build an endgame base with teleporters between every room, a machine control panel that remotely turns on/off processing machines and indicator lights, a GT teleporter hub with destinations to all the important locations in my SMP world, a huge automated factory which takes input from a single chest tesseracted to all my advanced miners and sorts/processes them properly and precrafts a single chest of every conceivable resource for my AE to use, a sugarcane-powered fusion plant, a bee-powered fusion plant, a bee-powered SUC-reactor using redstone produced as a byproduct from my bee-powered fusion plant, a proper multifarm -> Ethanol setup that recycles all the cells and tesseracts the ethanol to LP boilers around the world for railcraft use, and powered by steam from the charcoal produced as well as the creosote waste, realize that my fusion reactors don't make enough plasma to provide EU for everything and build more, then run out of advanced machine casings because a double chest is really not that much, then set up more advanced miners to collect the resources necessary to finish this small part of my plans.
Seriously, minecraft is about the challenge of building and designing fun/effective things, not "crafting one of every machine until I get the highest tier machine, then quit and make a new world".
