You don't save them for the same reason that you don't necessarily save the state of the simulation after every state change. You're generating a lot of these things, conceivably billions and billions or more. Even if you do save that kind of data for the short term--be it the pseudorandom sequence or state changes or both--you may want to eventually delete it while still having the option of re-creating it at a later date. With a reproducible pseudo-random generator, you can do this by saving only the parameter settings and the seed value.
It's funny.  Laugh.

Miller looks out across America, which he can almost do from his 18th-floor office at Northwestern University Medical School in Chicago, he sees a landscape of haves and have-nots — in terms not of money, but of knowledge. Dr. Miller, 63, a political scientist who directs the Center for Biomedical Communications at the medical school, studies how much Americans know about science and what they think about it. His findings are not encouraging. Dr. Miller's data reveal some yawning gaps in basic knowledge. American adults in general do not understand what molecules are (other than that they are really small). Fewer than a third can identify DNA as a key to heredity. Only about 10 percent know what radiation is. One adult American in five thinks the Sun revolves around the Earth, an idea science had abandoned by the 17th century."

AISO.Net is one of a small number of hosts that use solar power to provide electricity for their data centers (as opposed to buying clean energy credits, a common practice among hosts that market their "green" operations). Even with the current focus on energy efficiency, using solar power for data centers remains a challenge due to issues with cost and capacity."
