We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Yes in fact. For example, Fermat's Little Theorem was developed during an examination of Prime Numbers and quadratic reciprocity was proven by Gauss. A mathematician named Volker Strassen discovered how to multiply more quickly using Fast Fourier Transforms while studying primes. These types of searches are also valuable for testing computer systems and components. You may remember the great Pentium bug which was found while testing with prime searches.
So there are uses albeit not for the everyday number cruncher.
