It’s not just about primes, it’s about proving the technologies and techniques needed to verify such a number is prime, which might then be extrapolated to things unrelated to proving things prime.
For example, GIMPS (the organisation behind this find) was a great example of distributed computing long before people had multiprocessor supercomputers in their homes.
But let’s not forget the hobby factor. You don’t get to decide what other people do for fun. If they want to lend a portion of their computer’s runtime to a distributed computing project, that’s up to them.
Some people climb tall mountains, and that’s not of much use to anyone either.
My question is this: Do Microsoft ship crap-infested versions to people who could make their lives uncomfortable, like, say, intelligence agencies, or do those agencies take a crap-infested version and have their IT security strip all the crap out?
Because if I was in charge of an intelligence agency I’d be asking - with dangerous smile - for the crap-free version, turn IT loose on it anyway and then be, shall we say, horribly invasive to Microsoft if there’s anything still left in it.
… and if I wanted Windows, I’d want whatever the end result of that is.
On the other hand, maybe this has already happened and that “horrible invasion” is the cause of all the spyware crap in the consumer release.
Sigh.
