but making computers backwards compatible is the reason why we are stuck with such trash personal computer systems, and every time microsoft tries to ditch outdated tech some idiots complain about not being able to use a 15 year old reporting application, because they like the graphical interface it offers better than current offerings they looked at. Not because of what it can do or how it does it. Everyone complains about MS making bloatware, but they only do it so there is enough backwards compatibility to keep enough of the people happy. (not that I often praise Apple, but...) Apple has it right by only supporting certain models when they release a new OS version, you have to ditch the crap if you want to progress to anything better. If we are lucky the next major OS releases from Apple and Microsoft will no longer come in 32 bit versions, considering a 32bit exclusive x86 CPU has not been manufactured for personal computers in the last 10 years.

Hopefully they will use such systems to help us design more efficient methods of doing the things we do today. No doubt someone will use one to "map the universe", I am sure they will be used to compute the math required to get a human to mars and back safely, in addition to predicting the survival rate of such a trip and able to recompute it with slight modifications in various conditions and time of year and planetary alignment.

I also expect them to be used to combat hackers

I would not be surprised at all if they are used to develop more efficient CPUs so that we can build bigger and better computers that can take over the world and remove the infestation known as humanity... yes I watch too many movies, but the real McCoy is in the books.
