Hypothetically speaking, lets say mining becomes pointless and way to difficult to do due to it getting harder and harder, and/or bitcoin peaks its mining limits.
What will become of the purpose built mining hardware? At the end of the day most hardware (KnC for example) cost well over $5,000, and their new one nearing $13,000, thats a lot of money whichever way you look at it, so my question is, what else could purpose built mining hardware be used for, other then mining of course?
It's just a question thats been on my mind, thats all.
