I don't get quantum computers. Why build one? What's the point?
They only talk about destructive purpuses: "with a quantum computer we can break this or that".
If it's only useful as a doomsday device, then stop trying to make one, dammit!
...starring Phil_S as President Merkin Muffley...Quantum computers will be built. Regardless of any particular entities' desire for such. (And despite whether or not their nature as
true quantum machines is real or imagined, which seems to be still a topic of some discussion) Technology has its own evolutionary imperative, to which we mere humans are only tools.
And to be able to deal with such eventuality -- and the implications thereof -- one must study such thingies. And in order to properly study such, one need be able to poke and prod an actual specimen of such. Hence the defensive need for such development, even if one is not interested in quantum computing for its own sake.
