Magic machine.
Even if such a magic machine were possible, can you imagine the size of the thing? It'd never be finished being built!
Whether or not it could be built (and whether or not, as a government I.T. project it could be built, which has a much more complex set of probabilities, but generally can be summarised as "no, no, fail, fail, lob another couple of billion tax money on the bonfire then scrap it until after next election"), such practicalities are not of any interest to the current political crop.
If they decide they wants it, it must be made to happen, and they'll keep on harping about it until they either get it or changes in technology/society/nefarious agenda result in a change in tack.
