how is "everything impossible" if "nothing is impossible"

shouldn't it be "everything is possible" if "nothing is impossible"?

it's not a paradox really, is it ?


also you are forgetting, quantum computers will in fact speed the arithmetic operations like cracking SHA but it will also bring new age encryption methods with which you can *tell* if someone opened the stream or not .... with all that "until observed" sort of thing... so i wouldn't worry yet. besides we're at least a decade away from commercial quantum computers.
