Massive ] parallelism doesn't help. Let's go for some nit-picking: the required effort is probably not multiplied by 2, but by a smaller "constant" (which still makes it exponential), or if you prefer, you have to add more than 1 bit (but still a constant number of bits) to multiply the required effort by 2.
