Actually you left something out, the PRNG by definition must have a
modulus of repetition. At some point it starts the sequence over.
In general, this is -never- a desired quality and is the primary
distinction between the cost-utility of PRNG's versus RNG's.
And on another statement by somebody about hardware v software RNG's:
If you can't develop a RNG in software (ie you'd be in a state of sin),
what makes you think you can do it using -only- digital gates in hardware?
You can't.
