It's not one-time pad encryption if you use data from a PSEUDO-random number generator. “One-time pad encryption” only applies when a true random stream is used

It's not one-time pad encryption if you use data from a PSEUDO-random number generator. “One-time pad encryption” only applies when a true random stream is used as key, otherwise it's just a block cipher with a particularly inconvenient way for the user to store the key. Or are you claiming that there's a risk in the future someone will find how to predict what output true random generators produced when they generated the key?
