I am sorry, but you are wrong. You cannot programmatically generate a
sequence of random numbers - this is a mathematical fact and has nothing
to do with discussions about brains and turing machines.
Secondly the 'ergodic' functions you describe _will_ produce the same
sequence every time they

Pseudo random numbers require a seed. Functional programs by definition

Thomas Davie writes, commenting my statement that one does need any
'stateful' (monadic, etc.) RN generator initializer within the program,
since you can always pass a parameter during its launching.
While I agree that it is often useful to start your program with different
parameters each time
