Is there any reason except being able to reproduce the same sequence of numbers, for using pseudo-random number generators while there is easy access to truly random numbers such as the number of milliseconds of the clock, the fluctuation in electricity, and etc...?
I heard that producing truly random sequence of numbers often takes more time and requires extra hardware, but the things I mentioned above shouldn't be like that.
So what are the other reasons that pseudo random numbers are so popular?
