Disclaimer: I am not a programmer, nor do I claim any familiarity with computer engineering/computer science beyond xkcd and having smart friends.
And as for the writing…
Overall, I don't feel like it's heading towards any particular direction. You tell us how powerful the computer is. You simulate the universe and prove the butterfly effect. You make the simulation be able to choose random decisions, which… I assume means giving the actors free will, and defeating the interesting philosophical point of a simulated universe being a deterministic one? Anyway, if you're making the simulation non-deterministic, why bother running an experiment with parallel universes?
Next, the last entry has entirely no precedent at all, and fails to instill in me any sort of emotion. Also, along the way, you hook up "the dialect of English" (which should've been inside the program since, you know, the universe contains English), and nothing of interest results from it. Whatever narrative is there, it's not cohesive or compelling enough for me to enjoy it, and the technical inaccuracies/lack of clarity pull it down even further. I'd suggest working on it being accurate and clear before working on anything else. There's nothing much else I can suggest unless you progress beyond that. For what it's worth, a technically-oriented tale that describes the consequences of having unlimited RAM (with limited processing power) would be a fun read, IMO.
