Aubergine. I'm guessing no one could have predicted that word would be next. If the universe is a deterministic simulation (of what?) that could be run backward and forward predictably, then of course the next word was always going to be "aubergine" with 100% certainty. In that case, all we need is the entire state of the universe to predict the next moment.
Maybe if we use a subset of English with a very specific set of rules to make it more deterministic? Some specific words or combination of words can have special meaning. And use symbols to make it a little bit easier to type the prompts and save on tokens/context size.
