Multiverse theory is the final realisation that your "choices" are statistically meaningless

If we suppose that the multiverse theory is true, then it is the ultimate blackpill because it renders your individual agency mathematically irrelevant. If every possible failure and success has already played out across a trillion timelines, your "choices" are no more than local hallucinations. THus you aren't the author of your life but the version of the algorithm that happened to land on these specific coordinates. Therefore your struggles are a rounding error in an infinite, indifferent calculation rather than a "hero's journey".
