The entire MultiVerse stuff played out, which is loosely informed by real science theory on how we could indeed live in a multi verse of infinite realities seems to highlight one massive flaw in the actual scientific theory which i would be curious how they address it.
If indeed there are infinite parallel realities and Universes where everything plays out then what is the point of trying to change anything as even if you do, what you change in one is still going to completion in the next?
And i am not just speaking to comic book type play outs, but real life reality. Meaning even if you live the life of a bum you are also living the life the life of Elon Musk. If you change your life from being a bum, it does not change the other reality where you are still a bum.
In my view the Multi Verse reality scientific theory only really works if you assume we are all AI Sims, and the AI runs infinite sims as a way to gather data and learn. And the AI Sim theory is one that i do think has a very strong basis in scientific theory and is a credible theory, even if not a leading one.
