Living in a De Zerbi wonderland
I've never heard that theory but I have heard the one where life is just merely existence where there's no such thing as right and wrong. We can kill , we can hate, we can live in spite and we can do basically all that we like because all of this is just one big massive universal cock up created through a massive explosion.
What? Where did you hear that? It is true that there are no 'natural' consequences for our actions, and the universe doesn't care what we do... but that doesn't give anyone the right to do bad things without any consideration for morality and laws. I think your over simplifying the issue.
Also I'm surprised you've not heard of the simulation hypothesis. It's been widely reported over the last decade at least, as there is a view among some physicists that it's the most likely scenario for our existence. There are plans to devise experiments to prove one way or another which is correct, so we may find out at some point.
Elon Musk is a strong advocate of this view,

the computer simulation idea isnt taken seriously as its just a fantasy idea to base some films around, there's no actual science. as it supposes one universe and some form of virtual existence, its quite different from the many-worlds interpretatio. that is as expression of how to deal with the outcomes of quantum mechanics, in which we exist not just in this universe but an infinite number of parallel universes all slightly different.
And to answer your point, no, it's clearly more than a sci-fi idea. The films (Matrix being a well known example) were based upon the idea that we're all in a simulation. As I've said above, there are many scientists, philosophers and technologist who support this view.
