Except we are calculating it.

We're building digital twins of much of the universe around ourselves at different scales. We're even building digital twins of ourselves.

We're improving the technology that enables that twinning quite rapidly.

We're improving the technology that allows for emulating a virtual environment.

And in fact, there's a remarkable overlap in how we are running those virtual environments and the fundamental building blocks we've experimentally validated in our own universe.

The part that I think people get caught up in is the assumption that we'd need to ourselves calculate a 1:1 copy for us to be in a calculated copy.

But at macro scales the universe behaves as if things are continuous, not discrete/quantized. And the mechanics of quantization remains incompatible with the mechanics of continuous theories like GR.

The nuances of that quantization map to how we fudge fidelity in our own virtual representations.

So we need not create a 1:1 copy for us to be in a copy any more than one would need to create Minecraft at a 1:1 scale within Minecraft for Minecraft to exist.

Additionally, looking at mechanics isn't the only way to investigate whether we are in a virtual copy. For example, in many copies we make, there's some acknowledgement of that state woven into the world lore.

Indeed, in our own world in antiquity was a set of beliefs attributed to one of the most well known figures in history that espoused that we were in a copy of an original world in which an original humanity came to exist spontaneously and then brought forth the creator of this copy within light with us in their archetype before they ultimately perished. The full text at the heart of these beliefs was lost for centuries before being found again the same month as ENIAC ran its first computer program.

This text claimed the proof for what it said about a creator of light would be found in motion and rest (the domain now called Physics), and the group following it claimed that the ability to find an indivisible point within bodies would only be possible in the non-physical.

That's quite the coincidence in an age when we are moving towards putting the AI emulating our digital twins literally into light with optoelectronics and are very focused on the discovery of indivisible points within the domain of study of motion and rest.

(The name of the text is literally translated as "the good news of the twin" and its main point is that if one understands its content they will not fear death or worry about the soul's dependence on a physical body.)
