That doesn’t make sense to me. If someone wants to fool me that I’m looking att a tree he has to paint a tree in every detail. Depending on how closely I examine this tree he has to match my scrutiny to the finest detail. In the end, his rendering of a tree will be indistinguishable from an actual tree even at the molecular level.
In your dreams do you ever see trees you think are real? I doubt your brain is simulating the trees at a very high level of detail, yet this dream simulation can fool you.
Dreams exhibit many incoherencies. You can notice them and become “lucid”. Video games are also incoherent. They don’t obey some simple but extremely computationally demanding laws. They instead obey complicated laws that are not very computationally demanding. They cheat with physics for efficiency reasons, and those cheats are very obvious. Our real physics, however, hasn’t uncovered such apparent cheats. Physics doesn’t seem incoherent, it doesn’t resemble a video game or a dream.
This does not imply that the simulation is run entirely in linear time, or at a constant frame rate (or equivalent), or that details are determined a priori instead of post hoc. It is plausible such a system could run a usually-convincing-enough simulation at lower fidelity, back-calculate details as needed, and modify memories to ignore what would have been inconsistencies when doing so is necessary or just more useful/tractable. ‘Full detail simulation at all times’ is not a prerequisite for never being able to find and notice a flaw, or for getting many kinds of adequate high level macroscopic outputs.
In other words: If I want to convince you something is a real tree, it needs to look and feel like a tree, but it doesn’t need an exact, well-defined wave-function. Classical approximations at tens of microns scale are about the limit of unaided human perception. If you pull out a magnifying glass or a scanning electron microscope, then you can fill in little pieces of the remaining whole, but you still aren’t probing the whole tree down to the Planck scale.
