Alright, good. We can agree on that.
You may be correct in that regard, but you shouldn’t base your opinion only on a popularized video. Quantum mechanics applies to any universe made of space, not just our own, so any universe of that type should have finite computing power available. What can be searched for is deviations from what the quantum math predicts we should see; computational short-cuts, as it were, such as if the granularity of space differs from what QM predicts. It’s still a new field, so you can expect disputes about the science (and it is science, and not theology as some interlocutors would suggest).
