Let me explain what I mean. Some people say that Ben Franklin messed up when he named positive and negative charge -- that the charge which is on the electron should have been called "+" instead of "-". Imagine legions of physicists arguing back and forth over this issue, some vigorously defending "=" and others advocating for "-". It would all be wasted breath: they are just NAMES, and it doesn't MATTER which name you use. What matters is building a transistor, which depends on understanding that it's electrons that carry the charge, not on what the charge is called.
Similarly, any time that two MATHEMATICALLY equivalent theories both explain the facts, I personally don't care which one is true... I don't want to spend time debating it, and honestly I don't believe that one is more "true" than the other. Is classical mechanics driven by Newton's laws or by the Lagrangian "action is zero"? Both! Either one implies the other.
And this is how I view the question of whether the universe is a simulation. Finding out the laws of our universe seems interesting. Finding out whether those laws are implemented by a universe or a computer simulation of a universe... there is no meaningful difference so I don't care.
