Yes. Insofar as our brains are made up of physical matter and interpret electrical signals from our body. Emotions are our meat computers’ interpretations of some of those inputs. If you could know the exact location and velocity of every physical particle, you could know/predict the future based on that information and physics. It’s impossible to get that knowledge currently, but that doesn’t make the underlying principle any less true.

But I do agree that this is a dumb thing to argue abt and to let people enjoy their little thingies.
