Taste

May I spice up your argument with some sensory science trivia?

First, scent and taste are strongly interrelated:

Also, odor receptors aren't only in nasal passages. They are also distributed throughout the body: https://www.frontiersin.org/journals/aging-neuroscience/arti...

So sure, our sensory information- our sense of the world- is full of data that is so richly complicated, even the best achievable computational power may never fully grasp. And sure, each of us lives in a different reality based on very individual sensory responses.
