Almost certainly, "the brain" tunes itself to its environment and inner states from a preformed inner structure through evolution. A lot of what is in the brain, is not actually to be found in the brain, or by studying it materially. The "formwork" that formed it, is lost in evolutionary time.
Unfortunately there is no way to impute the formwork from the form, like say it would be possible to (mostly accurately) impute what formwork created a square column or cast a piece of iron.
"The brain" is not in any way shaped like a physical object, and the formwork that formed it is infinitely complex.
Our brains are physical object, and the connections it is composed of are also physical.

If that's who you are, there's no shame in identifying as so. Don't let hacker news comments gatekeep you.
For "inventory", it's just a custom state machine that can be scheduled in the past or future. And requests are things an area needs - which can be associated with an inventory item, or free text. This lets me pull up all requests when I'm at the store and see the kitchen needs apples, and the bathroom needs soap, etc.
Right now, I have a HUD for my front door (to remind me of things before i leave) a HUD for my phone/car (when I'm out) and then one for my kitchen, bathroom and hallway. I have the one in my kitchen magnetically on my fridge, so i can pull it off and take picture of food I'm adding. Will probably add one for my office next.
The difficult thing for me has been being the user more than being the builder and just focusing on the real MVP and then picking at it over time.
Working on cleaning it up and then maybe allowing others to give it a go - i feel like there could be some value in connecting people with spaces.
