It's increasingly looking like there are deep biological reasons for expressions like "gut instinct". There are a lot of neurons in the digestive system. A recent paper[2] appeared to show that the fundamental purpose of sleep is to regulate reactive molecules in the digestive system. Another item I saw in quanta, [or somewhere else][0], described how gut bacteria have a direct link to the vertebrate brain and immune system.

So my modest proposal is that if we want AGI, we need to figure out how to implement a digestive system in silico.

The problem is that whatever function digestion provides to the mind must do so through modulating neural signals. That is, its influence is purely functional in nature. Thus we can replicate its influence without replicating digestion, e.g. simulate the dynamics of the vagus nerve. There is nothing essential about digestion to consciousness.


The last sentence is a bit facetious.


With various embodied cognition or extended mind theses floating around, can't be too sure :)
