A neuron is analogous to a 3d integrated circuit rather to a transistor. A molecule acts like a transistor https://medium.com/the-physics-arxiv-blog/the-origin-of-life...

Changes in mechanical pressure, electric field, other molecules attachment, photon absorption, can control the conductivity.

Organic semiconductors designed to fit like lego bricks to naturally build the desired structure are IMHO the way to go to produce 3d circuits, rather than layered silicone litography.

I've seen this particular mistake a lot recently. New and exciting auto-corrupt from the latest version of iOS?

Given that our brains rewire themselves live, which ANNs can only do by being excessively connected and updating weights to/from zero, silicone (I'm thinking mainly the oil form) may be a better inspiration than lego.

Yes, puzzle pieces would be more accurate than lego.

The bonds that silicone forms do not AFAIK allow as rich variety of polymers as carbon.

Silicone, with the e on the end, is one of the main polymers.
