Can metal remember?

I’ve mentioned in the past an idea that I freely concede may be crazy but it’s interesting enough to keep afloat: the possibility that consciousness is a basic property of all things and when matter interacts in complex and networked ways (like it does in a human brain or an advanced computer) higher, self-aware consciousness develops.

This L.A Times article offers more food for thought. It’s about a UCLA scientist who has developed a microchip that he claims can remember. How does it do it? Well, the science writing in this article is so vague that I’m pretty sure the reporter doesn’t understand and I sure don’t. It basically sounds like the scientist is creating neuron-like connections with metal strands and passing electricity through them.

In a lab, they placed a series of copper wire posts, mounted on a silicon wafer, into a solution of silver. As the copper dissolved, the silver formed intricate hair-like strands, as complex as the human cortex. It was the birth of the dust ball.

Building the chip is “extraordinarily simple,” Stieg says. Once the strands are created, they are exposed to sulfur, which provides electrical and ionic conductivity, and when electrical signals are sent through them, atoms migrate through each intersection of silver, each strand over strand.

Much as stimulus changes the brain by building over time synaptic patterns that can be associated to memory, the signals over time change the structure of the chip. Bridges form between the strands, further altering the chip.

What I find interesting here is the default behavior of the components of this chip seems to be to seek out “connections”, to create bridges. Much like neurons in the human brain branching and creating new synapses.

What causes neurons and silver strands to seek connections? I believe it is the fundamental need of all things to seek love!

No, seriously, I dunno. But if there’s a basic property of matter to, in some way, attract other matter, then it’s not that amazing that connections of the sort that could engender consciousness would arise.
