Fearfully and wonderfully made

From an article on the human brain:

A typical, healthy one houses some 200 billion nerve cells, which are connected to one another via hundreds of trillions of synapses. Each synapse functions like a microprocessor, and tens of thousands of them can connect a single neuron to other nerve cells. In the cerebral cortex alone, there are roughly 125 trillion synapses, which is about how many stars fill 1,500 Milky Way galaxies.

    That’s one of the reasons I think we are still many decades to maybe more than a century away from developing AI anywhere near the order of human brains. Or even an animal brain.

    We’ll get specialized AIs long before then, but AIs along the capabilities of the human brain? It’s gonna take a while, just from the massive scale needed just in the raw number of connections. There’s several other orders of magnitude issues beyond just the connections too, since nerves don’t operate on just the binary on/off system, but are more analog-based.

    Recommend you read “The Shallows,” by Nicholas Carr, subtitled: “What the Internet is Doing to Your Brain.” A very powerful book on the negative effects of the internet.

  • Sweet title for this blog post. God certainly likes to drive points home. This was the title of the Lutheran Educators Conference I just attended. Thanks for posting. God doesn’t want us to forget.

    Right on! So how could we ever hope to figure out the mind of the one who created not just such an incredible mind, but the universe and all life?

    One thing that scares me about this is, once they figure out how to program the brain-as-a-processing-system, will they create them simply to make use of their tremendous processing power? Sure would be cheaper than it’s equivalent in terms of computers, servers, routers, etc. etc. Could make copies via some kind of clone technology too, yikes!
