But vaguely, my guess is that if we compare long-range neuronal axons to metal wires, fiber-optic cables, or EM transmissions, we'd see, amortized over millions of connections.

Axons are in the same ballpark in terms of energy efficiency, but slower, lower bandwidth, and more voluminous.

This leads to, quote,

Method.

Add many millions of read-write electrodes to several brain areas, and then connect them to each other.

See Prosthetic Connectivity for Discussion of Variants and Problems.

The main problem is that current brain implants furnish less than 10 to the power of 4 connections, but greater than 10 to the power of 6 would probably be needed to have a major effect on problem-solving ability, and electrodes tend to kill neurons at the insertion site.

I don't know how to accelerate this, assuming that Neuralink is already on the ball well enough.

Human-human interface.

Quote.

Method.

Add many thousands of read-write electrodes to several brain areas in two different brains, and then connect them to each other.

End quote.

If one person could think with two brains, they'd be much smarter.

Two people connected is not the same thing, but could get some of the benefits.

The advantages of an electric interface over spoken language are higher bandwidth, lower latency, less cost, producing and decoding spoken words, and potentially more extrospective access, direct neural access to inexplicit neural events.

but it's not clear that there should be much qualitative increase in philosophical problem-solving ability.

A key advantage over prosthetic connectivity is that the benefits might require a couple ooms fewer connections.
