Randal Koene makes a case for cyberbrains and why they needn't emulate the brain's hardware to run its software:
On August 18, IBM published an intriguing update of their work in the DARPA SyNAPSE program, seeking to create efficient new computing hardware that is inspired by the architecture of neurons and neuronal networks in the brain.
At carboncopies.org, we strive to take this research a step further: to bring about and nurture projects that are crucial to achieving substrate-independent minds (SIM). That is, enable minds to operate on many different hardware platforms — not just a neural substrate. And we seek realistic routes to SIM.
But what is it that those projects should accomplish?
