A High Risk But Viable Alternative to Kurzweil’s Singularity

December 7, 2016

Kurzweil’s Singularity consists of uploading the information in human biological brains into the silicon of computer hardware.  Kurzweil even regards this as possibly occurring during his own lifetime, so Kurzweil is doing everything possible to extend his life.  HM has previously indicated that this is highly unlikely because Kurzweil is ignoring the reality that silicon and biology differ.

The 29 October 2016 issue of the “New Scientist” has an article titled, “$100 million project to make intelligence-boosting implant.”  Entrepreneur Bryan Johnson launched the company Kernel earlier this year.  Johnson is working with Theodore Berger at the University of Southern California, who is looking at the hippocampus.  Healthy memory blog readers should know that the hippocampus is a key brain region involved in the retrieval of memories.  There is a hippocampus in each hemisphere, so we have two hippocampi.

Berger is working with people who already have electrical implants in their brains to treat epileptic seizures.  Instead of using these implants to stimulate the brain, his team has been harnessing them to record brain activity, to learn more about how our memory works.   Johnson says that once we know how a healthy brain functions, we should be able to mimic it.  The goal is to restore function in people with memory disorders by stimulating the same pattern of activity.  Berger has had enough success with animals that he has begun experiments with people.

Johnson says, “The idea is that if you have a loss of memory function, then you could build a prosthetic for the hippocampus that would help restore the circuitry and restore memory.”

It is both appropriate and fair that people with memory disorders will be the first to try the device.  Johnson says, “The first potential superhumans are those who have deficits to start with.”  He then plans to develop the prosthesis to enhance memory and potentially other functions in healthy people.  His vision of the future is one in which it is normal for people to walk around with chips in their brains, providing them with a cognitive boost.

Johnson has put up $100 million of his own to go on developing such a device.  It will be as tiny and easy to implant as possible, while still being able to record or stimulate multiple neurons.  The research also involved working on ways to develop rules that underly patterns of activity that dictate normal brain function for an individual.

Johnson says “If we can mimic the natural function of the brain, then I posit the question, what can’t we do?”  Could we learn a thousand times faster?  Could we choose which memories to keep and which to get rid of?  Could we have a connection with our computers?”

Note that Johnson is asking questions and not making promises.  To be sure this is high risk research, but it is one that is based on viable approach, unlike Kurzweil’s proposal.  Johnson has identified necessary first steps on the way to a marriage between the brain and silicon.

Computers in Our Brains

August 25, 2016

This post is based primarily on an article by Elizabeth Dworkin in the 17 April 2106 issue of the Washington Post titled “Putting a computer in your brain is no longer science fiction.”  It describe the research done by Silicon technology entrepreneur Bryan Johnson at his company Kernel, website is kernel.com.  It does not appear that Johnson has already put a computer into the brain, but rather is in the process of designing a computer to put into the brain.  The article also cites work by biomedical researcher Theodore Berger who has worked on a chip-assisted hippocampus for rats.  This work has yet to advance to humans.  And it probably will be many years before any fruits from this research will be realized.

This post is filed under transactive memory, which included posts on using external technology to build a healthy memory.  Now work is progressing on moving computer technology inside the brain.  Of course, anything that assists memory health will be welcomed.

An interesting conjecture is how this new technology would be used.  The statistics reported in the immediately preceding post made HM wonder to what extent people were making use of the biological memory they had.  It may be that when some people age their cognitive activity decreases.  And it may be that this failure to use it that is the primary cause of dementia.  This appears to be even more likely when there is evidence that people who have the defining physical features of Alzheimer’s never show any of the behavioral or cognitive symptoms.

So a reasonable question is how many people would benefit from computer implants?  It would be surprising if no one benefited, but it is not a forgone conclusion that everyone would benefit.  Some people might shut down cognitively even given a computer enhancements.  Of course, this is just a conjecture by HM.

HM would hope that people would still engage in the activities advocated by HM, to include growth mindsets, meditation, and mindfulness, in addition to general practices for personal health.
