Detailed Brain Mapping Outlines What We Can — and Can’t — Know

Your brain, fully mapped, would take up a good part of the internet. And then it would just change again

Recently, a cubic millimetre (one millionth) of the human brain was imaged in sections via an electron microscope and found to contain 1.4 petabytes of data of nerve cells, blood cells, etc. A petabyte would be like taking over 4,000 digital photos per day through your entire life, as Monique Brouilette reports. But that wasn’t the big surprise: Cells were seen that were never seen in other animals, for example, “It is like discovering a new continent,” said Jeff Lichtman of Harvard, the senior author of the paper that presented these results. He described a menagerie of puzzling features that his team had already spotted in the human tissue, including new types of cells never seen in other animals, such…

Maps Are Not Territories and Reality Needn’t Follow Our Rules

These assumptions are just two more tales from the AI apocalypse, as George Gilder tells it, in Gaming AI.

Yesterday, we looked at two of the six assumptions that, according to George Gilder (pictured) in Gaming AI, are generally shared by those who believe that we will merge with our machines in a Singularity. These first two assumptions were: The brain is a computer and Big Data is a Big Answer. Now here are two more: • “The Binary Reality Assumption: Reliable links exist between maps and territories, computational symbols, and their objects.” (p. 50) Basically, this assumption means that reality will somehow always phone the computer’s map to say that things have changed. That assumption underlies the push for self-driving cars that can handle any terrain (Level 5). The machine is to handle all possibilities, including remote, unmapped…
