Hey, Mom! Talking to My Mother #648 - Brain has more than 100 times higher computational capacity than previously thought, say UCLA scientists
So, here's a thing. Banner week on the blog. Musical Monday, persuasive writing, a call the fire the White House Press Secretary, a nice Throwback photo, and then anti-semitism in comics. How could I follow that?
How about the question of when computers will exceed the capacity of the human brain?
I did a quick search, and I am not sure if I have written about this issue yet on my blog.
I teach a book called Radical Evolution at Western Michigan University. It's a shorter version of Ray Kurzweil's The Singularity is Near, which described four emerging technologies (GRIN - genetic engineering, robotics, information tech (AI), and nanotechnology, and how any one or a combination of these technologies could radically transform our lives, our world, and even our humanity, IE. what is means to be human and the definition of a human being.
This future prediction about these technologies has come to be known as the singularity, a term coined by originally by thinker and mathematician John von Neumann for technological progress of accelerating change. I have been misinforming my students that a gravitational singularity or a mathematical singularity, from where I assumed the name had been taken, is the same as a gravity well, like a planet or sun. Not so. Oops.
Gravitationally, a singularity is a "point" in space-time in which a gravitational field of a celestial body becomes infinite. Likewise, a singularity in mathematics is a point for which a mathematical object is not defined, as in it fails to be differentiable (discontinuity), one of which is an infinite discontinuity.
I guess this fits better the idea of the "singularity" as expressed in these books and "The Coming Technological Singularity" by Vernor Vinge because the progress could very well be infinite, which brings us to today's subject.
But, BTW, I made a video about these technologies. There's stuff specific to a class I no longer teach, but the description of the technologies is mostly correct, except for the gravity well part as I am just discovering right now. Hey, I can admit when I am wrong.
Here's the video:
So, today's blog post is about how close our technology (computers) is to meeting and/or exceeding the power, measured in computations (calculations) per second of the human brain.
Radical Evolution was written in 2005, at a time when a new IBM super computer, Blue Gene, would be able to do one quadrillon computations per second, much closer in order of magnitude to the human brain's then, supposed, ten quadrillon computations.
Today's article reveals that maybe the brain is even more powerful than that ten quadrillon mark. The article claims that the scientists studying the issue have discovered that the brain has about 100 times the capacity previously believed. Now, we're talking 1,000 quadrillon, or a quintillon (10^18).
The core of this discussion about computer capacity in the ability of the CPU to eventually match and then out pace the human brain is Moore's Law.
Moore's Law, created by Gordon Moore in the 1960s, claimed that computing power (computations per second) will double every two years (later reduced to 18 months) indefinitely.
This law describes an exponential curve without an upward bound, as in the power will keep doubling with no end in sight.
Here's some cool GIFs and graphics to express this idea and then the article about how scientists have just discovered that the brain is 100 times more powerful than previously believed.
I share all of this if for no other reason than I will direct my students here eventually.

Reflect and connect.
Have someone give you a kiss, and tell you that I love you.
I miss you so very much, Mom.
Talk to you tomorrow, Mom.

NOTE on time: When I post late, I had been posting at 7:10 a.m. because Google is on Pacific Time, and so this is really 10:10 EDT. However, it still shows up on the blog in Pacific time. So, I am going to start posting at 10:10 a.m. Pacific time, intending this to be 10:10 Eastern time. I know this only matters to me, and to you, Mom. But I am not going back and changing all the 7:10 a.m. times. But I will run this note for a while. Mom, you know that I am posting at 10:10 a.m. often because this is the time of your death.
