Philosophy and Human Transcendence

"So who am I? Since I am constantly changing, am I just a pattern? What if someone copies that pattern? Am I the original and/or the copy? Perhaps I am this stuff here—that is, the both ordered and chaotic collection of molecules that make up my body and brain."

Ray Kurzweil asks this question in The Singularity is Near. A classic metaphor, the Ship of Theseus, makes one wonder of we are who we were yesterday, or even last week.

"But there's a problem with this position. The specific set of particles that my body and brain comprise are in fact completely different from the atoms and molecules that I comprised only a short while ago. We know that most of our cells are turned over in a matter of weeks, and even our neurons, which persist as distinct cells for a relatively long time, nonetheless change all of their constituent molecules within a month.14 The half-life of a microtubule (a protein filament that provides the structure of a neuron) is about ten minutes. The actin filaments in dendrites are replaced about every forty seconds. The proteins that power the synapses are replaced about every hour. NMDA receptors in synapses stick around for a relatively long five days."

So will it be that unexpected when we merge with our technology to become God's? Arthur C. Clarke said that "Any sufficiently advanced technology is indistinguishable from magic."  Rest assured that what we may do someday would look like magic to us today.

The Future of Education is Homeschool

The future of education is homeschool, but it's not what you might think. In his book The Singularity is Near: When Humans Transcend Biology, inventor and futurist Ray looks at past trends in science, technology and even education, drawing natural conclusions about the course of progress in various fields and markets. He takes a very rational and systematic approach, careful not to delve into fantasy, but staying quite grounded in his analysis of what our futures hold.




For education, like many other facets of society, Kurzweil believes that we will see a decentralization as the technology improves. The persistence of a centralized model for a variety of industries, education included, was built upon a past that saw knowledge concentrated, resources inefficiently applied to challenges, and politics impeding progress.
As with all of our other institutions we will ultimately move toward a decentralized educational system in which every person will have ready access to the highest-quality knowledge and instruction. We are now in the early stages of this transformation, but already the advent of the availability of vast knowledge on the Web, useful search engines, high-quality open Web courseware, and increasingly effective computer-assisted instruction are providing widespread and inexpensive access to education. 
The future of education is likely to become not only destabilized, in a way that promotes the most innovative educators, but could see the institutions themselves shift toward a location-independent model where the students spend the majority of their learning time wherever they choose to call the classroom.
Most major universities now provide extensive courses online, many of which are free. MIT's OpenCourseWare (OCW) initiative has been a leader in this effort. MIT offers nine hundred of its courses—half of all its course offerings—for free on the Web.56 These have already had a major impact on education around the world. For example, Brigitte Bouissou writes, "As a math teacher in France, I want to thank MIT ... for [these] very lucid lectures, which are a great help for preparing my own classes." Sajid Latif, an educator in Pakistan, has integrated the MIT OCW courses into his own curriculum. His Pakistani students regularly attend virtually-MIT classes as a substantial part of their education.57 MIT intends to have everyone of its courses online and open source (that is, free of charge for noncommercial use) by 2007.
Since Kurzweil wrote The Singularity in 2005, not only have we seen online education come into its own, but institutions such as MIT realize the social value in bringing high-quality learning resources to the public for little to no cost. And they're not alone. There has been much hype surrounding the MOOC phenomena, but the long-term course seems to be more stable for these online education systems. Entrepreneurs are investing billions of dollars into underdeveloped regions.
The U.S. Army already conducts all of its nonphysical training using Web-based instruction. The accessible, inexpensive, and increasingly high-quality courseware available on the Web is also fueling a trend toward homeschooling.


As with much of Kurzweil's research, he often notes that as technology improves, costs fall, and society is better for it. He often notes The Law of Accelerating Returns in his research, that "we won’t experience 100 years of progress in the 21st century — it will be more like 20,000 years of progress (at today’s rate)." Each incremental improvement in cost or quality will come in less time and for less money than previous improvements. Costs for access to educational resources are continually falling, with technology spanning even physical divides, with learners in the most underdeveloped regions soon gaining access to the same quality education that can be found in developed regions.
The cost of the infrastructure for high-quality audiovisual Internet-based communication is continuing to fall rapidly, at a rate of about 50 percent per year, as we discussed in chapter 2. By the end of the decade it will be feasible for underdeveloped regions of the world to provide very inexpensive access to high-quality instruction for all grade levels from preschool to doctoral studies. Access to education will no longer be restricted by the lack of availability of trained teachers in each town and village.
Access will be guaranteed through low-cost technology and the entrepreneurship of innovators that understand that the way we have been providing services like education is based on outmoded models that have little place in the modern world.
As computer-assisted instruction (CAl) becomes more intelligent the ability to individualize the learning experience for each student will greatly improve. New generations of educational software are capable of modeling the strengths and weaknesses of each student and developing strategies to focus on the problem area of each learner. A company that I founded, Kurzweil Educational Systems, provides software that is used in tens of thousands of schools by students with reading disabilities to access ordinary printed materials and improve their reading skills.
The world is changing faster than ever before, and the future will make your head spin.

Sherlock Holmes on Discrimination

From Doyle's story A Case of Identity, reminding us that to discriminate is simply the act of making reasoned, informed decisions:

"I have seen those symptoms before," said Holmes, throwing his cigarette into the fire. "Oscillation upon the pavement always means an affaire de coeur. She would like advice, but is not sure that the matter is not too delicate for communication. And yet even here we may discriminate. When a woman has been seriously wronged by a man she no longer oscillates, and the usual symptom is a broken bell wire. Here we may take it that there is a love matter, but that the maiden is not so much angry as perplexed, or grieved. But here she comes in person to resolve our doubts."

Another great book focusing more on the act of making reasoned decisions is professor Walter Block's the Case for Discrimination, available from Mises.org.
