3d Printing Will Never be a Thing

Or maybe it will. But it is still a technology in its infancy, not ready for prime time or novices. But for a Mashable writer who thinks that the future should be here now, that is somehow a valid criticism:

"How wrong we were. Instead of getting a cool case for our iPhones, all we got was a lot of headache. So much headache, in fact, that I'm now more convinced than ever that 3D printers for regular people will never become a thing."

The comments alone on this article show how shortsighted the author's criticism is, who even admits to not reading the manual. That's a red flag right there, that the technology might just be a little more complicated than a layman is ready for.

I'm still not sure why there is so much negativity toward 3d printing technology. Most of the complaints I see are from novices who think it should already be as simple as downloading a model, clicking print, then getting a perfect model a few hours later. Forget reality, I want it now!

The technology just isn't there yet, it's the realm of professionals and dedicated hobbyists, not laymen, yet. Given where it was five years ago, it's improving, but it's a slow progression.

I'm fairly technically proficient, and have a mind for CAD and 3d design, but actually getting something that prints and is useful for Betty homemaker on a $100 printer just isn't realistic yet, and that's the crowd that seems to be the most critical of the technology.

Personally, I'm still sending my models to 3d printing shops, waiting a few days and paying a few bucks, then getting a piece that I might have to do some filing or sanding to perfect.

And I'm fine with that. It's a realistic expectation of the technology and the level of investment required. Sure, eventually we may get to the point where we can send a model from the Web through a mobile app to a 3d printer in the garage and have it come out perfect every time, but for now let's try being a little realistic.

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.

Asimov's Bicentennial Timeline

Isaac Asimov thought logically in writing fiction, but could he have guessed that nearly 40 years later, the global population would have surpassed seven billion people.

　　It took time, but Andrew had time. In the first place, he did not wish to do anything till Paul had died in peace. With the death of the great-grandson of Sir, Andrew felt more nearly exposed to a hostile world and for that reason was all the more determined along the path he had chosen.

Asimov also took note of the corporate personhood movement that blurred the lines between individuals and collectives, and between man and machine. How can an immortal collective also be an individual, appreciating the same rights?

　　Yet he was not really alone. If a man had died, the firm of Feingold and Martin lived, for a corporation does not die any more than a robot does.

　　The firm had its directions and it followed them soullessly. By way of the trust and through the law firm, Andrew continued to be wealthy. In return for their own large annual retainer, Feingold and Martin involved themselves in the legal aspects of the new combustion chamber. But when the time came for Andrew to visit U.S. Robots and Mechanical Men Corporation, he did it alone. Once he had gone with Sir and once with Paul. This time, the third time, he was alone and manlike.

Toward the end of The Bicentennial Man, Asimov imagined that the Earth's population would have reached one billion, one hundred years or more from the story's beginning at the end of the 20th century.

　　U.S. Robots had changed. The actual production plant had been shifted to a large space station, as had grown to be the case with more and more industries. With them had gone many robots. The Earth itself was becoming park like, with its one-billion-person population stabilized and perhaps not more than thirty percent of its at-least-equally-large robot population independently brained.

The Tragedy of the Common Beach

I think that I have always known this, from my travels with my father to the reachea of North America. When property is owned in common, when it is public, few give enough concern to take care of it. Our recent family vacation to a Third Coast, third world beach reminded me of as much, that when there is no direct ownership of natural resources, exploitation tends to be common. 

We spent the first afternoon picking up trash, a big bag for each of us. When we wandered toward the more populated public beaches, I realized that even if I were tasked and emploed full-time to keep just a half-mile section clean, my work would never be finished. 

When one owns propert directly, there is an incentive to conserve resources, to protect the environment. When property is held in common, the inverse is true. Each has a perverse incentive to exploit resources at a competitive rate to other exploiters, further driving the quality of the resourcea into decline. 

Where's the beach? Its under the subsequent trash. 

Imagine that. 

What's actually in Taco Bell's meat? Cellulose, which you can't digest

What's actually in Taco Bell's meat?
    
There's something about Taco Bell's ground beef that has made some people wonder just what else might be in there. It turns out, the restaurant is pretty forthcoming with what ingredients are in its fast food items.

Cellulose: Cellulose is a safe carbohydrate found in the cell walls of plants and helps with water and oil binding. You'll find it in everything from cheese and vitamins to bread and pasta.

The human digestive system is incapable of processing cellulose, so it is essentially filler, plant pulp added to food stuffs to cut costs. Kraft uses insane levels in many of their products, so I would avoid eating anything that includes cellulose.
