I disagree. Yes, there are tensions between openness/hackability/configurability/variability and stability/manageability/simplicity. However, the existence of certain tradeoffs doesn't mean that Apple couldn't make a more open product in some ways without hampering their much-vaunted quality.

One way to think about this question to analyze whether a given open/non-open decision is motivated by quality or by money. A great many of the design decisions that are being made are not in the pursuit of a perfect product, but are part of a business strategy (lock-in, planned obsolescence, upselling of other products, DRM, etc.). I'm not just talking about Apple, this is true very generally. Examples:
- Having a single set of hardware to support does indeed make software less bloated and more reliable. That's fair. Preventing users from installing new hardware (at their own risk) would not be fair.
- Similarly, having a restricted set of software that will be officially supported is fine. Preventing any 'unauthorized' software from running on a device a user has purchased is not okay. The solution is to simply provide a checkbox that says "Allow 3rd party sources (I understand this comes with risks)" which is what Android does but iOS does not.
- Removing seldom-used and complex configuration options from a product is a good way to make it simpler and more user-friendly. But you can easily promote openness without making the product worse by leaving configuration options available but less obvious (e.g. accessed via commandline flags or a text config file).
- Building a product in a non-user-servicable way (no screws, only adhesives, etc.) might be necessary if you're trying to make a product extremely thin and slick.
- Conversely, using non-standard screws, or using adhesives/etc. where screws would have been just as good, is merely a way to extract money from customers (forcing them to pay for servicing or buy new devices rather than fix old hardware).
- Using bizarre, non-standard, and obfuscated file formats or directory/data-structures can in some cases be necessary in order to achieve a goal (e.g. performance). However in most cases it's actually used to lock-in the user (prevent user from directly accessing data, prevent third-party tools from working). E.g. the way that iPods appear to store the music files and metadata is extremely complex, at least last time I checked (all files are renamed, so you can't simply copy files to-and-from the device). The correct solution is to use open formats. In cases where you absolutely can't use an established standard, the right thing to do is to release all your internal docs so that others can easily build upon it or extend it.

To summarize: yes, there are cases where making a product more 'open' will decrease its quality in other ways. But, actually, there are many examples where you can leave the option for openness/interoperability without affecting the as-sold quality of the product. (Worries about 'users breaking their devices and thus harming our image' do not persuade; the user owns the device and ultimately we're talking about experience users and third-party developers.) So, we should at least demand that companies make their products open in all those 'low-hanging-fruit' cases. We can then argue in more detail about fringe cases where there is really a openness/quality tradeoff.

I'm somewhat more hopeful than you, based on advances in x-ray optics.

For typical x-ray photons (e.g. 10 keV), the refractive index is 0.99999 (delta = 1E-5). Even though this is very close to 1, we've figured out how to make practical lenses. For instance Compound Refractive Lenses use a sequence of refracting interfaces to accumulate the small refractive effect. Capillary optics can be used to confine x-ray beams. A Fresnel lens design can be used to decrease the thickness of the lens, giving you more refractive power per unit length of the total optic. In fact, you can use a Fresnel zone plate design, which focuses the beam due to diffraction (another variant is a Laue lens which focuses due to Bragg diffraction, e.g. multilayer Laue lenses are now being used for ultrahigh focusing of x-rays). Clever people have even designed lenses that simultaneously exploit refractive and diffractive focusing (kinoform lenses).

All this to say that with some ingenuity, the rather small refractive index differences available for x-rays have been turned into decent amounts of focusing in x-ray optics. We have x-rays optics now with focal lengths on the order of meters. It's not trivial to do, but it can be done. It sounds like this present work is suggesting that for gamma-rays the refractive index differences will be on the order of 1E-7, which is only two orders-of-magnitude worse than for x-rays. So, with some additional effort and ingenuity, I could see the development of workable gamma-ray optics. I'm not saying it will be easy (we're still talking about tens or hundreds of meters for the overall camera)... but for certain demanding applications it might be worth doing.

I once decapsulated one of the first versions of these gate array. To my surprise a large fraction of the die area was completely unused - it seemed that the chip was extremely I/O limited. No wonder it was possible to fit further devices into that gate array.

Unfortunately the article is dumbed down a lot, so it is not easy to understand what technology is actually supposed to be used. But this sound a lot like a Rapid Thermal Anneal (RTA/RTP), which has been used for decades in semiconductor manufacturing. It has also been used a lot in lab environment to manufacture solar cells. It is possible that the energy consumption can be reduced, but the tool throughput and maintenance costs are quite a bit higher than that of a conventional furnace. I suppose that is why it did not catch on so far.

Nobium is not a rare earth element. It is however a part of coltan, which is a sought after mineral that is mined in congo and a major cause of civil war in that region.

Australia is extremely dumb when it comes to renewable energies and especially photovoltaics. Yes, it is that harsh. AUS has some of the most prolific research institutes in that area (The UNSW and the ANU) and provides ideal conditions for electricity generation by solar energy. Yet, they completely and utterly failed to capitalize on this aspect. There are no photovolatic companies of relevance in Australia and there are hardly any photovoltaic power plants.

The UNSW is now degenerated to educating recruits for chinese solar cell companies. Well done, Oz government, I hope sheep breeding and mining will be relevant for another century.

Yes, I was aware of these approaches of opening a band gap. I also recall a recent paper about field induced band gap opening. 250meV is not a lot, but it is a beginning. A band gap as small as this will still lead to serious junction leakage. Nowaday the ability to turn transistors off has become crucial; a major advantage of intels recently announced 22nm tri gate technology is that transistors can be turned off much more efficiently.

I don't think graphene transistors would require a significant investment. Apart from the tools to deposit the graphene, all other tools can be reused, provided that silicon is still the base material. Investing has never been a big issue for the larger companies.

But which applications involving carbon nanotubes are available on commercial scale today? I am only aware of it being used as (expensive) filler material.

CNTs are one of the topics which belong into the "pure science" realm. The main issues here are that no reliable method exist to separate metallic from semiconducting CNTs on large scale and that there is no reliable way of mass manufacturing CN transistors structurally.

Regarding graphene, there are at least methods to produce it on a wafer scale basis. The problem is, however, that despite the promising electron mobility in graphene, the electrical properties of graphene transistors are extremely bad. The latter is owed to the absence of a band gap and issues with junction formation.

Your response seems to suggest that you are qualified to answer the question I implied: Which application is going to remain when the next big thing comes up?

A few years ago all the rage was about carbon nanotubes. An entire generation of phd students was raised on this material. Carbon nanotubes were the material of the future, enabling the space elevator, nanoscale transistors, near-superconductor conductivity and so on. What is left today?

Even before that there were C60 buckyballs, another previously unnoticed carbon allotrope. Buckyballs were set to revolutionize chemistry and were (are) part of n-type organic semicunductors. What is left today?

A fad is a fad, even in science. Of all the imagined applications a few will remain, and will be turned into real applications by technologists and engineers. The scientists will move on to the next fad - well at least those who are quick enough.
