Internet companies like Facebook or Instagram are still classified as technology companies for historical reasons, but technology is not driving them.
These companies are creating consumer services and the main deciding factor for their success is marketing and consumer behaviour. Innovations they do are just as technology oriented as new Nike shoes or Gillette razors. Technology is just in the background just like (chemical) technology is in the background of new shampoo or conditioner.
Back to the bubble. We are not in bubble. These prices are speculative prices in market share battle between companies that help to profile customers for marketing. In this market network externality (network effect) plays major part, so there can be only few global players. Companies like Facebook and Google must keep their checkbooks open and keep paying if they want to stay relevant. I would not worry about bubble until Facebook or Google start taking debt to pay for their acquisitions. Just like Microsoft was paying huge sums for companies just to drive them down to keep it's monopoly on PC markets for decades (while staying profitable all the time), Internet firms must do the same if they want to keep up their position in more volatile market.
It's true that all the information Google collects enables huge privacy infringement in scale that only Facebook can match, barely. I don't think for a second that Google as company is in any significant way better that others, but you must give it to Google that they at least initially tried. Some of that naivety is still there.
Quoting Defense Industry Daily article The F-35’s Air-to-Air Capability Controversy:
The core problem in Pacific Vision 2008 was that even an invulnerable American fighter force ran out of missiles before it ran out of targets, at any number below 50% of missile firings resulting in kills. Whereupon the remaining Chinese fighters would destroy the American tankers and AWACS aircraft, guaranteeing that the USAF’s F-22As would run out of fuel and crash before they could return to Guam.
To reiterate: RAND’s core conclusion is not about specific fighter performance. It is about the theoretical limits of better performance under adverse basing and logistics conditions. RAND’s Project Air Force argues, persuasively, that based on history and current trends, numbers still matter – and so does the “Lanchester square.” That’s the theory under which the combat performance of an outnumbered combatant must be the square of the outnumbering ratio (outnumbered 3:1 must be 9x better, etc.) just to stay even.
Or, as the oft-repeated Cold War era saying goes, “quantity has a quality all its own.”
Additional problem with F-35 is that it has limited missile carrying capacity, range, and stealth (stealth requirements were downgraded from very low observable, to low observable).
But we can save money. Soyuz program is the most successful launch platform by wide margin. It's safe, cheap, reliable and can launch frequently. Soyuz has over 1700 successful launches. It's the closest thing to "space truck" that there is.
Classical properties of money are: medium of exchange, unit of account and store of value.
Very few, if any, goods in bitcoin economy are sold using bitcoins as unit of account. Paying with bitcoin may be option, but goods are priced in other currency. Bitcoin prices are periodically adjusted to match price in other currency. Bitcoin clearly is not way to store value. Most people use it to speculate. Apart from limited use in paying small amounts of drugs for personal use etc. in local settings, bitcoin is not preferred medium of exchange. Because bitcoin is not used like money, it is not money. Currently bitcoin is just way to make payments (similar to debit or credit card) and speculative hobby for some.
Even very shaky third world currencies have some stability because people constantly need to buy them to pay taxes and fees. Only way I can see bitcoins becoming viable currency if some network communities or services would only accept bitcoins as payment. That would tie the value of bitcoin into something that has tangible value.
Correct me if I'm wrong, but Von Neumann architecture quantum computer is not very usable. There is not any way to program it in a usable way. Nor there is way to get results out.
The biggest problem with digital I&C is the “software common cause failure issue"
Imagine modern nuclear plant with multiple-channel redundancy in instrument and control systems, if one instrument fails, there are others. Same applies to whole cooling systems, if one cooling system fails, there are other completely independent systems that continue to work. Typically redundant systems use instruments from different manufacturers or instruments that are implemented with different technology.
This is not possible for digital systems because they are too costly to implement multiple times. What this means is that redundant digital control systems use same software. If one system fails because of software error, others may follow. This has already happened in German nuclear plant that had new digital system installed. Only the old analog system that was still operational saved the reactor.
This is why Finnish radiation and nuclear safety authority required changes in Areva's plans for the most modern nuclear reactor being build, Olkiluoto 3. They added analog safety requirements. Reactor must be able to shout down even when digital I&C has total failure. Relying for all digital systems compromises redundancy.

Best way to get everything right is to order desingn from company that specializes for control room design. Yokogawa is pretty good.
Special suggenstions for computer hardware:
- Monitors from Eizo. They just make the best monitors for control rooms, medical imaging, etc. http://www.eizo.com/global/
- Matrox graphic cards are really good for control rooms. It's their specialty and they exel in it. You can get multi monitor worstations that are silent http://www.matrox.com/graphics/en/
I'm a Finn. I know we fought well in WW2. It's what happened after the war that was submissive. It has even own word: Finlandisation
It all started after the war. Politicians knew that we would not be able to stand war against Soviets if we were the only enemy. They desided to play really really nice. Almost everything was OK as long as it did not involve Soviet troops in Finnish soil. It became liturgy to talk how good relations were between our countries. I think this was good idea at first. But then new generation of politicians grew, who thought that this good relationships bullshit was real. Soviets were able to influence our politics a lot. Finland censored talking, books and movies that were negative to Soviets. Some people even started to believe Soviet propaganda that we started the war.
The good part of all this was that we could keep our own economic system and democracy going (even if Soviets were able to mess with it from time to time). The cost of having western lifestyle next to Soviet Union was our pride. Cold war era was bad time for Finns.
Or you could just use Smalltalk, where any number that fits in a pointer-sized variable is stored like that and anything that doesn't is transparently promoted to an object.
That's implementation dependent, but I think most good Smalltalk and Lisp implementations do it like that. If you reserve two tags for immediate integers (one for positive, one for negative), you lose only two bits. Having 64-bit system, and memory access as bottleneck, that's incredibly good solution. Completely future proof solution even.
In 2001, FEMA warned that a hurricane striking New Orleans was one of the three most likely disasters in the U.S. But the Bush administration cut New Orleans flood control funding by 44 percent to pay for the Iraq war
For God's sake, stop researching for a while and begin to think!
