Why is this useful? Well, the simplest application is quantum cryptography. A pair of entangled photons are the perfect channel for securely transferring a cryptographic key; due to the laws of quantum mechanics, it is physically impossible for someone to spy on the entangled photon. In the short term, a satellite-based quantum network is the kind of thing that governments would set up for secure communications.
In the long term, though, a quantum network could form the backbone of an internet populated by quantum computers. In theory, each quantum processor/computer connected to the quantum network could be instantly linked to every other computer via an entangled pair of photons.
Weman notes: "Companies like IBM and Samsung are driving this development in the search for a replacement for silicon in electronics as well as for new applications, such as flexible touch screens for mobile phones. Well, they need not wait any more. Our invention fits perfectly with the production machinery they already have. We make it easy for them to upgrade consumer electronics to a level where design has no limits."
Bio-technology is set then to be the next biggest technology, as food and medicine necessitates.
There are one or two challenges of course. The physics is mind-bogglingly complex and operates on a vanishingly small scale. So even using the world's most powerful supercomputers, physicists have only managed to simulate tiny corners of the cosmos just a few femtometers across. (A femtometer is 10^-15 metres.)
That may not sound like much but the significant point is that the simulation is essentially indistinguishable from the real thing (at least as far as we understand it).
It's not hard to imagine that Moore's Law-type progress will allow physicists to simulate significantly larger regions of space. A region just a few micrometres across could encapsulate the entire workings of a human cell.
Again, the behaviour of this human cell would be indistinguishable from the real thing.
It's this kind of thinking that forces physicists to consider the possibility that our entire cosmos could be running on a vastly powerful computer. If so, is there any way we could ever know?
STANFORD, Calif. — Scientists at Stanford University and the J. Craig Venter Institute have developed the first software simulation of an entire organism, a humble single-cell bacterium that lives in the human genital and respiratory tracts.
In recent writings, Vardi traces the evolution of the idea that artificial intelligence may one day surpass human intelligence, from Turing to Kurzweil, and considers the recent rate of progress. Although early predictions proved too aggressive, in the space of 15 years we’ve gone from Deep Blue beating Kasparov at chess to self-driving cars and Watson beating Jeopardy champs Ken Jennings and Brad Rutter.
Extrapolating into the future, Vardi thinks it’s reasonable to believe intelligent machines may one day replace human workers almost entirely and in the process put millions out of work permanently.
This paper claims that the “species dominance” issue will dominate our global politics later this century. Humanity will be bitterly divided over the question whether to build godlike, massively intelligent machines, called “artilects” (artificial intellects) which with 21st century technologies will have mental capacities trillions of trillions of times above the human level.
Humanity will split into 3 major camps, the “Cosmists” (in favor of building artilects),
the “Terrans” (opposed to building artilects),
and the “Cyborgs” (who want to become artilects themselves by adding components to their own human brains).
A major “artilect war” between the Cosmists and the Terrans, late in the 21st century will kill not millions but billions of people.
A drug vaccine for aids is going through human trials.
Now, Phase 1 trials (which started in March of 2012) are specifically to test if the vaccine is safe, and to identify any side effects (if any). It's not until Phases 2 and 3 that the actual effectiveness of the vaccine is truly put to the test. However, it seems that SAV001-H passed its Phase 1 trials with flying colours, since no adverse effects were reported in any of the patients that participated in the study.
When our natural human brains may only know accurately what 100 to 150 other human brains are doing what will society look like when some human brains know what of what most other human brains are doing?
Or when human brains may discern like a radio dial what type of context to infer from other various human brains at any time since human brains have been started to be being recorded?
Moore's Law states that the price of integrated circuitry falls exponentially over time. The tools of surveillance today are based on integrated circuits: unlike the grim secret policemen of the 20th century's totalitarian regimes they're getting cheaper, so that an intelligence agency with a fixed budget can hope to expand the breadth of its surveillance rapidly. In the wake of the events of September 11th, 2001, the inevitable calls for something to be done have segued into criticism of the west's intelligence apparatus: and like all bureaucratic agencies, their response to a failure is to redouble their efforts in the same direction as before. (If at first you don't succeed, try harder.)

All of us have some sort of "philosophy of life," even though we may not have verbalized it. Here you can get ideas for your own philosophy of life. You can see what others think of your own philosophical ideas, and you can help others to become clearer in their own thinking.
When there is difference of opinion, we have an opportunity for "friendly debate," a very growth-promoting experience.
