Por qué el extraordinario invento de la electricidad fue tan decepcionante hace un siglo – El Mostrador

Recién en el año 2000, unos 50 años después de que se empezara a usar el primer programa de computación, empezó a subir la productividad. …E internet es aún más joven. Tenía apenas una década de existencia cuando explotó la burbuja .com. Cuando el generador eléctrico era tan viejo como lo es hoy la red, muchos dueños de fábricas seguían apegados al vapor.Los cambios grandes recién comenzaban a verse.La cosa que tiene una tecnología revolucionaria es que cambia todo, ¡por eso la llamamos revolucionaria!Y cambiar todo lleva tiempo, imaginación y coraje. Y a veces simplemente muchísimo trabajo.

Editor de The Economist anticipa en Chile la extinción de las actuales formas de trabajo ante la cuarta revolución industrial – El Mostrador

“Las computadoras han aprendido a conducir automóviles y entender el habla humana mucho más rápido de lo que anticipábamos que lo harían hace una década. Las capacidades que permiten a las computadoras hacer esas cosas también les permitirán hacer muchas otras tareas, ahora en manos de personas. Incluso si la inteligencia de la máquina mejora a un ritmo modesto en las próximas décadas, la cantidad de trabajo que pueden hacer las máquinas crecerá enormemente. Otro factor es, irónicamente, el estancamiento de los salarios. Veo un crecimiento débil en los salarios como evidencia que apunta a un exceso de mano de obra, donde es demasiado poco trabajo bueno”

Move over Dogecoin: the Herncoin is here. But what can making your own currency teach you about the world of bitcoin?

Bitcoin may have become a thing of fascination for the media very recently, but the digital currency actually celebrated its fifth birthday this month as its value hovered at around $1,000 per coin.

 

Bitcoin was never intended to be the one cryptocurrency to rule them all, because anyone can make their own version of it. The code which underpins the currency is released under what’s known as an open-source licence. Anyone can use it themselves, and alter any aspect they want, in order to create a whole new currency.

 

A whole class of alternative crypto-currencies, based on the fundamental aspects of bitcoin, have been created over the past couple of years. The first and biggest of the “altcoins”, called Litecoin, was created in 2011 to address some perceived flaws in the Bitcoin protocol.

 

Litecoin is much harder to build specialised “mining” machines for, which, according to its founders, prevents it from being dominated by a few rich miners. Additionally, it clears payments faster and has a much higher cap of 84m coins.

 

Since November 2011, Litecoin has tracked the value of Bitcoin fairly closely, but in December last year it spiked in value. Overnight, a Litecoin was worth 10 times what it had been before, and its total market cap now stands at $623m, around 16% of that of its parent.

The billionaire investor and libertarian thinker believes that in a world of government surveillance, more technology is the answer

Peter Thiel has only just sat down at a corner table in Palo Alto’s Evvia restaurant and he is already into a disquisition on the history of financial bubbles.

“This,” he declares, after listing the frequent market eruptions of the past three decades, “is historically very anomalous. There was one bubble in the 1920s and one in the 1720s.”

It is the sort of sweeping statement, delivered with flat finality, that Thiel thrives on. Since he has made billion-dollar fortunes twice over, in very different corners of the investment world (though one of the billions was promptly lost again), you’re inclined to give him the benefit of the doubt.

But you also can’t help thinking: really? What of the railroad bubble of the 1870s or the periodic booms and busts of capitalism’s gilded age? As with many of the eclectic assertions Thiel (pronounced “teal”) uses to pepper his conversation – allusions to Dickens and Shakespeare as well as the broad swaths of economic, technological and political history – you wish you could secretly Google under the table to fact-check.

Now the 46-year-old Facebook billionaire, former hedge fund star and self-styled libertarian Big Thinker is ready to declare one final bubble. This time it is the result of excessive government borrowing to refloat a world struggling to get beyond the financial crisis. With this, he argues, we have arrived at the Last Bubble. There will be no more. Period.

PC sales will suffer the “most severe yearly contraction on record” in 2013, falling more than 10 per cent as consumers switch to tablets and smartphones, according to the closely watchedInternational Data Corporation PC tracker.

Worldwide shipments of PCs are forecast to continue to fall next year, albeit at a slower pace, down 3.8 per cent to just above 300m, a level last seen in 2008.

Sales this year are forecast to fall even further than IDC originally expected, and more than the 7 per cent decline last year.

Consumers are rapidly abandoning desktops and laptops in favour of more portable devices, even in emerging markets, which had until now been a growth engine for PC sales. Total sales of PCs are expected to fall slightly more in emerging markets, than mature ones, IDC said.

Having seized 26,000 Bitcoins belonging to site users, authorities battle to control Ross Ulbricht’s personal wallet

The FBI has found that seizing an anonymous decentralised peer-to-peer currency was trickier than it seemed, following the Bureau’s bust of the international drugs marketplace, Silk Road.

When Ross Ulbricht, known as Dread Pirate Roberts to users of the site, was arrested last week, the FBI seized 26,000 Bitcoins belonging to Silk Road customers. But it also attempted, unsuccessfully, to claim the nearly 600,000 – thought to be worth around $80m – which Ulbricht himself is thought to be holding.

Bitcoin is a digital currency based on a methods of cryptography similar to those used to protect confidential emails. Due to its decentralised nature – the currency does not rely on any centralised agency to process payments, instead relying on work done by users’ computers – it is popular for a number of fringe-legal and illegal uses. One of those uses was Silk Road, where Bitcoin was required for all transactions.


A new digital ecology is evolving, and humans are being left behind

A new digital ecology is evolving, and humans are being left behind.

George Dvorsky

Wednesday 10:28am

Incomprehensible computer behaviors have evolved out of high-frequency stock trading, and humans aren’t sure why. Eventually, it could start affecting high-tech warfare, too. We spoke with a researcher at University of Miami who thinks humans will be outpaced by a new “machine ecology.”

For all intents and purposes, this genesis of this new world began in 2006 with the introduction of legislation which made high frequency stock trading a viable option. This form of rapid-fire trading involves algorithms, or bots, that can make decisions on the order of milliseconds (ms). By contrast, it takes a human at least one full second to both recognize and react to potential danger. Consequently, humans are progressively being left out of the trading loop.

And indeed, it’s a realm that’s rapidly expanding. For example, a new dedicated transatlantic cable is being built between US and UK traders that could boost transaction speed by another 5 ms. In addition, the new purpose-built chip iX-eCute is being launched which can prepare trades in an astounding 740 nanoseconds.

Virtual predators and prey

The problem, however, is that this new digital environment features agents that are not only making decisions faster than we can comprehend, they are also making decisions in a way that defies traditional theories of finance. In other words, it has taken on the form of a machine ecology — one that includes virtual predators and prey.

Consequently, computer scientists are taking an ecological perspective by looking at the new environment in terms of a competitive population of adaptive trading agents.
