mano, sombra y niño

Increible, tan pequeño y sabe perfectamente reconocer una mano, solo de la sombra, calcular trayectorias y detectar peligros, esto último me parece menos asombroso.

Joder el cerebro humano no deja de sorprenderme.

Desempleo y nivel educativo

Hablamos de los efectos de la ola de automatización en el mercado laboral como algo que pasará en el futuro. En parte es así porque las estadísticas de desempleo se dan agrupadas. Pero si separamos las estadísticas por tramos y vemos qué pasa según el nivel de estudios, tenemos esto (los datos son de USA):

Osea, que tienes el doble de probabilidades de estar en el paro si no tienes ninguna formación universitaria que si tienes un título.

Pero sobre todo pensemos en los trabajos disponibles para gente con sólo la primaria: Fabricas, conserjerías y seguratas, limpieza, agricultura, hostelería, conductores...

Todo eso se está automatizando rápidamente.

Las fábricas cada vez contratan a menos trabajadores sin cualificar y a más trabajadores cualificados, que se ocupan de mantener la maquinaria funcionando.

A medida que vamos llenando todo de cámaras de vídeo, los trabajos de seguridad y de conserjería disminuyen.

Ahora casi todo se limpia con cacharritos, cade vez menos gente limpia más metros. Luego llegará un tío con una furgoneta por la mañana, descargará unos cuantos robots que limpiarán las oficinas y volverá a recogerlos para llevárselos al siguient edificio o planta.

En los restaurantes encargaremos la cocina con el teléfono y estará casi lista cuando lleguemos. Ocuparemos las mesas menos tiempo y el camarero no tendrá que tomar la nota ni cobrar. Total, menos camareros, y los camareros ya no necesitarán ni saber escribir, ni casi hablar, con lo que sería fácil reemplazarlos por bandejas automatizadas.

Los conductores empezarán a ver bajar la oferta de empleo en cuanto empiecen a poner vehículos autónomos en rutas fáciles de automatizar, que son las que hacen los conductores profesionales. Luego los furgoneteros, taxistas, etc...

La agricultura sigue su propio camino de automatización, que empezó con la revolución industrial.

Y ahora... qué haces con un chaval que no termina secundaria?

Carta abierta de Tsipras a los alemanes: Lo que nunca os dijeron sobre Grecia.

Esta carta la ha escrito y hecho pública Tsipras a través de la web de su partido. Básicamente viene a decir que la deuda no se puede pagar, que la política económica de la troika y de USA sólo sirve para retrasar y hacer mayor el problema, machacar a la gente normal, hacer más ricos a los ricos y mantener la cleptocracia en el gobierno.

Eso nos suena aquí, verdad? ahora la cuestión es si las élites deciden que no pueden tirar más de la manta y se avienen a negociar o si deciden dar un ejemplo con Grecia y hundirla del todo, por si a nosotros se nos ocurre ir detrás.


Most of you, dear [German] readers, will have formed a preconception of what this article is about before you actually read it. I am imploring you not to succumb to such preconceptions. Prejudice was never a good guide, especially during periods when an economic crisis reinforces stereotypes and breeds biggotry, nationalism, even violence.
In 2010, the Greek state ceased to be able to service its debt. Unfortunately, European officials decided to pretend that this problem could be overcome by means of the largest loan in history on condition of fiscal austerity that would, with mathematical precision, shrink the national income from which both new and old loans must be paid. An insolvency problem was thus dealt with as if it were a case of illiquidity.
In other words, Europe adopted the tactics of the least reputable bankers who refuse to acknowledge bad loans, preferring to grant new ones to the insolvent entity so as to pretend that the original loan is performing while extending the bankruptcy into the future. Nothing more than common sense was required to see that the application of the 'extend and pretend' tactic would lead my country to a tragic state. That instead of Greece's stabilization, Europe was creating the circumstances for a self-reinforcing crisis that undermines the foundations of Europe itself.
My party, and I personally, disagreed fiercely with the May 2010 loan agreement not because you, the citizens of Germany, did not give us enough money but because you gave us much, much more than you should have and our government accepted far, far more than it had a right to. Money that would, in any case, neither help the people of Greece (as it was being thrown into the black hole of an unsustainable debt) nor prevent the ballooning of Greek government debt, at great expense to the Greek and German taxpayer.
Indeed, even before a full year had gone by, from 2011 onwards, our predictions were confirmed. The combination of gigantic new loans and stringent government spending cuts that depressed incomes not only failed to rein the debt in but, also, punished the weakest of citizens turning people who had hitherto been living a measured, modest life into paupers and beggars, denying them above all else their dignity. The collapse of incomes pushed thousands of firms into bankruptcy boosting the oligopolistic power of surviving large firms. Thus, prices have been falling but more slowly than wages and salaries, pushing down overall demand for goods and services and crushing nominal incomes while debts continue their inexorable rise. In this setting, the deficit of hope accelerated uncontrollably and, before we knew it, the 'serpent's egg' hatched – the result being neo-Nazis patrolling our neighbourhoods, spreading their message of hatred.
Despite the evident failure of the 'extend and pretend' logic, it is still being implemented to this day. The second Greek 'bailout', enacted in the Spring of 2012, added another huge loan on the weakened shoulders of the Greek taxpayers, "haircut" our social security funds, and financed a ruthless new cleptocracy.
Respected commentators have been referring of recent to Greece's stabilization, even of signs of growth. Alas, 'Greek-covery' is but a mirage which we must put to rest as soon as possible. The recent modest rise of real GDP, to the tune of 0.7%, signals not the end of recession (as has been proclaimed) but, rather, its continuation. Think about it: The same official sources report, for the same quarter, an inflation rate of -1.80%, i.e. deflation. Which means that the 0.7% rise in real GDP was due to a negative growth rate of nominal GDP! In other words, all that happened is that prices declined faster than nominal national income. Not exactly a cause for proclaiming the end of six years of recession!
Allow me to submit to you that this sorry attempt to recruit a new version of 'Greek statistics', in order to declare the ongoing Greek crisis over, is an insult to all Europeans who, at long last, deserve the truth about Greece and about Europe. So, let me be frank: Greece's debt is currently unsustainable and will never be serviced, especially while Greece is being subjected to continuous fiscal waterboarding. The insistence in these dead-end policies, and in the denial of simple arithmetic, costs the German taxpayer dearly while, at once, condemning to a proud European nation to permanent indignity. What is even worse: In this manner, before long the Germans turn against the Greeks, the Greeks against the Germans and, unsurprisingly, the European Ideal suffers catastrophic losses.
Germany, and in particular the hard-working German workers, have nothing to fear from a SYRIZA victory. The opposite holds. Our task is not to confront our partners. It is not to secure larger loans or, equivalently, the right to higher deficits. Our target is, rather, the country's stabilization, balanced budgets and, of course, the end of the grand squeeze of the weaker Greek taxpayers in the context of a loan agreement that is simply unenforceable. We are committed to end 'extend and pretend' logic not against German citizens but with a view to the mutual advantages for all Europeans.
Dear readers, I understand that, behind your 'demand' that our government fulfills all of its 'contractual obligations' hides the fear that, if you let us Greeks some breathing space, we shall return to our bad, old ways. I acknowledge this anxiety. However, let me say that it was not SYRIZA that incubated the cleptocracy which today pretends to strive for 'reforms', as long as these 'reforms' do not affect their ill-gotten privileges. We are ready and willing to introduce major reforms for which we are now seeking a mandate to implement from the Greek electorate, naturally in collaboration with our European partners.
Our task is to bring about a European New Deal within which our people can breathe, create and live in dignity.

Si está en inglés, pero creo que tenemos el nivel suficiente para entenderlo (que no hace falta mucho); pero es que me he reido esta mañana tanto con esto que no me he resistido a ponerlo aquí:

Un paso mas en la electrónica casera

No tenía muy claro como llamar a esta entrada. Hay muchas apliaciones y utilidades para las impresoras 3D, según vayan afinando los cabezales, motores, sensores y filamentos la revolución es evidente para todos; para algunos mas que para otros, pero para todos.

Ahora bien, si con una impresora me imprimo mis propios objetos de eletrónica habrá muchos mas que verán que las impresoras 3D son la revolución sino que ya está aquí.

Aquí os dejo este vídeo que me encontré en Microsiervos


Por cierto en la misma entrada en Microsiervos, hay una referencia a otro invento que seguro va a ser otra revolución. Baterías imprimidas/impresas con una impresora 3D milagro posible gracias al grafeno.

¡¡Joder que bien nos lo vamos a pasar con todo lo que viene!!
