Civilisation peaked in 1940 and will collapse by 2040: the data-based predictions of 1973 - 0 views

  •  
    "In 1973, near the height of the 'population bomb' panic, a computing programme called World1 offered up some predictions for the future. It anticipated a grim picture for humanity based on current trajectories. Tracing categories such as population, pollution and natural-resource usage, World1 calculated that, by 2040, human civilisation would collapse - a century after the best year to have been alive on the planet: 1940. This film was originally broadcast by the Australian Broadcasting Corporation (ABC) News as part of a report on predictions for the coming decades made by cutting-edge computing technology and leading thinkers of the time. The second segment features interviews with members of the Club of Rome, an elite think tank composed of government officials, academics and business leaders focused on the future of humanity. Their view is a bit sunnier, anticipating a world where global governments are forced to cooperate to solve complex problems, people widen their cultural horizons and work fewer hours, and limited consumption - not wealth - becomes a mark of prestige. Viewed today, it makes for an engrossing artifact, raising far more questions than it answers about humanity's ability to effectively predict its future and correct its course."

Exxon Predicted 2019's Ominous CO2 Milestone in 1982 - 0 views

  •  
    "... The prediction is a pretty damn good one. The world is now about 1 degree Celsius (1.8 degrees Fahrenheit) warmer than it was and carbon dioxide levels are at 415 ppm. The estimate was part of Exxon's "high case" scenario, which assumed fossil fuel use would quicken and that the world would be able to tap new reserves in the late 2000s from at the time unreachable shale gas. The memo also warned that the extra carbon dioxide would enhance the greenhouse effect and that an "increase in absorbed energy via this route would warm the earth's surface causing changes in climate affecting atmospheric and ocean temperatures, rainfall patterns, soil moisture, and over centuries potentially melting the polar ice caps." Honestly, it gave me chills re-reading the memo 37 years later. The company clearly described all the horrors we're facing now. The only thing its scientists got wrong was that what they called "potentially serious climate problems" wouldn't emerge until the late 21st century. So much for that. ..."

1732: Earth Temperature Timeline - explain xkcd - 0 views

  •  
    "This comic is a timeline on how the temperature has changed from 20,000 BCE (Before Common Era) to the present day (2016), with three predictions for the rest of the 21st century depending on what actions are taken (or not taken) to stop CO₂ emission. This comic is a direct, but much more thorough, follow up on the previous global warming comic: 1379: 4.5 Degrees. By having readers scroll through millennia of slow-paced natural changes, Randall uses the comic to confront the the rapid temperature rise in the recent years. Over the past 100 years, human action has produced a large amount of CO₂ emissions, which have caused a rise in average global temperature through the greenhouse effect. This is called global warming and is part of a climate change, a subject that has become a recurrent subject on xkcd. There are still many people who claim that this is not happening, or at least that it is not caused by any human actions, called climate change deniers. One argument of theirs is that global warming is happening for natural causes, summarized with the phrase "temperature has changed before". "

The Computer Delusion - The Atlantic - 7 views

  • IN 1922 Thomas Edison predicted that "the motion picture is destined to revolutionize our educational system and ... in a few years it will supplant largely, if not entirely, the use of textbooks."
  • William Levenson, the director of the Cleveland public schools' radio station, claimed that "the time may come when a portable radio receiver will be as common in the classroom as is the blackboard.
  • B. F. Skinner, referring to the first days of his "teaching machines," in the late 1950s and early 1960s, wrote, "I was soon saying that, with the help of teaching machines and programmed instruction, students could learn twice as much in the same time and with the same effort as in a standard classroom."
  • ...39 more annotations...
  • a bridge to the twenty-first century ... where computers are as much a part of the classroom as blackboards
  • We could do so much to make education available twenty-four hours a day, seven days a week, that people could literally have a whole different attitude toward learning
  • Larry Cuban, a professor of education at Stanford University and a former school superintendent, observed that as successive rounds of new technology failed their promoters' expectations, a pattern emerged
  • Today's technology evangels argue that we've learned our lesson from past mistakes
  • The promoters of computers in schools again offer prodigious research showing improved academic achievement after using their technology
  • killed its music program last year to hire a technology coordinator
  • The possibilities of using this thing poorly so outweigh the chance of using it well, it makes people like us, who are fundamentally optimistic about computers, very reticent
  • Perhaps the best way to separate fact from fantasy is to take supporters' claims about computerized learning one by one and compare them with the evidence in the academic literature and in the everyday experiences I have observed or heard about in a variety of classrooms.
  • Computers improve both teaching practices and student achievement.
  • Computer literacy should be taught as early as possible; otherwise students will be left behind.
  • To make tomorrow's work force competitive in an increasingly high-tech world, learning computer skills must be a priority.
  • Technology programs leverage support from the business community—badly needed today because schools are increasingly starved for funds.
  • Work with computers—particularly using the Internet—brings students valuable connections with teachers, other schools and students, and a wide network of professionals around the globe.
  • Connecting K-12 Schools to the Information Superhighway
  • begins by citing numerous studies that have apparently proved that computers enhance student achievement significantly
  • n the early 1980s Apple shrewdly realized that donating computers to schools might help not only students but also company sales, as Apple's ubiquity in classrooms turned legions of families into Apple loyalists
  • there is scant evidence of greater student achievement.
  • They're especially weak in measuring intangibles such as enthusiasm and self-motivation
  • Computers in classrooms are the filmstrips of the 1990s
  • Apple quickly learned that teachers needed to change their classroom approach to what is commonly called "project-oriented learning
  • students learn through doing and teachers act as facilitators or partners rather than as didacts.
  • the guide on the side instead of the sage on the stage
  • But what the students learned "had less to do with the computer and more to do with the teaching,
  • Even in success stories important caveats continually pop up. The best educational software is usually complex — most suited to older students and sophisticated teachers.
  • Part of the answer may lie in the makeup of the Administration's technology task force
  • Each chapter describes various strategies for getting computers into classrooms, and the introduction acknowledges that "this report does not evaluate the relative merits of competing demands on educational funding
  • Hypertext Minds
  • Today's parents, knowing firsthand how families were burned by television's false promises, may want some objective advice about the age at which their children should become computer literate
  • Opinions diverge in part because research on the brain is still so sketchy, and computers are so new, that the effect of computers on the brain remains a great mystery.
  • that the mediated world is more significant than the real one.
  • n the past decade, according to the presidential task force's report, the number of jobs requiring computer skills has increased from 25 percent of all jobs in 1983 to 47 percent in 1993
  • told me the company rarely hires people who are predominantly computer experts, favoring instead those who have a talent for teamwork and are flexible and innovative
  • Many jobs obviously will demand basic computer skills if not sophisticated knowledge. But that doesn't mean that the parents or the teachers of young students need to panic.
  • NEWSPAPER financial sections carry almost daily pronouncements from the computer industry and other businesses about their high-tech hopes for America's schoolchildren
  • High-tech proponents argue that the best education software does develop flexible business intellects
  • IT is hard to visit a high-tech school without being led by a teacher into a room where students are communicating with people hundreds or thousands of miles away — over the Internet or sometimes through video-conferencing systems (two-way TV sets that broadcast live from each room).
  • The free nature of Internet information also means that students are confronted with chaos, and real dangers
  • We need less surfing in the schools, not more
  • chooling is not about information. It's getting kids to think about information. It's about understanding and knowledge and wisdom

    "Una nueva casta de gurús tecnológicos predica la inmortalidad, la felicidad eterna y la liberación del trabajo. Su "buena nueva" viene disfrazada de ciencia y financiada por grandes fortunas que pagan para que les cuenten lo que quieren oír. Pero las cosas quizá no sean como las cuentan los sacerdotes de la disrupción. Compartir en Meneame Enviar por email Comentar 33 19.07.2017 - 04:00 "Dentro de 20 años no habrá muerte, ni enfermedades, habrá tecnología para todos y desaparecerán los límites del conocimiento: nadie volverá a decir 'yo no sé'". Si usted cierra los ojos y escucha las palabras de José Luis Cordeiro podría llegar a pensar que está en misa, a punto de llegar al relato de la resurrección. Pero no está escuchando las promesas de un sacerdote o un predicador, sino del gurú tecnológico de moda, que va de evento en evento como miembro fundador de la Singularity University y hace todo tipo de promesas en nombre de la ciencia, algunas disparatadas. "Yo personalmente no pienso morir. Es más, pienso que en 30 años voy a ser más joven que hoy, gracias a los avances de la ciencia y la tecnología", aseguraba en su famosa entrevista con Iñaki Gabilondo en el programa "Cuando yo no esté". "Vamos a crear una civilización post-humana que va a ser casi igual a Dios"."
