Humanity in jeopardy


If there’s even a 1% chance that there will be a Singularity in our lifetime, I think a reasonable precaution would be to spend at least 1% of our GDP studying the issue and deciding what to do about it.

January 13, 2014 by Max Tegmark

Exactly three years ago, on January 13, 2011, we humans were dethroned by a computer on the quiz show Jeopardy!.A year later, a computer was licensed to drive cars in Nevada after being judged safer than a human.
What’s next? Will computers eventually beat us at all tasks, developing superhuman intelligence?
I have little doubt that this can happen: our brains are a bunch of particles obeying the laws of physics, and there’s no physical law precluding particles from being arranged in ways that can perform even more advanced computations.
Risks vs. rewards of the Singularity
But will it happen anytime soon? Many experts are skeptical, while others such as Ray Kurzweil predict it will happen by 2045.
What I think is quite clear is that if it happens, the effects will be explosive: as Irving Good realized in 1965, machines with superhuman intelligence could rapidly design even better machines. Vernor Vinge called the resulting intelligence explosion ”The Singularity,” arguing that it was a point beyond which it was impossible for us to make reliable predictions.
After this, life on Earth would never be the same. Whoever or whatever controls this technology would rapidly become the world’s wealthiest and most powerful, outsmarting all financial markets, out-inventing and out-patenting all human researchers, and out-manipulating all human leaders. Even if we humans nominally merge with such machines, we might have no guarantees whatsoever about the ultimate outcome, making it feel less like a merger and more like a hostile corporate takeover.
In summary, will there be a Singularity within our lifetime? And is this something we should work for or against? On one hand, it could potentially solve most of our problems, even mortality. It could also open up space, the final frontier: unshackled by the limitations of our human bodies, such advanced life could rise up and eventually make much of our observable universe come alive.
On the other hand, it could destroy life as we know it and everything we care about — there are ample doomsday scenarios that look nothing like the Terminator movies, but are far more terrifying.
Other existential risks for spaceship Earth
I think it’s fair to say that we’re nowhere near consensus on either of these two questions, but that doesn’t mean it’s rational for us to do nothing about the issue. It could be the best or worst thing ever to happen to humanity, so if there’s even a 1% chance that there will be a Singularity in our lifetime, I think a reasonable precaution would be to spend at least 1% of our GDP studying the issue and deciding what to do about it. Yet we largely ignore it (a rare exception being intelligence.org).
Moreover, this is far from the only existential risk that we’re curiously complacent about, which is why I decided to dedicate the last part of my new book Our Mathematical Universe (http://mathematicaluniverse.org) to this very topic.
As our “spaceship Earth” blazes though cold and barren space, it both sustains and protects us. It’s stocked with major but limited supplies of water, food and fuel. Its atmosphere keeps us warm and shielded from the Sun’s harmful ultraviolet rays, and its magnetic field shelters us from lethal cosmic rays. Surely any responsible spaceship captain would make it a top priority to safeguard its future existence by avoiding asteroid collisions, on-board explosions, epidemics, overheating, ultraviolet shield destruction, and premature depletion of supplies?
Why are we so reckless?
Yet our spaceship crew hasn’t made any of these issues a top priority, devoting (by my estimate) less than a millionth of its resources to them. In fact, our spaceship doesn’t even have a captain!
Why are we so reckless? A common argument is that we can’t afford taking precautions, and that because it hasn’t been scientifically proven that any of these disaster scenarios will in fact occur, it would be irresponsible to devote resources toward their prevention.
To see the logical flaw in this argument, imagine that you’re buying a stroller for a friend’s baby, and a salesman tells you about a robust and well-tested $49.99 model that’s been sold for over a decade without any reported safety problems.
“But we also have this other model for just $39.99!”, he says. “I know there have been news reports of it collapsing and crushing the child, but there’s really no solid evidence, and nobody has been able to prove in court that any of the deaths were caused by a design flaw. And why spend 20% more money just because of some risks that aren’t proven?”
If we’d happily spend an extra 20% to safeguard the life of one child, we should logically do so also when the lives ofall children are at stake: not only those living now, but all future generations during the millions and potentially billions of future years that our cosmos has granted us.
It’s not that we can’t afford safeguarding our future: we can’t afford not to. What we should really be worried about is that we’re not more worried.

How to Digitally Record/Video a UFO sighting:


Como registar digitalmente ou gravar um vídeo de um avistamento de um UFO:




Stabilize the camera on a tripod. If there is no tripod, then set it on top of a stable, flat surface. If that is not possible lean against a wall to stabilize your body and prevent the camera from filming in a shaky, unsteady manner.

Estabilize a camera com um tripé. Se não tiver um tripé, então coloque-a em cima de uma superfície estável. Se não for possível, então encoste-se a uma parede para estabilizar o corpo e evitar que a camera registe de maneira tremida e instável.

Provide visual reference points for comparison. This includes the horizon, treetops, lampposts, houses, and geographical landmarks (i.e., Horsetooth Reservoir, Mt. Adams, etc.) Provide this in the video whenever is appropriate and doesn’t detract from what your focus is, the UFO.

Forneça pontos visuais de referência para comparação. Isso inclui o horizonte, cimo das árvores, postes de iluminação, pontos de referência geográficos (como o Reservatório de Horsetooth, Mone Adams, etc) Forneça esses pontos no vídeo sempre que for apropriado e não se distraia do que é o seu foco, o UFO/a Nave.

Narrate your videotape. Provide details of the date, time, location, and direction (N,S,E,W) you are looking in. Provide your observations on the weather, including approximate temperature, windspeed, any visible cloud cover or noticeable weather anomalies or events. Narrate on the shape, size, color, movements, approximate altitude of the UFO, etc and what it appears to be doing. Also include any unusual physical, psychological or emotional sensations you might have. Narrate any visual reference points on camera so they correlate with what the viewer will see, and thereby will be better able to understand.

Faça a narração do vídeo. Forneça pormenores sobre a data, hora, local e direcção (Norte, Sul, Este, Oeste) que está a observar. Faça observações sobre as condições atmosféricas, incluindo a temperatura aproximada, velocidade do vento, quantidade de nuvens, anomalias ou acontecimentos meteorológicos evidentes. Descreva a forma, o tamanho, a cor, os movimentos, a altitude aproximada onde se encontra o UFO/nave, etc e o que aparenta estar a fazer. Inclua também quaisquer aspectos pouco habituais de sensações físicas, psicológicas ou emocionais que possa ter. Faça a narração de todos os pontos de referência visual que o espectador irá ver e que, deste modo, será capaz de compreender melhor.

Be persistent and consistent. Return to the scene to videotape and record at this same location. If you have been successful once, the UFO sightings may be occurring in this region regularly, perhaps for specific reasons unknown, and you may be successful again. You may also wish to return to the same location at a different time of day (daylight hours) for better orientation and reference. Film just a minute or two under “normal” circumstances for comparison. Write down what you remember immediately after. As soon as you are done recording the experience/event, immediately write down your impressions, memories, thoughts, emotions, etc. so it is on the record in writing. If there were other witnesses, have them independently record their own impressions, thoughts, etc. Include in this exercise any drawings, sketches, or diagrams. Make sure you date and sign your documentation.

Seja persistente e não contraditório. Volte ao local da cena e registe o mesmo local. Se foi bem sucedido uma vez, pode ser que nessa região ocorram avistamentos de UFOs/naves com regularidade, talvez por razões específicas desconhecidas, e talvez possa ser novamente bem sucedido. Pode também desejar voltar ao mesmo lugar a horas diferentes do dia (durante as horas de luz)para ter uma orientação e referência melhor. Filme apenas um ,inuto ou dois em circunstâncias “normais” para ter um termo de comparação. Escreva tudo o que viu imediatamente após o acontecimento. Logo após ter feito o registo da experiência/acontecimento, escreva imediatamente as impressões, memórias, pensamentos, emoções, etc para que fiquem registadas por escrito. Se houver outras testemunhas, peça-lhes para registar independentemente as suas próprias impressões, pensamentos, etc. Inclua quaisquer desenhos, esbolos, diagramas. Certifique-se que data e assina o seu documento/testemunho.

Always be prepared. Have a digital camera or better yet a video camera with you, charged and ready to go, at all times. Make sure you know how to use your camera (and your cell phone video/photo camera) quickly and properly. These events can occur suddenly, unexpectedly, and often quite randomly, so you will need to be prepared.

Esteja sempre preparado, Tenha sempre uma camera digital, melhor ainda, uma camera vídeo consigo, carregada e pronta a usar sempre que necessário. Certifique-se que sabe como lidar com a sua camera (ou com o seu celular/camera fotográfica) rápida e adequadamente. Esses acontecimentos podem acontecer súbita e inesperadamente e, por vezes, acidentalmente, por isso, necessita estar preparado.

Look up. Be prepared. Report. Share.

Olhe para cima, Esteja preparado, Relate, Partilhe.
