Adelaide AI pioneer says Terminator-like takeover unlikely

Posted by in categories: existential risks, robotics/AI, singularity

Apparently, Rodney Brooks, AI pioneer (@MIT CS & AI Lab; iRobot), is skeptical about artificial superintelligence:

“The difference between science fiction robots and real-life creations was the concept of robots being able to learn and teach themselves independently. A person can generalise, but we don’t have that kind of generalisation in any of these AI learning systems. So relax is my message.”

Or is he? This article by ABC Australia was focused on the same unfortunate meme, the unlikely Terminator which nobody has ever seriously suggested is realistic: “The Terminator series of movies foretold the future of humans and robots with Skynet becoming self-aware and launching its own nuclear war. But Professor Brooks said that was just science fiction.”

The Importance of Hope

Posted by in categories: biological, health, homo sapiens, life extension

I learn useful life lessons from each patient I meet. Some are positive messages, reminding me of the importance of maintaining balance between family, work, and leisure activities, but more frequently I witness examples of the remarkable resilience of the human spirit when facing the reality and risks of a major surgical procedure and a diagnosis of cancer. Rarely, patients and their family members utter remorseful or simply sad remarks when they are faced with a grim prognosis and the emotions associated with an onrushing date with mortality. These comments invariably involve an inventory of regrets in life, including, “I should have spent more time with my kids,” “I wish I had told my father (or mother, brother, sister, child, or some other person) that I loved them before they died,” and “I have spent my entire life working, I never took time for anything else.” I wince when I hear these openly expressed remonstrations, I recognize that I am hearing painful and heartfelt truths. Not a week goes by that I am not reminded that I do not one day want to look back at my life with a long list of regrets, should have dones, and what ifs.

I was blessed to meet a great teacher in the guise of a patient early in my academic career. He came to my clinic in my first year after completing a Fellowship in Surgical Oncology, my first year as an Assistant Professor of Surgery. My patient was a 69 year-old Baptist Minister from a small town in Mississippi. He was referred to me by his medical oncologist who called me and said, “I don’t think there is anything you can do for him, but he needs to hear that from you because he doesn’t believe me.” This tall, imposing man had colon cancer that had metastasized (spread) to his liver. The malignant tumor in his colon was removed the year before I met him, and he had received chemotherapy to treat several large tumors found in his liver. The chemotherapy had not worked and the tumors grew. At the point I met him, the medical oncologist told him he would live no more than 6 months, and because he was an avid fisherman when not preaching or helping others in his community , the doctor suggested that he go out and enjoy his remaining time by getting in as much fishing as possible. I learned two invaluable lessons from this patient and his family. First, never deny or dismiss hope from a patient or their family, even when from a medical perspective the situation seems hopeless and the patient is incurable. Second, quoting the minister directly, “Some doctors think of themselves as gods with a small ‘g’, but not one of you is God”.

Holographic Wormhole Drive: Breakthrough in “Warp Drive” Faster than light (FTL) Spaceship Design

Posted by in category: space travel

Older…thoughts?


Faster than light (FTL) space travel — the stuff of Science Fiction? Recent models require a Jupiter size negative mass-energy to operate. Now R. Amoroso has solved this problem in a radical new approach called the “Holographic Wormhole Drive”. — PR11498381.

Gene Editing Made Easier, Thanks to Carbon Nanotubes

Posted by in categories: bioengineering, biotech/medical, genetics, nanotechnology

In a new study, researchers detail the culturing and transfecting of cells with genetic material on an array of carbon nanotubes, which appears to overcome the limitations of other gene editing technologies.

Gene editing techniques hold great promise. They allow targeted and specific edits of genes, and have nearly limitless possibilities in the field of medicine.

Which is not to say that they are perfect. These techniques still have a range of limitations, from precision to toxicity. But a new study shows that can be changed.

Molecular mechanical computer design 100 billion times more energy efficient than best conventional computer

Posted by in categories: energy, supercomputing

Ralph Merkle, Robert Freitas and others have a theoretical design for a molecular mechanical computer that would be 100 billion times more energy efficient than the most energy efficient conventional green supercomputer. Removing the need for gears, clutches, switches, springs makes the design easier to build.

Existing designs for mechanical computing can be vastly improved upon in terms of the number of parts required to implement a complete computational system. Only two types of parts are required: Links, and rotary joints. Links are simply stiff, beam-like structures. Rotary joints are joints that allow rotational movement in a single plane.

Simple logic and conditional routing can be accomplished using only links and rotary joints, which are solidly connected at all times. No gears, clutches, switches, springs, or any other mechanisms are required. An actual system does not require linear slides.

Air force research lab roadmaps for game changing hypersonic vehicles, directed energy weapons and drones

Posted by in categories: drones, energy, military

Air Force Research Laboratory is working on key technologies in hypersonic air vehicles, directed-energy weapons and autonomy, or human-machine teaming, that will be “game-changers”

Air Force Research Laboratory scientists and engineers have developed an unarmed “cruise missile-like vehicle” that reached five times the speed of sound in tests, and have explored pairing drones with combat fighters in latest realm of technological advances.

Pentagon futurists envision a third-offset strategy to leapfrog U.S. technological capabilities to stay ahead of Russia and China.

Scientists can now make lithium-ion batteries last a lifetime

Posted by in category: nanotechnology

Who says playing around is a waste of time?

Researchers at the University of California at Irvine (UCI) said that’s exactly what they were doing when they discovered how to increase the tensile strength of nanowires that could be used to make lithium-ion batteries last virtually forever.

Researchers have pursued using nanowires in batteries for years because the filaments, thousands of times thinner than a human hair, are highly conductive and have a large surface area for the storage and transfer of electrons.
