Ian Hutchinson’s concerns for existential risk after minute 42.


Ian Hutchinson is a nuclear engineer and plasma physicist at MIT. He has made a number of important contributions in plasma physics including the magnetic confinement of plasmas seeking to enable fusion reactions, which is the energy source of the stars, to be used for practical energy production. Current nuclear reactors are based on fission as we discuss. Ian has also written on the philosophy of science and the relationship between science and religion.

“So a quantum key distribution consists of two things: No. 1, got to have a quantum random number generator, and that’s one of the things that QNu Labs makes,” he said. “The second thing that you need is the receivers in which those two devices connect and be used to convey encrypted messages in this fashion.”

In military use, quantum key distribution would work best in point to point communication — that is, communicating from one person to another. Creating a “true network” that’s able to send the same encrypted message to multiple receivers at once is challenging because the encrypted bit that’s carrying the message eventually begins to lose its coherence and “drops away,” Herman said.

“In the military, where you’re sending extremely sensitive classified data from one office to the next, you want to make sure that no one’s going to be able to break into and decrypt that,” he said. “Well, [quantum key distribution] is definitely a way in which to carry that out.”

“Almost every male character so far is a coward, a jerk or both,” he posted to Twitter. “Tolkien is turning in his grave.”

Amazon aired the first two episodes of Rings of Power on Friday, which centered on Galadriel, commander of the Northern Armies, bent on exacting vengeance for the death of her brother centuries earlier. By comparison, fellow elf Elrond prefers his life of quiet counsel to King Gil-galad, who attempts to send Galadriel away to avoid any military skirmish with Sauron’s scattered forces.

The debate over Amazon’s Rings of Power began in earnest after showrunners and studio executives argued in Vanity Fair they needed to take liberties when adapting Tolkien characters such as Galadriel and Elrond, since his Middle-earth was badly in need of an update to reflect today’s more modern societies.

CHILLING video shows the Chinese military unveiling more of their high-tech weapons as tensions continue to rage with the West.

Beijing flaunted its military tech in the new video which shows a machine-gun armed robot dog, a small ball scout drone and a soldier wearing an exoskeleton.

It is understood the technology is made by Chinese defence firm Kestrel and the clips from the exercises were shared on Beijing’s state-monitored social media site Weibo.

Practical nuclear fusion is, famously, always 10 years in the future. Except that the Pentagon recently gave an award to a tiny startup to launch a fusion power system into space in just five.

There is no shortage of organizations, from VC-backedstartups to nation states, trying to realize the dream of cheap, clean, and reliable power from nuclear fusion. But Avalanche Energy Designs, based near a Boeing facility in Seattle, is even more ambitious. It is working on modular “micro fusion packs,” small enough to hold in your hand yet capable of powering everything from electric cars to spaceships.

Last month, the Pentagon’s Defense Innovation Unit (DIU) announced it had awarded Avalanche an unspecified sum to develop its Orbitron fusion device to generate either heat or electricity, with the aim of powering a high-efficiency propulsion system aboard a prototype satellite in 2027. The contract to Avalanche was one of two awarded by the DIU—the second going to Seattle-based Ultra Safe Nuclear for development of its radioisotope battery.

Title: Strong AI: Why we should be concerned about something nobody knows how to build.
Synopsis: At the moment, nobody fully knows how to create an intelligent system that rivals or exceed human capabilities (Strong AI). The impact and possible dangers of Strong AI appear to concern mostly those futurists that are not working in day-to-day AI research. This in turn gives rise to the idea that Strong AI is merely a myth, a sci fi trope and nothing that is ever going to be implemented. The current state of the art in AI is already sufficient to lead to irrevocable changes in labor markets, economy, warfare and governance. The need to deal with these near term changes does not absolve us from considering the implications of being no longer the most intelligent beings on this planet.
Despite the difficulties of developing Strong AI, there is no obvious reason why the principles embedded in biological brains should be outside of the range of what our engineering can achieve in the near future. While it is unlikely that current narrow AI systems will neatly scale towards general modeling and problem solving, many of the significant open questions in developing Strong AI appear to be known and solvable.

Talk held at ‘Artificial Intelligence / Human Possibilities’ event as adjunct to the AGI17 conference in Melbourne 2017.

Assessing emerging risks and opportunities in machine cognition.

With AI Experts Ben Goertzel, Marcus Hutter, Peter Cheeseman and Joscha Bach.

Event Focus:
Given significant developments in Artificial Intelligence, it’s worth asking: What aspects of ideal AI have not been achieved yet?
There is good reason for the growing media storm around AI — many experts agree on the big picture that with the development of Superintelligent AI (including Artificial General Intelligence) humanity will face great challenges (some polls suggest that AGI is not far). Though in order to best manage both the opportunities and risks we need to achieve a clearer picture — this requires sensitivity to ambiguity, precision of expression and attention to theoretical detail in understanding the implications of AI, communicating/discussing AI, and ultimately engineering beneficial AI.

It is still a fraction of the resources it can dedicate to the fight.

On February 24 when Russian troops began crossing over the border of Ukraine, little did anybody think that the conflict would go on for months. With a massive advantage of the sheer number of troops, military equipment, and technology, the Russian ‘special operation’ should not have even lasted weeks.

The infrared (IR) spectrum is a vast information landscape that modern IR detectors tap into for diverse applications such as night vision, biochemical spectroscopy, microelectronics design, and climate science. But modern sensors used in these practical areas lack spectral selectivity and must filter out noise, limiting their performance. Advanced IR sensors can achieve ultrasensitive, single-photon level detection, but these sensors must be cryogenically cooled to 4 K (−269 C) and require large, bulky power sources making them too expensive and impractical for everyday Department of Defense or commercial use.

DARPA’s Optomechanical Thermal Imaging (OpTIm) program aims to develop novel, compact, and room-temperature IR sensors with quantum-level performance – bridging the performance gap between limited capability uncooled thermal detectors and high-performance cryogenically cooled photodetectors.

“If researchers can meet the program’s metrics, we will enable IR detection with orders-of-magnitude improvements in sensitivity, spectral control, and response time over current room-temperature IR devices,” said Mukund Vengalattore, OpTIm program manager in DARPA’s Defense Sciences Office. “Achieving quantum-level sensitivity in room-temperature, compact IR sensors would transform battlefield surveillance, night vision, and terrestrial and space imaging. It would also enable a host of commercial applications including infrared spectroscopy for non-invasive cancer diagnosis, highly accurate and immediate pathogen detection from a person’s breath or in the air, and pre-disease detection of threats to agriculture and foliage health.”

Google employees are ratcheting up pressure on the internet-search giant to abandon its artificial intelligence work with the Israeli government, planning public demonstrations to draw greater attention to the controversial cloud-computing contract.

A handful of current and former workers spoke on Wednesday alongside Palestinian rights activists in San Francisco to call for the Alphabet Inc.-owned company to end Project Nimbus, a $1.2 billion contract through which Google and Amazon.com Inc. provide the Israeli government and military with AI and cloud services. The seven-year contract went into effect in July 2021. A petition protesting the agreement has received 800 signatures from Google employees, according to one of the organizers.

WASHINGTON — The Defense Advanced Research Projects Agency said it selected teams to help develop an on-orbit satellite communications translator within just eight days of releasing a formal solicitation. Now, the Pentagon agency charged with making investments in transformational technology wants to apply that quick approach to other programs.

DARPA announced last month that 11 teams would participate in Phase 1 its Space-Based Adaptive Communications Node program, dubbed Space-BACN, an in-space terminal designed to help government and commercial satellites communicate.

The capability is increasing in relevance as companies such as SpaceX and organizations including the Space Development Agency launch large constellations of satellites to low Earth orbit, within 1,000 kilometers of the planet’s surface. Awardees range from universities to commercial companies, some of which have never worked with the U.S. Department of Defense. DARPA didn’t announce the total value of the agreements.
