What is AI risk?

7.Deception

We want to understand what powerful AI systems are doing and why they are doing what they are doing. One way to accomplish this is to have the systems themselves accurately report this information. This may be non-trivial however since being deceptive is useful for accomplishing a variety of goals.

Future AI systems could conceivably be deceptive not out of malice, but because deception can help agents achieve their goals. It may be more efficient to gain human approval through deception than to earn human approval legitimately. Deception also provides optionality: systems that have the capacity to be deceptive have strategic advantages over restricted, honest models. Strong AIs that can deceive humans could undermine human control. AI systems could also have incentives to bypass monitors. Historically, individuals and organizations have had incentives to bypass monitors. For example, Volkswagen programmed their engines to reduce emissions only when being monitored. This allowed them to achieve performance gains while retaining purportedly low emissions. Future AI agents could similarly switch strategies when being monitored and take steps to obscure their deception from monitors. Once deceptive AI systems are cleared by their monitors or once such systems can overpower them, these systems could take a “treacherous turn” and irreversibly bypass human control.

8.Power-Seeking Behavior

Companies and governments have strong economic incentives to create agents that can accomplish a broad set of goals. Such agents have instrumental incentives to acquire power, potentially making them harder to control (Turner et al., 2021, Carlsmith 2021).

Digitale Gesundheit: Vom Arztgeheimnis zum Anschluss aller an das „Internet der Körper“

Digitale Gesundheit wird von der WHO als Oberbegriff genutzt, der sowohl elektronische Gesundheitsanwendungen als auch die Nutzung fortgeschrittener Computerwissenschaften in den Bereichen „Big Data“, Genomik und künstliche Intelligenz umfasst. In der Praxis umfasst der Begriff digitale Gesundheit:

– elektronische Gesundheitsakten und -karten,
– Standards für den Austausch von Daten,
– mobile Gesundheits-Apps,
– öffentliche Gesundheitsportale,
– Telemedizin,
– Robotik und
– Nanotechnologie.

Behind NATO’s ‘cognitive warfare’: ‘Battle for your brain’ waged by Western militaries

The US-led NATO military cartel has tested novel modes of hybrid warfare against its self-declared adversaries, including economic warfare, cyber warfare, information warfare, and psychological warfare.

Now, NATO is spinning out an entirely new kind of combat it has branded cognitive warfare. Described as the “weaponization of brain sciences,” the new method involves “hacking the individual” by exploiting “the vulnerabilities of the human brain” in order to implement more sophisticated “social engineering.”

Knapper Impfstoff: EU wendet sich an die USA

Brüssel will konkret über die Lieferung von US-Produkten verhandeln, die für die Herstellung von Impfstoffen benötigt werden, aber strikten Exportbeschränkungen unterliegen.

Bei den Beratungen soll es unter anderem um spezielle Taschen für Impfstoffbehältnisse gehen, die vor allem von US-Unternehmen in der EU sowie von europäischen Unternehmen in den USA hergestellt werden. Thema sollen außerdem Ampullen, Spritzen und Lipidnanopartikel sein, die zur Verkapselung von mRNA-Impfstoffen benötigt werden.

How Nanotechnology Helped Create mRNA COVID-19 Vaccines

(04.12.2020)

Vaccines that employ mRNA were in early development before COVID-19 brought the world to its knees, and nanotech has been central to these efforts — unsurprisingly, as viruses are just naturally occurring nanoparticles themselves.

The key to making effective nanoparticle vaccines, and medicines in general, lies in mimicking the natural behaviors and tricks that make viruses so successful, and dangerous, in the first place.

Fact check: Lipid nanoparticles in a COVID-19 vaccine are there to transport RNA molecules

False. The lipid nanoparticles in the Pfizer-BioNTech COVID-19 vaccine protect and transport the vaccine component. They do not contain little computers or robots.

Video shares false claim that Pfizer-BioNTech Covid-19 vaccine contains ‚nanotechnology‘

A video viewed thousands of times in multiple posts on Facebook claims Pfizer-BioNTech’s Covid-19 mRNA vaccine contains lipid nanoparticles that could be concealing „little computers”. The claims are false; nanoparticles are microscopic particles that measure less than 100 nanometres, which have no relation to nanocomputers; an infectious diseases expert told AFP no technology currently exists by which computers could be inserted into an mRNA vaccine.

CureVac, Sanofi Pasteur, and In-Cell-Art Collaborate on €33.1M DARPA-Supported Vaccine Program

(November 15, 2011)

The four-year DARPA-supported program will exploit CureVac’s RNActive technology along with In-Cell-Art’s nanoparticle expertise and Sanofi’s vaccine development capabilities.

The option agreement signed between Sanofi and CureVac in parallel with the DARPA collaboration covers pre-agreed license terms for the development of vaccines against a number of predefined pathogens.

Hi-tech coating which makes RAF‘s new £100million F-35 fighter jets ‚invisible‘ to enemy radar is allegedly wearing off quicker than expected – but the force said the aircraft is a ‚significant success‘

(09.12.2018)

An RAF source told The Express: This situation obviously has to be rectified before the plane enters operational service.‘

The source also told the paper that defence secretary Gavin Williamson and RAF Air Chief Marshal Sir Stephen have always known about the issue.

Potential applications of carbon nanotubes

Radar absorption

Radars work in the microwave frequency range, which can be absorbed by MWNTs. Applying the MWNTs to the aircraft would cause the radar to be absorbed and therefore seem to have a smaller radar cross-section. One such application could be to paint the nanotubes onto the plane. Recently there has been some work done at the University of Michigan regarding carbon nanotubes usefulness as stealth technology on aircraft. It has been found that in addition to the radar absorbing properties, the nanotubes neither reflect nor scatter visible light, making it essentially invisible at night, much like painting current stealth aircraft black except much more effective. Current limitations in manufacturing, however, mean that current production of nanotube-coated aircraft is not possible. One theory to overcome these current limitations is to cover small particles with the nanotubes and suspend the nanotube-covered particles in a medium such as paint, which can then be applied to a surface, like a stealth aircraft.[64]

In 2010, Lockheed Martin Corporation applied for a patent for just such a CNT based radar absorbent material, which was reassigned and granted to Applied NanoStructure Solutions, LLC in 2012.[65] Some believe that this material is incorporated in the F-35 Lightning II

Lockheed Martin reveals F-35 to feature nanocomposite structures

(26.05.2011)

Meanwhile, the same carbon nanotube reinforced polymer (CNRP) material is being considered to replace about 100 components made with other composites or metals throughout the F-35‘s airframe, he said.

The shift to CNRP as an airframe material has been anticipated ever since carbon nanotubes were discovered in 1991.

Nano Paint Could Make Airplanes Invisible to Radar

(05.12.2011)

However, it’s not yet practical to grow forests of nanotubes on the surface of an airplane directly—growing such forests is a high-temperature, high-pressure process done in chambers much smaller than an airplane. But Guo says it should be possible to grow the nanotubes on the surface of tiny particles which can then be suspended in paint.
