An AI System for Multiple-choice Tests

According to the New York Times, the Allen Institute for Artificial Intelligence unveiled a new system that correctly answered more than 90 percent of the questions on an eighth-grade science test and more than 80 percent on a 12th-grade exam. Is it really a breakthrough for AI technology, as the title of the article claims? This is a subject of controversy among experts. The newspaper is optimistic: “The system, called Aristo, is an indication that in just the past several months researchers have made significant progress in developing A.I. that can understand languages and mimic the logic and decision-making of humans.” (NYT, 4 September 2019) Aristo was built for multiple-choice tests. “It took standard exams written for students in New York, though the Allen Institute removed all questions that included pictures and diagrams.” (NYT, 4 September 2019) Some questions could be answered by simple information retrieval. There are numerous systems that access Google and Wikipedia, including artifacts of machine ethics like LIEBOT and BESTBOT. But for the answers to other questions logical thinking was required. Perhaps Aristo is helping to abolish multiple-choice tests – not so much because it can solve them, but because they are often not effective.

Punch the Robot

Robots are repeatedly damaged or destroyed. The hitchBOT is a well-known example.  But also the security robot K5 has become a victim of attacks several times. The latest case is described in the magazine Wired: “Every day for 10 months, Knightscope K5 patrolled the parking garage across the street from the city hall in Hayward, California. An autonomous security robot, it rolled around by itself, taking video and reading license plates. Locals had complained the garage was dangerous, but K5 seemed to be doing a good job restoring safety. Until the night of August 3, when a stranger came up to K5, knocked it down, and kicked it repeatedly, inflicting serious damage.” (Wired, 29 August 2019) The author investigates the question of whether one may attack robots. Of course you shouldn’t damage other people’s property. But what if the robot is a spy, a data collector, a profile creator? Digital self-defence (which exploits digital as well as analog possibilities) seems to be a proven tool not only in Hong Kong, but also in the US and Europe. The rights of robots that some demand cannot be a serious problem. Robots do not have rights. They feel nothing, they do not suffer, they have no consciousness. “So punch the robot, I tell you! Test the strength of your sociopolitical convictions on this lunk of inorganic matter!” (Wired, 29 August 2019)

Talk to the Shuttle

Olli 2.0 is born. Local Motors and IBM had presented an autonomous shuttle in 2016 that reminded of the Smart Shuttle operated by PostAuto AG in Sion, Valais. Unlike this one, however, Olli 1.0 could not only think but also speak, both at a high level and with the help of IBM Watson. Passengers’ wishes are accepted, for example with regard to destinations, and these are even suggested; when it is hot, the car drives to the nearest ice cream parlour. Olli could also reassure passengers or passers-by: “For citizens of Maryland, many of whom have never seen a self-driving car, Watson’s reassuring communications could be critical to making them more comfortable with the idea that there’s no human being at the wheel.” (Information IBM) Olli 2.0, launched in 2019, can not only access IBM Watson, but also Amazon’s deep learning chatbot service Lex. Something else is different from the predecessor: Olli is now 80% 3D-printed. This was reported by Techcrunch on August 31, 2019. The magazine contains more interesting information about the shuttle. By the way, it is intended for small areas, especially for trade fairs and university campuses. But like the Smart Shuttle, it has already been tested in small cities.

With Low-Tech against Digital Mass Surveillance

The resistance movement in Hong Kong uses different means of defence, communication and information. This is reported by the German news portal Heise on 1 September 2019. Demonstrators direct laser beams at the video cams, which are installed everywhere, not least in intelligent street lamps. The pointers are intended to interfere with the facial recognition systems used by the police to analyse some of the video streams. On television, one could see how the civil rights activists were able to use chain saws and ropes to bring down the high-tech street lights. Services such as Telegram and Firechat are used for communication and coordination. According to Quartz, “Hong Kong’s protesters are using AirDrop, a file-sharing feature that allows Apple devices to send photos and videos over Bluetooth and Wi-Fi, to breach China’s Great Firewall in order to spread information to mainland Chinese visitors in the city” (Quartz, 8 July 2019). You could read on a digital sticker distributed by AirDrop at subway stations: “Don’t wait until [freedom] is gone to regret its loss. Freedom isn’t god-given; it is fought for by the people.” (Quartz, 8 July 2019)

Simple Brain Waves in Organoids

Clusters of brain cells, so-called brain organoids, have been bred in the biologist’s lab at the University of California, San Diego. According to the New York Times, the scientists altered human skin cells into stem cells, then “coaxed them to develop as brain cells do in an embryo”. “The organoids grew into balls about the size of a pinhead, each containing hundreds of thousands of cells in a variety of types, each type producing the same chemicals and electrical signals as those cells do in our own brains.” (NYT, 29 August 2019) The progression was stimulated by various means. A few days ago, the scientists reported that they have recorded simple brain waves in these organoids. “In mature human brains, such waves are produced by widespread networks of neurons firing in synchrony. Particular wave patterns are linked to particular forms of brain activity, like retrieving memories and dreaming.” (NYT, 29 August 2019) Someday it may be possible to use brain organoids to develop inverted or reversed cyborgs. Another method could be to take an adult brain from a deceased creature. There is no doubt that many interesting philosophical questions arise in this context, such as the boundaries between humans and machines and the rights of such cyborgs.

Holograms in Teaching

Some universities strive to use holograms in their teaching. Through this technology, the lecturer’s representative would have a physical presence in space. Even interactions and conversations would be possible if the holograms or projections were connected to speech systems. Dr. David Lefevre, director of Imperial’s Edtech Lab, told the BBC one year ago: “The alternative is to use video-conferencing software but we believe these holograms have a much greater sense of presence”. American Samoa Community College (ASCC) has now switched on a digital platform that will stream 3D holograms of University of Hawaiʻi faculty members to deliver classes and engage with ASCC students in real-time. According to the website, students at the HoloCampus launch on August 20 received a lecture by UH Mānoa Water Resources Research Center researcher Chris Shuler on the subject of “sustainability and resilience” – a theme “with special significance for the people of American Samoa and Pacific Islands nations as they face challenges such as increasing plastic waste and more dramatic weather systems brought about by climate change” (Website University of Hawaiʻi). Holograms could play a role in all sorts of areas, including social and sexual relationships.

The Technological Fight against Mass Shootings

Security technologies are spreading more and more. Some of them, such as the security robot K5, guarantee and destroy security at the same time. Mass shootings such as those in Dayton and El Paso are a particular problem. New tech firms like Athena are offering solutions, as Fast Company reports. “Athena Security uses object-motion detection to spot when an individual brandishes a fireman, and immediately send an alert to their client, whether that’s a private security firm or local law enforcement. The company’s AI object-motion detection is camera agnostic, meaning it can work on any CCTV system. When a gun is detected, the video feed of the active shooter is made available to the client both on mobile devices and desktop computers, allowing officers to know what they are dealing with and where it is happening, all in the space of three seconds …” (Fast Company, 23 August 2019) In fact, technologies are often the only means against technologies. They may also be successful in preventing mass shootings. Another possibility would be to disarm the population – but this would meet with resistance in the USA. Another problem is that this is surveillance technology. Therefore, as with the K5 and other service robots, one thing applies: one form of security is gained, another form of security is lost.

The Reversed Cyborg

Chimeras in the biological and medical sense are organisms that consist of cells or tissues of different individuals and yet form closed and viable (not necessarily reproductive) organisms. They can be located within a species or between species and can be both plants and animals. There are natural (blood chimeras in mammals) and artificial mixed organisms (grafting in plants, animal-human embryos). Cyborgs are not chimeras in this sense. Nevertheless, research in this field might also be relevant for them, in particular for inverted or reversed cyborgs, for example robots in which an animal or human brain or organ is implanted. Animal-human chimeras for the production of human organs are regarded as unproblematic by many ethicists. According to a comment by Oliver Bendel, this is astonishing, since findings from animal ethics and veterinary medicine and in particular suffering and death of non-human living beings are ignored.

The System that Detects Fear

Amazon Rekognition is a well-known software for facial recognition, including emotion detection. It is used in the BESTBOT, a moral machine that hides an immoral machine. The immoral is precisely caused by facial recognition, which endangers the privacy of the user and his or her informational autonomy. The project is intended not least to draw attention to this risk. Amazon announced on 12 August 2019 that it has improved and expanded its system: “Today, we are launching accuracy and functionality improvements to our face analysis features. Face analysis generates metadata about detected faces in the form of gender, age range, emotions, attributes such as ‘Smile’, face pose, face image quality and face landmarks. With this release, we have further improved the accuracy of gender identification. In addition, we have improved accuracy for emotion detection (for all 7 emotions: ‘Happy’, ‘Sad’, ‘Angry’, ‘Surprised’, ‘Disgusted’, ‘Calm’ and ‘Confused’) and added a new emotion: ‘Fear’.” (Amazon, 12 August 2019) Because the BESTBOT accesses other systems such as MS Face API and Kairos, it can already recognize fear. So the change at Amazon means no change for this artifact of machine ethics.

Conversational Agents: Acting on the Wave of Research and Development

The papers of the CHI 2019 workshop “Conversational Agents: Acting on the Wave of Research and Development” (Glasgow, 5 May 2019) are now listed on convagents.org. The extended abstract by Oliver Bendel (School of Business FHNW) entitled “Chatbots as Moral and Immoral Machines” can be downloaded here. The workshop brought together experts from all over the world who are working on the basics of chatbots and voicebots and are implementing them in different ways. Companies such as Microsoft, Mozilla and Salesforce were also present. Approximately 40 extended abstracts were submitted. On 6 May, a bagpipe player opened the four-day conference following the 35 workshops. Dr. Aleks Krotoski, Pillowfort Productions, gave the first keynote. One of the paper sessions in the morning was dedicated to the topic “Values and Design”. All in all, both classical specific fields of applied ethics and the young discipline of machine ethics were represented at the conference. More information via chi2019.acm.org.
