Superintelligence: Paths, Dangers, Strategies

Posted by in categories: biotech/medical, ethics, existential risks, robotics/AI

Since the release of ChatGPT in November 2022, artificial intelligence (AI) has both entered the common lexicon and sparked substantial public intertest. A blunt yet clear example of this transition is the drastic increase in worldwide Google searches for ‘AI’ from late 2022, which reached a record high in February 2024.

You would therefore be forgiven for thinking that AI is suddenly and only recently a ‘big thing.’ Yet, the current hype was preceded by a decades-long history of AI research, a field of academic study which is widely considered to have been founded at the 1956 Dartmouth Summer Research Project on Artificial Intelligence.1 Since its beginning, a meandering trajectory of technical successes and ‘AI winters’ subsequently unfolded, which eventually led to the large language models (LLMs) that have nudged AI into today’s public conscience.

Alongside those who aim to develop transformational AI as quickly as possible – the so-called ‘Effective Accelerationism’ movement, or ‘e/acc’ – exist a smaller and often ridiculed group of scientists and philosophers who call attention to the inherent profound dangers of advanced AI – the ‘decels’ and ‘doomers.’2 One of the most prominent concerned figures is Nick Bostrom, the Oxford philosopher whose wide-ranging works include studies of the ethics of human enhancement,3 anthropic reasoning,4 the simulation argument,5 and existential risk.6 I first read his 2014 book Superintelligence: Paths, Dangers, Strategies7 five years ago, which convinced me that the risks which would be posed to humanity by a highly capable AI system (a ‘superintelligence’) ought to be taken very seriously before such a system is brought into existence. These threats are of a different kind and scale to those posed by the AIs in existence today, including those developed for use in medicine and healthcare (such as the consequences of training set bias,8 uncertainties over clinical accountability, and problems regarding data privacy, transparency and explainability),9 and are of a truly existential nature. In light of the recent advancements in AI, I recently revisited the book to reconsider its arguments in the context of today’s digital technology landscape.

Single pixel imaging enabled by fiber laser arrays is expected to achieve remote detection

Posted by in category: computing

Single-pixel imaging (SPI) is a novel computational imaging technique that has been widely studied in recent years. This technique only uses a single pixel detector without spatial resolution to obtain the spatial information of the target.

Black hole singularities defy physics. New research could finally do away with them

Posted by in categories: cosmology, physics

Black hole singularities defy the laws of physics. New research presents a bold solution to this puzzle: Black holes may actually be a theoretical type of star called a ‘gravastar,’ filled with universe-expanding dark energy.

Breaking Light Speed: The Quantum Tunneling Enigma

Posted by in categories: particle physics, quantum physics

In an amazing phenomenon of quantum physics known as tunneling, particles appear to move faster than the speed of light. However, physicists from Darmstadt believe that the time it takes for particles to tunnel has been measured incorrectly until now. They propose a new method to stop the speed of quantum particles.

In classical physics, there are strict laws that cannot be circumvented. For instance, if a rolling ball lacks sufficient energy, it will not get over a hill; instead, it will roll back down before reaching the peak. In quantum physics, this principle is not quite so strict. Here, a particle may pass a barrier, even if it does not have enough energy to go over it. It acts as if it is slipping through a tunnel, which is why the phenomenon is also known as “quantum tunneling.” Far from mere theoretical magic, this phenomenon has practical applications, such as in the operation of flash memory drives.

Why a giant ‘cold spot’ in the cosmic microwave background has long perplexed astronomers

Posted by in category: cosmology

Leftover light from the young universe has a major flaw, and we don’t know how to fix it. It’s the cold spot. It’s just way too big and way too cold. Astronomers aren’t sure what it is, but they mostly agree that it’s worth investigating.

The cosmic microwave background (CMB) was generated when our universe was only 380,000 years old. At the time, our cosmos was about a million times smaller than it is today and had a temperature of over 10,000 kelvins (17,500 degrees Fahrenheit, or 9,700 degrees Celsius), meaning all of the gas was plasma. As the universe expanded, it cooled, and the plasma became neutral. In the process, it released a flood of white-hot light. Over the billions of years since, that light has cooled and stretched to a temperature of around 3 kelvins (minus 454 F, or minus 270 C), putting that radiation firmly in the microwave band of the electromagnetic spectrum.
