Hans Peter Moravec (born November 30, 1948, Kautzen, Austria) is computer scientist and an adjunct faculty member at the Robotics Institute of Carnegie Mellon University in Pittsburgh, USA. He is known for his work on robotics, artificial intelligence, and writings on the impact of technology. Moravec also is a futurist with many of his publications and predictions focusing on transhumanism. Moravec developed techniques in computer vision for determining the region of interest (ROI) in a scene.

Career

Moravec attended Loyola College in Montreal for two years and transferred to Acadia University, where he received his BSc in mathematics in 1969. He received his MSc in computer science in 1971 from the University of Western Ontario. He then earned a PhD in computer science from Stanford University in 1980 for a TV-equipped robot which was remote controlled by a large computer (the Stanford Cart [2] ). The robot was able to negotiate cluttered obstacle courses. Another achievement in robotics was the discovery of new approaches for robot spatial representation such as 3D occupancy grids. He also developed the idea of bush robots.

Moravec joined the newly established Robotics Institute at Carnegie Mellon in 1980 as a research scientist, becoming research professor in 1995. He has been an adjunct professor at the institute since 2005. [1]

Moravec was a cofounder of Seegrid Corporation [3] of Pittsburgh, Pennsylvania, [4] in 2003 which is a robotics company with one of its goals being to develop a fully autonomous robot capable of navigating its environment without human intervention.

He is also somewhat known for his work on space tethers. [5]

Futurism

Predictions

Hans Moravec has made some concrete predictions as to the future of intelligence, by estimating the computational cost (measured in instructions per second) of various operations of human intelligence, and comparing it with the future of computer computational power as predicted by Moore's law.

In When will computer hardware match the human brain (1998), [6] he estimated that human brains operate at about instructions per second, and that, if Moore's law continues, a computer with the same speed would cost only 1000 USD (1997 dollars) in mid-2020s, thus "computers suitable for humanlike robots will appear in the 2020s".

Mind Children

In his 1988 book Mind Children, [7] Moravec outlines Moore's law and predictions about the future of artificial life. Moravec outlines a timeline and a scenario in this regard, [8] [9] in that the robots will evolve into a new series of artificial species, starting around 2030–2040. [10]

Moravec also outlined the "neural substitution argument" in Mind Children [7] :109-122, published 7 years before David Chalmers published a similar argument in his paper "Absent Qualia, Fading Qualia, Dancing Qualia", which is sometimes cited as the source of the idea. The neural substitution argument is that if each neuron in a conscious brain can be replaced successively by an electronic substitute with the same behavior as the neuron it replaces, then a biological consciousness would be transferred seamlessly into an electronic computer, thus proving that consciousness does not depend on biology and can be treated as an abstract computable process.

Robot: Mere Machine to Transcendent Mind

In Robot: Mere Machine to Transcendent Mind, published in 1999, Moravec further considers the implications of evolving robot intelligence, generalizing Moore's law to technologies predating the integrated circuit, and extrapolating it to predict a coming "mind fire" of rapidly expanding superintelligence.

Arthur C. Clarke wrote about this book: "Robot is the most awesome work of controlled imagination I have ever encountered: Hans Moravec stretched my mind until it hit the stops." [11] David Brin also praised the book: "Moravec blends hard scientific practicality with a prophet's far-seeing vision." [12] On the other hand, the book was reviewed less favorably by Colin McGinn for The New York Times. McGinn wrote, "Moravec … writes bizarre, confused, incomprehensible things about consciousness as an abstraction, like number, and as a mere "interpretation" of brain activity. He also loses his grip on the distinction between virtual and real reality as his speculations spiral majestically into incoherence." [13]

The Chinese room argument holds that a computer executing a program cannot have a mind, understanding, or consciousness, regardless of how intelligently or human-like the program may make the computer behave. The argument was presented in a 1980 paper by the philosopher John Searle entitled "Minds, Brains, and Programs" and published in the journal Behavioral and Brain Sciences. Before Searle, similar arguments had been presented by figures including Gottfried Wilhelm Leibniz (1714), Anatoly Dneprov (1961), Lawrence Davis (1974) and Ned Block (1978). Searle's version has been widely discussed in the years since. The centerpiece of Searle's argument is a thought experiment known as the Chinese room.

The technological singularity—or simply the singularity—is a hypothetical future point in time at which technological growth becomes uncontrollable and irreversible, resulting in unforeseeable consequences for human civilization. According to the most popular version of the singularity hypothesis, I. J. Good's intelligence explosion model of 1965, an upgradable intelligent agent could eventually enter a positive feedback loop of self-improvement cycles, each successive; and more intelligent generation appearing more and more rapidly, causing a rapid increase ("explosion") in intelligence which would ultimately result in a powerful superintelligence, qualitatively far surpassing all human intelligence.

Mind uploading is a speculative process of whole brain emulation in which a brain scan is used to completely emulate the mental state of the individual in a digital computer. The computer would then run a simulation of the brain's information processing, such that it would respond in essentially the same way as the original brain and experience having a sentient conscious mind.

Sentience is the ability to experience feelings and sensations. It may not necessarily imply higher cognitive functions such as awareness, reasoning, or complex thought processes. Sentience is an important concept in ethics, as the ability to experience happiness or suffering often forms a basis for determining which entities deserve moral consideration, particularly in utilitarianism.

Artificial consciousness, also known as machine consciousness, synthetic consciousness, or digital consciousness, is the consciousness hypothesized to be possible in artificial intelligence. It is also the corresponding field of study, which draws insights from philosophy of mind, philosophy of artificial intelligence, cognitive science and neuroscience.

The experiences of the atomic scientists clearly show the need to take personal responsibility, the danger that things will move too fast, and the way in which a process can take on a life of its own. We can, as they did, create insurmountable problems in almost no time flat. We must do more thinking up front if we are not to be similarly surprised and shocked by the consequences of our inventions.

In futures studies and the history of technology, accelerating change is the observed exponential nature of the rate of technological change in recent history, which may suggest faster and more profound change in the future and may or may not be accompanied by equally profound social and cultural change.

<span class="mw-page-title-main">History of artificial intelligence</span>

The history of artificial intelligence (AI) began in [ancient history|antiquity], with myths, stories and rumors of artificial beings endowed with intelligence or consciousness by master craftsmen. The study of logic and formal reasoning from antiquity to the present led directly to the invention of the programmable digital computer in the 1940s, a machine based on the abstract essence of mathematical reasoning. This device and the ideas behind it inspired a handful of scientists to begin seriously discussing the possibility of building an electronic brain.

The philosophy of artificial intelligence is a branch of the philosophy of mind and the philosophy of computer science that explores artificial intelligence and its implications for knowledge and understanding of intelligence, ethics, consciousness, epistemology, and free will. Furthermore, the technology is concerned with the creation of artificial animals or artificial people so the discipline is of considerable interest to philosophers. These factors contributed to the emergence of the philosophy of artificial intelligence.

A bush robot is a hypothetical machine whose body branches in a fractal way into trillions of nanoscale fingers, to achieve very high dexterity and reconfigurability. The concept was described by Hans Moravec in a final report for NASA in 1999, who projected that development of the necessary technology will take half a century.

In the history of artificial intelligence, an AI winter is a period of reduced funding and interest in artificial intelligence research. The field has experienced several hype cycles, followed by disappointment and criticism, followed by funding cuts, followed by renewed interest years or even decades later.

The following outline is provided as an overview of and topical guide to artificial intelligence:

Moravec's paradox is the observation in the fields of artificial intelligence and robotics that, contrary to traditional assumptions, reasoning requires very little computation, but sensorimotor and perception skills require enormous computational resources. The principle was articulated in the 1980s by Hans Moravec, Rodney Brooks, Marvin Minsky, and others. Moravec wrote in 1988: "it is comparatively easy to make computers exhibit adult level performance on intelligence tests or playing checkers, and difficult or impossible to give them the skills of a one-year-old when it comes to perception and mobility".
