Why would a renowned mathematician and computer scientist find himself drawn to the biosciences?

Interestingly, it appears that Turing’s fascination with this sub-discipline of biology most probably stemmed from the same source as the one that inspired his better known research: at that time all of these fields of knowledge were in a state of flux and development, and all posed challenging fundamental questions. Furthermore, in each of the three disciplines that engaged his interest, the matters to which he applied his uniquely creative vision were directly connected to central questions underlying these disciplines, and indeed to deeper and broader philosophical questions into the nature of humanity, intelligence and the role played by evolution in shaping who we are and how we shape our world.

Central to Turing’s biological work was his interest in mechanisms that shape the development of form and pattern in autonomous biological systems, and which underlie the patterns we see in nature (2), from animal coat markings to leaf arrangement patterns on plant stems (phyllotaxis). This topic of research, which he named “morphogenesis,” (3) had not been previously studied with modeling tools. This was a knowledge gap that beckoned Turing; particularly as such methods of research came naturally to him.

In addition to the diverse reasons that attracted him to the field of pattern formation, a major ulterior motive for his research had to do with a contentious subject which, astonishingly, is still highly controversial in some countries to this day. In studying pattern formation he was seeking to help invalidate the “argument from design(4) concept, which we know today as the hypothesis of “Intelligent Design.

Turing was intent on demonstrating that the laws of physics are sufficient to explain our observations in the natural world; or in other words, that our findings do not need an omnipotent creator to explain them. It is ironic that Turing, whose work played a central role in laying the groundwork for the creation of Artificial Intelligence (AI), took a clear stance against creationism. This is testament to his acceptance of scientific evidence and rigorous research over weak analogy.

Unfortunately, those who did not and will not accept Darwinian natural selection as the mechanism of evolution will not see anything compelling in Turing’s work on morphogenesis. To those individuals, the development of AI can be taken as “proof,” or a convincing analogy, of the necessity and presence of a creator, the argument being that the Creator created humanity, and humanity creates AI.

However, what the supporters of intelligent design do not acknowledge is that natural selection is itself precisely the cause underlying the development of both humanity and its AI progeny. Just as natural selection resulted in the phenomena that Turing sought to model in his work on morphogenesis (which brings about the propagation of successful traits through the development of biological form and pattern), it is also the driver for the development of intelligence. Itself generated via internalized neuronal selection mechanisms (5, 6), intelligence allows organisms to adapt to their environment continually during life.

Intelligence is the ultimate tool, the development of which allows organisms to survive; it enables them to learn, respond to their environment and adapt their behavior within their own lifetime. It is the fruit of the natural process that brings about successive development over time in organisms faced with scarcity of resources. Moreover, it now allows humans to defy generational selection and develop intelligences external to our own, making use of computational techniques, including some which utilize evolutionary mechanisms (7).

The eventual development of true AI will be a landmark in many ways, notably in that these intelligences will have the ability to alter their own circuits (their version of neurons), immediately and at will. While the human body is capable of some degree of non-developmental neuronal plasticity, this takes place slowly and control of the process is limited to indirect mechanisms (such as varied forms of learning or stimulation). In contrast, the high plasticity and directly controlled design and structure of AI software and hardware will render them well suited to altering themselves and hence to developing improved subsequent AI generations.

In addition to a jump in the degree of plasticity and its control, AIs will constitute a further step forward with regard to the speed at which beneficial information can be shared. In contrast to the exceedingly slow rate at which advantageous evolutionary adaptations were spread through the populations observed by Darwin (over several generations), the rapidly increasing rates of communication in current society result in successful “adaptations” (which we call science and technology) being distributed at ever-increasing speeds. This is, of course, the principal reason why information sharing is beneficial for humans – it allows us to better adapt to reality and harness the environment to our advantage. It seems reasonable to predict that ultimately the sharing of information in AI will be practically instantaneous.

It is difficult to speculate what a combination of such rapid communication and high plasticity combined with ever-increasing processing speeds will be like. The point at which self-improving AIs emerge has been termed a technological singularity (8).

Thus, in summary: evolution begets intelligence (via evolutionary neuronal selection mechanisms); human intelligence begets artificial intelligence (using, among others, evolutionary computation methods), which at increasing cycle speeds, leads to a technological singularity – a further big step up the evolutionary ladder.

Sadly, being considerably ahead of his time and living in an environment that castigated his lifestyle and drove him from his research, meant that Turing did not live to see the full extent of his work’s influence. While he did not survive to an age in which AIs became prevalent, he did fulfill his ambition by taking part in the defeat of argument from design in the scientific community, and witnessed Darwinian natural selection becoming widely accepted. The breadth of his vision, the insight he displayed, and his groundbreaking research clearly place Turing on an equal footing with the most celebrated scientists of the previous century.

Threats to humanity – the old and the resurgent https://lifeboat.com/blog/2008/09/threats-to-humanity-%e2%80%93-the-old-and-the-resurgent https://lifeboat.com/blog/2008/09/threats-to-humanity-%e2%80%93-the-old-and-the-resurgent#comments Tue, 02 Sep 2008 22:09:31 +0000 http://lifeboat.com/blog/?p=168

Following is a discussion of two potential threats to humanity – one which has existed for eons, the second we have seen recently resurfacing having thought it had been laid to rest.

First, a recent story on PhysOrg describes the work researchers at Vanderbilt University have performed in isolating antibodies from elderly people who had survived the 1918 flu pandemic. This comes three years after researchers at Mount Sinai and the Armed Forces Institute of Pathology in Washington, D.C isolated the same virus which caused this outbreak from the frozen bodies of people in Alaska who had died in the pandemic.

In addition to being an impressive achievement of biomedical science, which involved isolating antibody-secreting B cells from donors and generating “immortalized” cell lines to produce large amounts of antibodies, this research also demonstrates the amazing memory the immune system has (90 years!), as well as the ability scientists have to use tissue samples from people born nearly a century ago and fashion them into a potential weapon against future similar outbreaks. Indeed, these manufactured antibodies proved effective against 1918 flu virus when tested in mice.

Furthermore, such research provides tools which could help generate antibodies to treat other viruses which still blight humanity (such as HIV) or are seen as potential threats, such as avian influenza.

Second, nuclear annihilation. Russia’s recent foray into Georgia and the ensuing tensions with the west have brought the specter of the cold war back from the dead, and with it increasing levels of aggressive rhetoric from both sides and more or less veiled threats of action, some of it diplomatic, some military.

During the past twenty years, ever since the fall of the former Soviet Union, we have become used to living in a world no longer directly and overtly threatened by complete annihilation through world war III. Is this about to change? It would seem that despite current tensions, present conditions are far from fostering a renewed cold war.

Modern day Russia (and China can be described along similar lines) is inexorably tied to the world economy and does not represent a conflicting ideology striving for world domination as was the case during the most of the latter half of the twentieth century. This deep international integration stems from the almost global acceptance of the market economy as the preferred driving force for economic growth, albeit under different forms of government. Both Russia and China are (currently) fueled more by the will being recognized as premier global forces rather than the will to rule the world, the former wishing to return to its previous position and reclaim the respect it feels it lost during the last couple of decades, and the latter rising anew after centuries in the shadows.

Of course, the coming elections in the US may change the tone prevalent in the international brinkmanship game, although the involvement of the EU, led by French premier Sarkozy means that such strong statements coming from Western Europe are not set to change fundamentally.

So, unless further surprises are in store for us (a possibility which cannot be ignored when dealing with political and military maneuvering, especially those involving the tense conditions prevalent in many of the former Soviet republics), a compromise will eventually be reached and respected. The seeds of a calming effort have already been felt in recent days with much less inflammatory declarations from both sides, and signs of a Russian willingness to tone down at least the public face of disagreements with the EU and US. This is likely set to continue…at least until the next outbreak of nationalistic violence or political sword-brandishing in a region in which tensions run high.
