Advances in natural language processing have enabled systems such as Siri, Alexa, Google Assistant or Cortana to be at the service of anyone owning a smartphone or a computer. Still, so far, none of these systems managed to cross the thin dividing line that would make us take them for humans. When we ask Alexa to play music or Siri do dial a telephone number, we know very well that we are talking with a computer and the replies of the systems would remind us, were we to forget that.

It was to be expected that, with the evolution of the technology, this type of interactions would become more and more natural, possibly reaching a point where a computer could impersonate a real human, taking us closer to the vision of Alan Turing, a situation where you cannot tell a human apart from a computer by simply talking to both.

In an event widely reported in the media, at the I/O 2018 conference, Google made a demonstration of Duplex, a system that is able to process and execute requests in specific areas, interacting in a very human way with human operators. While Google states that the system is still under development, and only able to handle very specific situations, you get a feeling that, soon enough, digital assistants will be able to interact with humans without disclosing their artificial nature.  You can read the Google AI blog post here, or just listen to a couple of examples, where Duplex is scheduling a haircut or making a restaurant reservation. Both the speech recognition system and the speech synthesis system, as well as the underlying knowledge base and natural language processing engines, operate flawlessly in these cases, anticipating a widely held premonition that AI systems will soon be replacing humans in many specific tasks.

European Commission releases communication on Artificial Intelligence

Today, April 25th, 2018, the European Commission released a communication entitled Artificial Intelligence for Europe, and a related press release, addressing what could become the European strategy for Artificial Intelligence.

The document states that “Like the steam engine or electricity in the past, AI is transforming our world, our society and our industry. Growth in computing power, availability of data and progress in algorithms have turned AI into one of the most strategic technologies of the 21st century.

The communication argues that “The EU as a whole (public and private sectors combined) should aim to increase this investment [in Artificial Intelligence] to at least EUR 20 billion by the end of 2020. It should then aim for more than EUR 20 billion per year over the following decade.” These values should be compared with the current value of 4-5 billion, spent in AI.

The communication also addresses some questions raised by the increased ability of AI systems to replace human jobs: “The first challenge is to prepare the society as a whole. This means helping all Europeans to develop basic digital skills, as well as skills which are complementary to and cannot be replaced by any machine such as critical thinking, creativity or management. Secondly, the EU needs to focus efforts to help workers in jobs which are likely to be the most transformed or to disappear due to automation, robotics and AI. This is also about ensuring access for all citizens, including workers and the self-employed, to social protection, in line with the European Pillar of Social Rights. Finally, the EU needs to train more specialists in AI, building on its long tradition of academic excellence, create the right environment for them to work in the EU and attract more talent from abroad.”

This initiative, which has already received significant press coverage, may become Europe’s answer to the strong investments China and the United States are making in Artificial Intelligence technologies. There is also a fact sheet about the communication.

The Second Machine Age

The Second Machine Age, by Erik Brynjolfsson and Andrew McAfee, two MIT professors and researchers, offers mostly an economist’s point of view on the consequences of the technological changes that are remaking civilisation.

Although a fair number of chapters is dedicated to the technological innovations that are shaping the first decades of the 21st century, the book is at its best when the economic issues are presented and discussed.

The book is particularly interesting in its treatment of the bounty vs. spread dilema: will economic growth be fast enough to lift everyone’s standard of living, or will increased concentration of wealth lead to such an increase in inequality that many will be left behind?

The chapter that provides evidence on the steady increase in inequality is specially appealing and convincing. While average income, in the US, has been increasing steadily in the last decades, median income (the income of those who are exactly in the middle of the pay scale) has stagnated for several decades, and may even be decreasing in the last few years. For the ones at the bottom at the scale, the situation is much worst now than decades ago.

Abundant evidence of this trend also comes from the analysis of the shares of GDP that are due to wages and to corporate profits. Although these two fractions of GDP have fluctuated somewhat in the last century, there is mounting evidence that the fraction due to corporate profits is now increasing, while the fraction due to wages is decreasing.

All this evidence, put together, leads to the inevitable conclusion that society has to explicitly address the challenges posed by the fourth industrial revolution.

The last chapters are, indeed, dedicated to this issue. The authors do not advocate a universal basic income, but come out in defence of a negative income tax for those whose earnings are below a given level. The mathematics of the proposal are somewhat unclear but, in the end, one thing remains certain: society will have to address the problem of mounting inequality brought in by technology and globalisation.

The wealth of humans: work and its absence in the twenty-first century

The Wealth of Humans, by Ryan Avent, a senior editor at The Economist, addresses the economic and social challenges imposed on societies by the rapid development of digital technologies.  Although the book includes an analysis of the mechanisms, technologies, and effects that may lead to massive unemployment, brought by the emergence of digital technologies, intelligent systems, and smart robots, the focus is on the economic and social effects of those technologies.

The main point Avent makes is that market mechanisms may be relied upon to create growth and wealth for society, and to improve the average condition of humans, but cannot be relied upon to ensure adequate redistribution of the generated wealth. Left to themselves, the markets will tend to concentrate wealth. This happened in the industrial revolution, but society adapted (unions, welfare, education) to ensure that adequate redistribution mechanisms were put in place.

To Avent, this tendency towards increased income asymmetry, between the top earners and the rest, which is already so clear, will only be made worst by the inevitable glut of labor that will be created by digital technologies and artificial intelligence.

There are many possible redistribution mechanisms, from universal basic income to minimum wage requirements but, as the author points out, none is guaranteed to work well in a society where a large majority of people may become unable to find work. The largest and most important asymmetry that remains is, probably, the asymmetry that exists between developed countries and underdeveloped ones. Although this asymmetry was somewhat reduced by the recent economic development of the BRIC countries, Avent believes that was a one time event that will not reoccur.

Avent points out that the strength of the developed economies is not a direct consequence of the factors that are most commonly thought to be decisive: more capital, adequate infrastructures, and better education. These factors do indeed play a role but what makes the decisive difference is “social capital”, the set of rules shared by members of developed societies that makes them more effective at creating value for themselves and for society. Social capital, the unwritten set of rules that make it possible to create value, in a society, in a country or in a company, cannot be easily copied, sold, or exported.

This social capital (which, interestingly, closely matches the idea of shared beliefs Yuval Harari describes in Sapiens) can be assimilated, by immigrants or new hires, who can learn how to contribute to the creation of wealth, and benefit from it. However, as countries and societies became adverse at receiving immigrants, and companies reduce workforces, social capital becomes more and more concentrated.

In the end, Avent concludes that no public policies, no known economic theories, are guaranteed to fix the problem of inequality, mass unemployment, and lack of redistribution. It comes down to society, as whole, i.e., to each one of us, to decide to be generous and altruistic, in order to make sure that the wealth created by the hidden hand of the market benefits all of mankind.

A must-read if you care about the effects of asymmetries in income distribution on societies.

Europe wants to have one exascale supercomputer by 2023

On March 23rd, in Rome, seven European countries signed a joint declaration on High Performance Computing (HPC), committing to an initiative that aims at securing the required budget and developing the technologies necessary to acquire and deploy two exascale supercomputers, in Europe, by 2023. Other Member States will be encouraged to join this initiative.

Exascale computers, defined as machines that execute 10 to the 18th power operations per second will be roughly 10 times more powerful than the existing fastest supercomputer, the Sunway TaihuLight, which clocks in at 93 petaflop/s, or 93 times 10 to the 15 floating point operations per second. No country in Europe has, at the moment, any machine among the 10 most powerful in the world. The declaration, and related documents, do not fully specify that these machines will clock at more than one exaflop/s, given that the requirements for supercomputers are changing with the technology, and floating point operations per second may not be the right measure.

This renewed interest of European countries in High Performance Computing highlights the fact that this technology plays a significant role in the economic competitiveness of research and development. Machines with these characteristics are used mainly in complex system simulations, in physics, chemistry, materials, fluid dynamics, but they are also useful in storing and processing the large amounts of data required to create intelligent systems, namely by using deep learning.

Andrus Ansip, European Commission Vice-President for the Digital Single Market remarked that: “High-performance computing is moving towards its next frontier – more than 100 times faster than the fastest machines currently available in Europe. But not all EU countries have the capacity to build and maintain such infrastructure, or to develop such technologies on their own. If we stay dependent on others for this critical resource, then we risk getting technologically ‘locked’, delayed or deprived of strategic know-how. Europe needs integrated world-class capability in supercomputing to be ahead in the global race. Today’s declaration is a great step forward. I encourage even more EU countries to engage in this ambitious endeavour”.

The European Commission press release includes additional information on the next steps that will be taken in the process.

Sapiens: A Brief History of Humankind

Historian Yuval Noah Harari‘s best seller book, Sapiens is a hard-to-put-down analysis of the reasons Homo sapiens became not only the dominant species of planet Earth, but also the only one that can control its destiny.

It is difficult to summarize a book that covers the whole of human history, and also a bit of the future. However, Harari’s main point is that the most unique characteristic of our species is not the intelligence of individual human beings, nor some unique quality (a soul, maybe) that only humans possess, much less the ability to stand erect and to create tools. Instead, it is our unique ability to believe and act on collective fictions, created and passed on, over time and space, by language, culture and behavior.

One hundred thousand years ago, humans were already as smart as they are today, were able to make tools, and lived in small groups that could be a threat to the survival of large animals. However, they did not have the ability to change the planet, an ability that only appeared recently, in evolutionary terms.

According to Harari, what makes the human species so different from other species is the ability of humans to create collective fictions that are used to coordinate the actions of thousands, hundreds of thousands, or even millions of human beings. These fictions, the result of what could be called “collective hallucinations”, have created first the agricultural revolution and then the technological revolutions that led to today’s world. It is the ability to create these collective fictions that made Homo sapiens unique, in its ability to transform and also to destroy the world.

Almost anything that is important in today’s society fits into this wide category of a collective fictions or, as he also calls them, religions. Money is, of course, a collective fiction, not valuable by itself, but only because everyone believes in it. But the concept also encompasses religions, political systems, philosophical beliefs, and even several concepts in ethics. Harari’s convincing arguments put at the same level (and calls them nothing else than collective fictions, or religions) systems as diverse as Christianism, Islamism, Capitalism, Marxism, Socialism, Nazism, Humanism, Liberalism, and Democracy. Harari argues that even ideas so commonly accepted as nations, corporations, afterlife, human rights or the sanctity of human life are nothing more than a shared belief, held by almost everyone today, but relatively recent in historical terms.

The argument is powerful, and the book very engaging, a real page turner. As a side benefit, Sapiens is also a grandiose lesson in history, from the prehistoric times to the rise and fall of modern empires, full of surprising facts and wonderful tales.

Intel buys Mobileye by $15 billion

Mobileye, a company that develops computer vision and sensor fusion technology for autonomous and computer assisted driving, has been bought by Intel, in a deal worth 15.3 billion dollars.

The company develops a large range of technologies and services related with computer based driving. These technologies include rear facing and front facing cameras, sensor fusions, and high-definition mapping. Mobileye has been working with a number of car manufacturers, including Audi and BMW.

Mobileye already sells devices that you install in your car, to monitor the road and warn the driver of impeding risks. A number of insurance companies in Israel have reduced the insurance premium for drivers who have installed the devices in their cars.

This sale is another strong indication that autonomous and computer assisted driving will be a mature technology within the next decade, changing profoundly our relation with cars and driving.

The products of Mobileye have been extensively covered in the news recently, including TechCrunchThe New York Times and Forbes.
