In this post, Fabrizio Cardinali AI expert and founder of KNOWHEDGE, a venture building company holding stakes in half a dozen startups in Europe including AI companies Wavenure.ai, Braino.ai, SMarttrack.io and, last created, Myw.ai, takes a look at the revamped interest on Artificial Intelligence, and how new trends such as Machine Learning, Robotic Process Automation and Cognitive Technologies might bring together a great world to work and learn within in the next future, but perhaps with so smart machines around that the world might indeed become a great Disneyland for all of us…but perhaps a Disneyland without Children to be amused therein.
On May 5th 2016, TIME magazine summarized the views of the world’s smartest people about the revamped interest in Artificial Intelligence, AI, a controversial topic which for a long time has had the fervent support of science fiction fans but which has never made it far beyond pilots in the real world.
Amongst the supporters were Stephen Hawking, the famed 74-year-old theoretical physicist, Elon Musk, the outspoken 44-year-old entrepreneur and CEO of Tesla Motors, and Bill Gates, the 60-year-old computer software magnate and Microsoft co-founder, all of which praised the coming of computational intelligence to the cloud and at the same time cautioned us that it could potentially be “the last [event in our history], unless we learn how to avoid the risks.”
But it was Nick Bostrom, the 42-year-old director of Oxford’s Future of Humanity Institute, who took a dimmer view of the trend, warning that AI could quickly turn dark and dispose of humans, generating “economic miracles and technological awesomeness” within places of work, study and leisure, but with nobody there to benefit at the end,” like “a Disneyland without children.”
Whatever the outlook, if there is one prediction that we might have overlooked in promoting AI is that adding “machines” to the workplace we have to be sure to keep humans in the loop.
During public policy brainstorming events at the EU parliament and RD workprograms experts groups I was very keen to set time on the agenda to discuss the impact of AI on everyone from children to academics to adults to workforces…but the need for a new man-machine collaboration framework was never mentioned…it simply fell off our radar.
Today, we have evidence that a new wave of robotic automation is reaching the workplace. And this is taking place above all through the combined forces of smart data and (machine) learning, leaving us to seriously consider how we can keep humans in the loop of factory floors decision tacking and planning.
New computers now exist that are capable of completing working tasks whilst learning symbiotically from humans, achieving their goals at a fraction of the time and computing costs required from older robots. An early wave low cost robotic worker named Baxter, the latest build of the iRobot home cleaner from inventor Rodney Brook, and Yumi, the collaborative robot product released by ABB, are relevant samples of commoditized robotic workers you can “employ” for less than half of the cost of a junior FTE. Also, they can work 24/7, don’t need vacation time and, a point worth mentioning to some, don’t fall under any trade union protection laws (yet).
Even beyond these, today we have smart software solutions capable of both learning the repetitive actions of humans and executing them robotically. This trend, called Robotic Process Automation (RPA) or BOTs, demonstrates that in many applications, digital agents and assistants can not only do the work of humans, but do it faster, better and cheaper.
The vast majority of the 1,896 experts who responded to a study by the Pew Research Center believe that robots and digital agents, which cost approximately one-third of the price of an offshore full-time employee, will displace significant numbers of human workers in the near future, potentially affecting more than 100 million skilled workers by 2025.
Still, someone might argue that we still have a steady competitive lead as human workers over robots and that the singularity of having more robotic intelligence around us than human workers will never happen. At least not shot term.
Well, I couldn’t disagree more…
I first degreed in Bio-engineering and Artificial Intelligence in 1988 at the Engineering Faculty of Genoa, Italy, one of Europe’s first universities to offer an official qualification in such a new and emerging science. At the time, AI was all about computational logic, with costly Prolog programmers having to elicit reasoning intelligence capabilities using even more costly Lisp machines, all to emulate just a small fraction of the reasoning capability of a human being.
It took me a full thesis dissertation (more or less the equivalent of a year of work) to teach a shared Lisp machine (accessed on a very restricted weekly schedule) how to detect malignant tumours in digital images processed on a deicated Eidobrain MicroVAX system.
Still, that movement was enough to start a new wave in pursuit of “Holy Grail” expert systems, which we then predicted would be able to solve any human-based decision-making task, let alone detect suspicious images in digital tomography and X-ray images. Despite the initial high momentum, this intelligence never made it to massive adoption. The objectives were too ambitious. The computational power was too limited.
The costs were too high.
Today, big data feeds and machine learning technologies are democratically available, open source and on the cloud. The computation power of the cheapest smartphone on the market today exceeds that of my large MicroVAX station tens of thousands times over, not to mention comes dressed up with the sexy voice of Siri, Cortana or Alexa, your personal assistants of choice for the day.
But above all, today’s technologies can easily and cheaply reach and engage thousands of smart start-uppers and entrepreneurs who are looking for the next big thing to get behind following the dot-com and app vein burn-out.
So this time around, my gut feeling is that machine learning will happen at a faster pace than ever before, boosted by the power of the cloud and funded by the fuel of NASDAQ. It will be "the next big thing" in computer science, let alone in learning technologies, we are all looking for.
Faced with such an unprecedented level of acceleration, we must be sure to keep and cultivate human workforces who are still capable of learning better and faster than machines. We must keep our brains free to study further, ensuring that we continue to grow and hone our knowledge and mental capabilities to a level unattainable by even the most advanced machine. This is the only means by which we will be able to preserve the competitive edge that humans have in learning, and in (re)defining our learning objectives.
But be aware: IQ marks will not be the most important KPI in the human vs. machine learning competition; as Charles Darwin observed a long time ago, “It is not the strongest of the species that will survive, nor the most intelligent. It is the one that is most adaptable to change."
The reasoning capabilities of computers and robots are going to adapt very fast. So we must adapt faster. KPMG has classified the self-learning evolution of software into 3 classes (See Figure 1).
Fig 1. RPA (Robotic Process Automation) Tools Classification by KPMG – “Bots in the back office. The coming wave of digital workers” (KPMG, 2016)
Class 1 (Robotic Process Automation) exists today, and is starting to be embedded into platforms usually dealing with (human) workforce support and improvement.
There is increasing evidence that learning solutions originally meant to empower (human) workforces with the support of machines will gradually integrate machine learning capabilities to teach themselves how to robotize repetitive tasks and substitute human workforces and possibly reduced the time lost on tedious tasks in favour of better talent allocation.
Class 2, thaty of Cognitive technologies, offer a basic learning intelligence based on massive data. New solutions are experimenting with accessing big data series with cognitive technologies, such as Microsoft’s Cortana™ and IBM’s Watson™, which are capable of processing unstructured data and taking intelligent decisions on behalf of workers based on that knowledge. This represents a steady step into Class 2 (Cognitive Technologies) tools and architectures.
Finally, Class 3 (Cognitive Automation), the real advent of machine intelligence, will be based on accessing a diverse set of cognitive automation technologies and algos, accessible on a cloud-distributed and multi-service level, combining a variety of technologies such as language parsing, big data analytics and adaptive alteration. Such ML will be able to retrain itself and learn from experience. A first step towards the utopia of self training GAI (General AI).
The evolution of such classes will significantly advance the learning capabilities of machines, perhaps towards the singular breaking point of creating a machine capable of learning alone or even teaching other computers to do the same work at a shared workplace…something humans have never been really good at.
Today, we are still at the beginning of Class 2, and a stable, low-cost group of Class 3 technologies is most likely to be available only far beyond 5 years from now.
In essence, as robotics professor Masahiro Mori put it in 1970, we are still at the beginning of our walk towards the uncanny valley or “Bukimi no Tani Genshō (不気味の谷現象).” (see Figure 2)
Figure 2. Mori, M (2012) . “The uncanny valley “. IEEE Robotics & Automation Magazine.
Mori's original hypothesis stated that as the appearance of a robot is made more human, some observers' emotional response to the robot will become increasingly positive and empathic, until a point is reached beyond which the response quickly becomes that of strong revulsion, creating a downturn curve similar to that of a deep valley. However, as the robot's appearance continues to become less distinguishable from that of a human being, the emotional response becomes positive once again and approaches human-to-human empathy levels (See Figure 2).
So today, at the end of my +25 years engagement in promoting machine learning and AI at the workplace I am still positive on the results this will generate. I think we must indeed engage machines in our learning goals, and think ourselves at the beginning of such journey, distant from the fears and pitfalls of Mori’s uncanny valley. But the steadiness and pace of our journey relies deeply on our capability to maintain a competitive “learning edge” on the machines, balancing our capability to teach machines and possibly learn with them.
To ensure this, we must think of robots as working companions, making them more and more efficient in chosen tasks, meanwhile leveraging them to gain the freedom to put our time, talent and skills towards smarter, more qualifying and more valuable learning pursuits. In this way, we can retain our superior intelligence, and keep it comfortably out of reach of the singular “rise of the machines.”
At the same time, we must remain acutely aware that the capability of machines to learn will happen at a very fast and cheap pace, and smarter intelligence may not suffice to avoid a complete machine take-over, at least at the workplace…
So, for the time being, we can rest and enjoy the benefit of computational help in our workplaces. Our freed time can possibly be used trying to understand how humans can learn better using machines whilst we move forward.
But…we must also keep a cautious eye out on who will end up better adapting to the demands of today’s workplace to win the learning race and become the superior workforce of the future.
Will it be us or the machines?
