Aleksandra Przegalińska: Artificial intelligence is shattering the framework in which we’ve operated so far.
Patryk Zakrzewski: It’s often said that the decades-long history of research into artificial intelligence is divided into winters and summers: periods of increased interest in this topic and stagnation. Right now, we’re back in one of those intense periods, with reports of new developments coming in all the time. What are the groundbreaking developments that have happened in this field over the past year?
Aleksandra Przegalińska: This idea of winters and summers is a bit problematic because voices keep emerging thatwhich contest this sharp divide that suggests there have only been, so far, periods of decline and flourishment in the work on artificial intelligence. It has rather been a much more complicated and fluid story. Of course, the term ‘AI winter’ is still in circulation and still frightens people. On the other hand, there are opinions, for instance from the well-known robotics scientist Ben Goertzel, that there has never been such a period. There have been periods when there was less funding and less general interest in AI, but that doesn’t mean innovative projects didn’t emerge during those times. Some very good expert systems were created during one ‘winter’, and some groundbreaking robotics solutions during another. Others postulate that we should add ‘spring’ to the equation. MIT researchers, for example, argue that we’re currently experiencing the season before the full blossoming of AI capabilities.
In any case, this warm season in the development of artificial intelligence has lasted for a long time, and it’s not like the year 2020 was an important boundary line in this field. The most important, groundbreaking things happened in the 2000s – especially in 2009 and 2010. That’s when deep neural networks were developed. But we’re still discovering their capabilities: processing images, photos, and numerical data. Year after year, the number of new applications increases. This is the breakthrough we’re working on all the time: the emergence of brain-inspired neural networks and the emergence of methods such as learning by reinforcement, used in the most recent networks which learn by gaining experience in a manner similar to humans.
The past year has certainly been interesting because of the development of the medtech sector, which is the application of artificial intelligence to study vaccines, find pharmacological therapies, and track the development of pandemics. Then there are all the telemedical solutions, such as chatbots used in healthcare. I think an important part of this was that artificial intelligence entered a sphere that isn’t controversial. The capabilities of artificial
intelligence here are much more useful to people than when it’s used in the banking sector or marketing. This has led many people to understand that artificial intelligence can actually be helpful. This is evident from the fact that medtech start-ups have been enjoying success for some time now, whereas previously they tried knocking on investors’ doors to no avail.
If I had to name some breakthroughs from the past year, they would be two more projects that seem extremely interesting, although we don’t quite know the implications yet. One, of course, is GPT-3, a text generator that’s based on deep neural network solutions. It does excellent text processing and wrote a very interesting article for The Guardian. It has many interesting potential applications, and in 2021 we will surely learn about more of them. The second piece of recent news is about the creation of MuZero, a neural network created by DeepMind, which can play games of all kinds (including chess, Go, and Shogi) and can also transfer skills gained in one game to another.
