This Sunday, it\u2018s Auke Hoekstras turn.\u00a0Here are all the previously published columns<\/a>.<\/i><\/p>\n

We are increasingly living in a world of exponential trends. Such trends are easy to devise and calculate, but difficult to believe. I realised that when, in 1990, I read a book by Ray Kurzweil (inspirer of Singularity University, among others) that predicted the rise of computers and the Internet. His method: analyse exponential growth. I thought it was so simple and logical that I immediately started calculating myself. Suddenly, the speed at which computers, the Internet, the Intranet and mobile phones was able to reach new heights became very predictable. But around me, disbelief reigned.<\/p>\n

Now I\u2019m working on predicting zero-emission applications in energy and mobility (as a researcher and director of my own company) and again: disbelief rules. Let me give you a clear example.<\/p>\n

In order to generate our current energy needs (not only electricity but everything) worldwide with solar panels, we need around 500 billion of them. At the moment, we only have a meager 1 million. That is 0.02%.<\/p>\n

Suppose we start with a factory that produces 1 solar panel per year. Suppose our factory produces 50% more each year. (This is approximately the average growth in solar panels over the past ten years). After two years we only produce two panels and after ten years we produce fifty panels a year. How many years will it then take us to produce the current 1 million solar panels? And how many years does it take to get from that 0.02% to 100%?<\/p>\n

The answer: it takes 32 years to reach 0.02% and it also takes 32 years to get from there to 100%! So if we continue in this way, all our energy\u00a0can come from solar panels in 2050! Unless you\u2019re working with exponential trends, you probably wouldn\u2019t have expected that to happen\u2026 It\u2019s almost incredible, isn\u2019t it?<\/p>\n

Now, this is not a prediction, because other energy sources are available as well and a multitude of nuances are possible, but it does indicate that things can go fast. On the other hand, the following figure shows the International Energy Agency\u2019s predictions about solar panels: they clearly do not yet believe in them.<\/p>\n

\"\"<\/a><\/p>\n

Sun is exponential because the main effort lies in thinking up the panels and the production processes. Once you\u2019ve come up with something smart, things can develop fast and others can build further on it.<\/p>\n

And often there are even multiple exponentials. Computers and graphics cards are developing exponentially (thanks to the gaming industry). Our knowledge of machine learning also develops exponentially but can also utilize exponentially growing hardware: a double exponential<\/em>. And autonomous driving works best with detailed maps, but they develop exponentially. It also needs machine learning and fast computers, but these are also developing exponentially. A fourfold exponential? In any case, things can go fast!<\/p>\n

If you\u00a0would simply have followed exponential trends blindly, you would often have predicted the future better than most experts in the past few years. At least in the field of solar panels, wind turbines, electric cars, batteries, hydrogen storage and autonomous driving. But of course, according to a researcher like me, that\u2019s not enough as an explanation. That\u2019s why I\u2019m working on \u201cagent-based\u201d models that can take into account a multitude of factors as well as persistent practice.<\/p>\n

Unfortunately, negative exponential developments can also go extremely fast. Is it still possible to slow down climate change? Will we soon be governed by Facebook or a malicious computer? Danger all around us!<\/p>\n

It is, therefore, important to learn to believe in (and calculate with) exponential trends. When we learn that, and then make smart choices, it is indeed true: tomorrow is good.<\/p>\n
