Even though we live in a knowledge-based economy, walls are important nonetheless. Without the walls in the right places brains tend to wander aimlessly and have problems making connections. But walls also cost lot of money and have very long return on investment, therefore individuals or private companies have problems making the required investments. I prefer smaller government but I'm not a libertarian either. So I don't think governments can spur innovation by investing in start-ups, but I'm firm believer that governments have a very important role to play in setting the basic infrastructure in place where innovation can start to blossom. It was a joyful event, the opening ceremony of the new university buildings, that I was attending today. Of top importance for faculties of chemistry and computer science, of course, who found their new homes, but also for University of Ljubljana and broader Slovenia. No wonder than that the whole political and academic establishment of Slovenia showed themselves there to sunbath in gorgeous weather and media attention. Political speeches aside, it really was an important moment today. The walls which are now finally put in place just call for creativity to fill them in. And whoever come with an idea to put computer science faculty next to chemistry and biology should be congratulated for this stroke of genius (though, I'm pretty sure this was just a lucky coincidence of politics at play). The innovation possibilities of these three fields put together is breath-taking.
