Within the period of 25 years, open source software has become pervasive. Used in data centres, cars, mobile devices and regular computers, this evolution has had an enormous impact on how we develop software as well as on the expectation level that is set to new software products. In this keynote, I will discuss this evolution from a researcher/developer perspective, and pinpoint some of the key things in the timeline. In addition, I will also present some ideas for future research as well as make predictions about the directions we are heading to.
