Why Now Is A Great Time To Consider A Career In Open Source Hardware

Twenty years or so ago, almost no one even knew what open source hardware was, let alone planned a career around it. In 2000, for example, out of the more than 2 million academic papers published that year in the entire world, only seven articles even mentioned "open source hardware" at all. When I first wrote Open-Source Lab, I'd collected every example (only a few dozen) and could easily keep up and read every open hardware article that got published to post them on a wiki. I am happy to report that is no longer physically possible. There have already been over 1,500 articles that discuss "open source hardware" this year, and I am sure many more will be out by year's end. Open source hardware is now a field of its own, with a few journals dedicated to it specifically (for example, HardwareX and the Journal of Open Hardware). In a wide range of fields, dozens of traditional journals now routinely cover the latest open hardware developments.
