Most of my career, I've watched with great interest as tech memes come and go.
Like viruses, their eventual success can be measured by their reach. Some stay isolated to small, focused populations. Others break out and dramatically change the way we think about things.
Unlike viruses, certain tech memes do much good if they are spread widely. Consider "the web" or "big data" if you will. These powerful ideas transcended the tech world, and eventually redefined how business leaders and policy makers charted their paths forward.
When it comes to "software defined" anything, I often feel that we as technologists haven't successfully made our case to those outside the technology world. There are very powerful ideas at play here, with the clear potential to change how we think about things going forward.
But to bring about that positive change, we're going to have to get much better at infecting others :)
