Disruptive technologies are those that change the market and in most cases replace an existing technology. They are characterised by their capability to do so over a relatively short period of time. Some are known as 'killer applications' because they completely wipe out the opposition due to their placement in the market, their greater appeal, availability and lower price, to name just a few of the key factors. The replacement of Betamax video tape with VHS tape (even though the latter was technically inferior) was one classic example of a disruptive technology in the 1980s. Another example of disruptive technology was the way digital photography has replaced chemical photography. In just a few years, digital cameras have improved in quality, shutter speed, resolution, and most importantly pricing, to the point that the photographic giant Kodak this week announced the last batch processing of one of its iconic products - Kodachrome film.
As David Conrad recently wrote: The speed of the decline of the traditional wet film approach to photography has been spectacular. Yet in the early days of the digital camera it all seemed so unlikely. The cameras were low resolution, often in black-and-white only, and yet even so the machine just couldn't process the end result. There just weren't disks that could hold that amount of data. The idea that resolution, storage and processing power would increase to the point where a digital camera could rival the quality of a 35mm film image was, and to a certain extent still is, ridiculous.

The rapid rise of digital photography is due to the advantages of digital cameras over conventional cameras. Digital cameras are multi-functional, in some cases capable of recording video as well as capturing stills. The multiple affordance of digital media to be able to see instant results, record, delete, share and edit images on the move, and the ability to extract a great deal of information about camera source, geographical location and other useful information, are all attractions the conventional camera cannot compete with. Why wait several days or even hours to get colour prints when you can have them in seconds?
So what is disruptive activism? One of the clues lies in my presentations over the last couple of years on the ideas behind Edupunk. It's a subject I will revisit at the Learning without Frontiers conference in London next week. Along with Leigh Graves Wolf, I am hosting a hack conference session on the subject and will try to outline the philosophy behind the movement, and discuss how and why disruptive activism is necessary in education today. Edupunk is more than simply a 'do it yourself' philosophy. It's about challenging current practices, and in particular the commoditization of learning, and the manner in which edubusinesses are cashing in on gradually disappearing education budgets. Disruptive activism for me is about raising people's awareness to the alternatives that exist. It's about encouraging people to learn for themselves. It's about personalising learning. It's about finding new ways to do things that are more effective and more fit for purpose. It's not about being popular - people are free to shoot at me, and they often do. Disruptive activism is more about being dissatisfied with the status quo and not accepting that 'this is the way it should be'. Yes, we can be sure that one thing this new year will bring is change. I hope it will be the kind of change that disrupts bad practice and creates better opportunities for learning.
