'The next big thing always starts out looking like nothing at all'

One of my favourite authors and speakers on all things innovation is Greg Satell.
He is a regular contributor to Inc. magazine and always has interesting insights into the future of innovations that will affect how we work.
In 'Why the future will always surprise us' he takes a look back at how past innovations emerged that at first appeared to be inconsequential.
Fleming's 'discovery' and failure to develop penicillin is well known, but this article gives several other examples of emergent technologies that turned out to be game changers.
Quantum computing looks like it may be one of those - nobody is certain how it will change everything, but we're absolutely certain it will.
