Predicting the future is hard. Some small things, especially extending technology to say that this or that will become smaller, faster, cheaper and more efficient is the baseline. Predicting exactly what effect that will have on society is nearly impossible. You could "predict" that cameras will get smaller, networks faster and batteries more efficient, and you could put those together to predict tiny wireless spycams that run for months on a single battery charge. You might predict that such cameras would be worn on glasses to document people's lives, or used by perverts in public toilets and change rooms, but maybe you wouldn't think they would, for instance, be shotgunned into burning buildings for real-time mapping or used to monitor national parks or any number of other applications. What people think to do with technology is always unusual and always astounding.
