Cerf says that if we do not find a solution, our 21st century will be an information "black hole" for future generations.
Wanganui District Council is aware of the issue and has specialist staff already addressing how we store and archive important information.
The problem is that anything on computers - photos, documents, presentations, software, video games - is all just data. People look at photos and don't realise that, without the software to decode it, those images don't exist. As technology advances, various methods of accessing data may be lost.
In the age of the internet, Facebook and other social media, it is hard to imagine that future generations may not be able to access data about us, and " like the Middle Ages " they may not know much about us.
For businesses and councils, where some information needs to stored and be able to be accessed forever, it is a worrying thought that in 50 years' time, we cannot access anything we are storing today. But is it a real problem or just digital doom and gloom?
