Blogging can be broken down into several sub-sets of bloggers. One sub-set of bloggers is the blogger that blogs their life. They just publish what they are doing - all the time. One short-cut in the future could be just to literally record your entire life.

In the future, some could carry around what I would call a “LifeBlog” or “LifeLog” recorder. It would be a tiny recorder that records video and sound with a large amount of digital storage.

With future advances in storage– a device that some could carry and record their entire life – will be completely possible.

The implications, of course, will cause several related discussions about personal privacy. But, other, positive things could come in the areas of medicine (what happened during a heart attack, etc.), education (record lessons), crime prevention (what happened during a robbery, etc…), and don’t forget spousal arguments about who said what.

A device the size of a sugar cube will be able to record and store high resolution video footage of every second of a human life within two decades, experts said yesterday.

Researchers said governments and societies must urgently debate the implications of the huge increases in computing power and the growing mass of information being collected on individuals.

Some fear that the advent of "human black boxes" combined with the extension of medical, financial and other digital records will lead to loss of privacy and a dramatic expansion of the nanny state.

Others highlight positive advances in medicine, education, crime prevention and the way history will be recorded.
