Digitising everything you see, for 80 years, 16 hours a day, at 512Kbps requires 97TB of data capacity. At the rate at which data densities are growing, that will be possible in 14 years.

Soon you could have a device which would give you the perfect memory for your lifetime. At any point in your life, you can look back and see exactly what you were doing at any given time. Also, it stays in your backpack while you access its content by bashing away on a (spare public) wireless keyboard and peering into a similarly equipped monitor.


Or a public display screen. Such a system might be able to detect and utilise any local hardware. At the airport, it would transmit your personal itinerary, cross-referenced with flight and gate information from a local server, onto the monitor you happen to be standing under.

Thanks to The Reg for that one.
