"A4 paper sheet-sized ceramic film could hold more than 2 TB of data" Just 2 TB? Makes you appreciate just how much 2 TB of data is.
Also, what's the point of "storing our future" if it is so difficult to read and decode? How would one even know where to look for the data if it's get lost. So besides doing it for fun I don't see the point of this and how it can be ever scaled to be in everyday use.
Right. This is probably just a start though. Just as Richard Feynman stated:
There's Plenty of Room at the Bottom.
I recently wanted to purchase a 3TB harddrive. The price is not that heavy (e,. g. at around 100 Euro), but I also realised that I'd much prefer that price to go down significantly. I am still in shock at the RAM prices. That is no longer affordable really.
