 "#ProjectSilica is a working demonstration of a system that can read and write data into small slabs of glass. Main draw of the technology is that it takes no energy to preserve data and the data can be retrieved rapidly if needed. The #glass offers extreme stability, with experiments suggesting the #data would be stable for over 10,000 years at room temperature."

@Heliograph Yes! That reminds me to talk to my tech helper about what I should do, if anything. (Brilliant kind former student)

@Heliograph wow! That would make storage interesting. Just hope it doesn't get corrupted in the span of its lifetime.

@skyfire747 also if this gets into the way of some rich dude wanting to get richer we won't hear about it again for another decade or three
