New technique reveals centuries of secrets in locked letters

I would have expected: ...mailed, not in envelopes, but rather...

Maybe it’s the fact that I am not seeing the surrounding context with your quote, but it reads fine to me.

Perhaps it is my own way of thinking & writing which enables this. I was told by my mother that she knows when she’s reading something I wrote versus my siblings.

Otherwise, perhaps it is related to when one reads misspelled or incomplete words, yet our brains enable us to understand what was meant anyway, and in some cases, this is only consciously realized upon a second read.

It looks fine to me. A lot of the press targets a 6-8th grade reading level. This sentence structure probably violates those rules, I guess.

Thanks to institutions such as the Internet Archive, I do not believe that is true.

There will always be a lunatic who encoded his entire usb stick in a granite block somewhere to be found in a 1000 years from now.

On the scale of millennia, I wouldn't be too worried; disasters happen to any storage medium, and even our knowledge of Greek and Roman society today comes from surprisingly few sources. I think the bigger concern is the near-term effect of something like an EMP event, the digital library of papyruses burning down.

Letters from 1000 years ago obviously have great historical value, but it's not like they're the only kind of record that exists. We still print books, newspapers, government edicts, contracts, invoices, and photographs. We still hang plaques.

In a 1000 years there will be PhDs specializing in just the analysis of Twitter during 2016.
