Backing up your PGP key by hand

[Matt Borja]

So I guess all that leaves us with at this point is laser welded
inscriptions onto a block of metal, installed backwards as the cornerstone
of the next monument being preserved by a historic society.

It’ll be the next iteration of 3D printing: MIaaB (Metal Inscriptions as a
Backup).

Whole building would have to come down to restore from backup, but it’d at
least stand the test of weathering…
