and floppy discs

Modern PDF signing creates a digital fingerprint showing the device it was used on, whose credentials were used, a timestamp, and even a location if location services are turned on.

But yea, I guess all that just can't compete with the ironclad security of a fucking ink pen. Oh, sorry. A copy of an ink pen. So much more secure and traceable.

There are some things where fax still makes sense

Nope.

Fax is insecure, you'd be better off signing w/o a "digital seal" or whatever and emailing it in. You can also print, sign, scan, and send, just like w/ a fax, but send as a PDF instead of insecurely over the telephone wires. I've done both digital signatures and scanned regular signatures, both work and are better than fax.
