It may have started with the ability to replicate signatures, but even during the internet age, fax does have one interesting advantage.
It uses a dedicated circuit to communicate rather than using packets.
By that I mean that two fax machines that are connected to send a fax are electronically linked together in a dedicated circuit for the duration of the session, and all the data takes the same path.
This is in stark contrast to an email, which is split up into packets which may take quite different paths to reach the other destination.
