That presenter needs to read the article I linked.
He claims fax has zero reliability due to "dog can eat the fax" (in a despirate grasp for straws) & "paper out".
I'm not convinced that running out of paper leads to a "success" ack & also lost data when paper is refilled. If it's true then it has merit but still nothing like the astronomical list of email reliability problems.
