why aren't fax machines next to the buggy whip

I ordered cable modem service for my office and had to sign a 10 page contract basically stating that I would keep it for 2 years or more. I don't believe I promised sexual favors to the salesman. No idea on why it took 10 pages of legal gibberish, but I suppose lawyers have to eat. Anyhow, the sales idiot wanted to fax me the contract so I could sign it and fax it back to him. Time out idiot! I don't have a fax machine because I went paperless when the century rolled into the 21st. I then reminded the modern Neatherthal that his supposedly high tech company should also be paperless. They do promote the sale of their cable modem for highspeed internet access. Why not email me the contract and I'll email a signed version back. Is that so high tech?

Why do fax machines still exist? Do their users not understand the digital age with electronic communications. Paper should be saved for the John Crapper throne room.
