I'm not sure where this fax myth originates. I've been living in Germany for most of my life, and I'm no longer in my thirties. During this time, I have sent a total of zero faxes. I can't even remember anyone ever asking me to send one.
When doing my taxes, I've asked if I could send some required documents of my deceased father via email, and the lady _didn't even know if she had an external facing email address_. I was just to send it to info@, tell them to print it and put it on her desk. She also didn't have a direct phone line, so I had to call the central office first and ask them to connect me to her.
My mom runs a small business there and luckily she's got fax-to-email and email-to-fax. Just because younger people use other means of communication now doesn't mean it's a myth. It's very much there, and other means very much aren't.
One can so easily set-up a company without it so. 90% of what you read about companies and how to run and set them up im Germany on HN is wrong.
Fortunately, these times are over, and the company has celebrated the long overdue abolition of the fax machine ;-)
