Re: Problem ?
If faxes work, and folks are used to them, what's the issue?
The issue is that much of the human race prefers illusion to things that actually work. There are some real problems with fax. It's slow, Isn't always provisioned with paper when it should be. Thermoprinted paper used in inexpensive fax machines fades over time. Etc, etc,etc. OTOH, the shiny digital solutions preferred by many tend to be costly, complex, not to be interoperable with other shiny digital solutions. etc,etc,etc. They have a bunch of problems of their own.
Personally, I belong to the "If it isn't broken, don't fix it" school. But some things really do work better after proper repair. The optimum way to deal with an older technology is probably to ask first if it really needs fixing, and second if there is a tested, widely deployed, solution that actually fixes real problems and doesn't come with unfortunate side effects.
