But that's how it goes. As late as 2005, the real estate agents I worked with finally began to trust email over fax machines. It cracked an egg wide open for them. Now relying on email, they were able to do 10x the work (I have no real data BUT I do know their incomes went from low six figures to multiple six figures). Prior to their adoption, they just thought email was a novelty and legally couldn't be relied upon.
